0dc327459b gdb: Remove vec.{c,h} and update code to not include vec.h
Removes vec.c and vec.h from the source tree, and remove all the
remaining includes of vec.h.  There should be no user visible changes
after this commit.

I did have a few issues rebuilding GDB after applying this patch due
to cached dependencies, I found that running this command in the build
directory resolved my build issues without requiring a 'make clean':

    rm -fr gdb/gdbserver/gdbsupport/.deps/

e43b10e10e Remove the ui_out_style_kind enum
This removes the ui_out_style_kind enum, in favor of simply using
ui_file_style references.  This simplifies the code somewhat.

fd3619828e bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions.  The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections.  Those sections shouldn't be modified
anyway.

The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma.  I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section.  This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

590042fc45 Make first and last lines of 'command help documentation' consistent.
With this patch, the help docs now respect 2 invariants:
  * The first line of a command help is terminated by a '.' character.
  * The last character of a command help is not a newline character.

Note that the changes for the last invariant were done by Tom, as part of :
 [PATCH] Remove trailing newlines from help text
 https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html
but some occurrences have been re-introduced since then.

Some help docs had to be rephrased/restructured to respect the above
invariants.

Before this patch, print_doc_line was printing the first line
of a command help documentation, but stopping at the first '.'
or ',' character.

This was giving inconsistent results :
  * The first line of command helps was sometimes '.' terminated,
    sometimes not.
  * The first line of command helps was not always designed to be
    readable/understandable/unambiguous when stopping at the first
    '.' or ',' character.

This e.g. created the following inconsistencies/problems:
< catch exception -- Catch Ada exceptions
< catch handlers -- Catch Ada exceptions
< catch syscall -- Catch system calls by their names
< down-silently -- Same as the `down' command
while the new help is:
> catch exception -- Catch Ada exceptions, when raised.
> catch handlers -- Catch Ada exceptions, when handled.
> catch syscall -- Catch system calls by their names, groups and/or numbers.
> down-silently -- Same as the `down' command, but does not print anything.

Also, the command help doc should not be terminated by a newline
character, but this was not respected by all commands.
The cli-option -OPT framework re-introduced some occurences.
So, the -OPT build help framework was changed to not output newlines at the
end of %OPTIONS% replacement.

This patch changes the help documentations to ensure the 2 invariants
given above.

It implied to slightly rephrase or restructure some help docs.

Based on the above invariants, print_doc_line (called by
'apropos' and 'help' commands to print the first line of a command
help) now outputs the full first line of a command help.

This all results in a lot of small changes in the produced help docs.
There are less code changes than changes in the help docs, as a lot
of docs are produced by some code (e.g. the remote packet usage settings).

046bebe1c0 Add more styling to "disassemble"
This adds more styling to the disassemble command.  In particular,
addresses and function names in the disassembly are now styled.

This required fixing a small latent bug in set_output_style.  This
function always passed NULL to emit_style_escape; but when writing to
a file other than gdb_stdout, it should emit the style escape
directly.  (FWIW this is another argument for better integrating the
pager with ui_file and getting rid of this entire layer.)

0d12e84cfc Don't include gdbarch.h from defs.h
I touched symtab.h and was surprised to see how many files were
rebuilt.  I looked into it a bit, and found that defs.h includes
gdbarch.h, which in turn includes many things.

gdbarch.h is only needed by a minority ofthe files in gdb, so this
patch removes the include from defs.h and updates the fallout.

I did "wc -l" on the files in build/gdb/.deps; this patch reduces the
line count from 139935 to 137030; so there are definitely future
build-time savings here.

Note that while I configured with --enable-targets=all, it's possible
that some *-nat.c file needs an update.  I could not test all of
these.  The buildbot caught a few problems along these lines.

268a13a5a3 Rename common to gdbsupport
This is the next patch in the ongoing series to move gdbsever to the
top level.

This patch just renames the "common" directory.  The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top.  This approach makes the patches a bit
more tractable.

I chose the name "gdbsupport" for the directory.  However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.

Tested by the buildbot.

eedc3f4f0a Replace throw_exception with throw in some cases
This replaces throw_exception with "throw;" when possible.  This was
written by script.  The rule that is followed is that uses of the
form:

   catch (... &name)
     {
       ...
       throw_exception (name);
     }

... can be rewritten.  This should always be safe, because exceptions
are caught by const reference, and therefore can't be modified in the
body of the catch.

230d2906b9 Rename gdb exception types
This renames the gdb exception types.  The old types were only needed
due to the macros in common-exception.h that are now gone.

The intermediate layer of gdb_exception_RETURN_MASK_ALL did not seem
needed, so this patch removes it entirely.

3d6e9d2336 Make exceptions use std::string and be self-managing
This changes the exception's "message" member to be a shared_ptr
wrapping a std::string.  This allows removing the stack of exception
messages, because now exceptions will self-destruct when needed.  This
also adds a noexcept copy constructor and operator= to gdb_exception,
plus a "what" method.

a068643d69 Change pid_to_str to return std::string
Currently the target pid_to_str method returns a const char *, so many
implementations have a static buffer that they update.  This patch
changes these methods to return a std::string instead.  I think this
is cleaner and avoids possible gotchas when calling pid_to_str on
different ptids in a single statement.  (Though no such calls exist
currently.)

This also updates various helper functions, and the gdbarch pid_to_str
methods.

I also made a best effort to fix all the callers, but I can't build
some of the *-nat.c files.

Tested by the buildbot.

This commit applies all changes made after running the gdb/copyright.py
script.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

cbe5657196 Add output styles to gdb
This adds some output styling to the CLI.

A style is currently a foreground color, a background color, and an
intensity (dim or bold).  (This list could be expanded depending on
terminal capabilities.)

A style can be applied while printing.  For ui-out, this is done by
passing the style constant as an argument.  For low-level cases,
fprintf_styled and fputs_styled are provided.

Users can control the style via a number of new set/show commands.  In
the interest of not typing many nearly-identical documentation
strings, I automated this.  On the down side, this is not very
i18n-friendly.

I've chose some default colors to use.  I think it would be good to
enable this by default, so that when users start the new gdb, they
will see the new feature.

Stylizing is done if TERM is set and is not "dumb".  This could be
improved when the TUI is available by using the curses has_colors
call.  That is, the lowest layer could call this without committing to
using curses everywhere; see my other patch for TUI colorizing.

I considered adding a new "set_style" method to ui_file.  However,
because the implementation had to interact with the pager code, I
didn't take this approach.  But, one idea might be to put the isatty
check there and then have it defer to the lower layers.

3dcfdc5865 Fix compile error with clang 3.8
When compiling with clang 3.8 (default clang version on Debian
Stretch, the current stable), we get errors like this:

  CXX    dtrace-probe.o
../../binutils-gdb/gdb/dtrace-probe.c:103:31: error: default initialization of an object of const type 'const dtrace_static_probe_ops' without a user-provided default constructor
const dtrace_static_probe_ops dtrace_static_probe_ops;
                              ^

Silence them by value-initializing those objects.  It's not necessary
with other compilers (later clang versions, gcc), but it shouldn't
hurt either.

66b4deae03 target_ops::to_stratum -> target_ops::stratum() virtual method
Given that a target's stratum is a property of the type, and not of an
instance of the type, get rid of to_stratum data field and replace it
with a virtual method.

I.e., when we have e.g., 10 target remote instances active, there's no
need for each of the instances to have their own to_stratum copy.

0803633106 Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc.
As preparation for multi-target, this patch makes each inferior have
its own thread list.

This isn't absolutely necessary for multi-target, but simplifies
things.  It originally stemmed from the desire to eliminate the
init_thread_list calls sprinkled around, plus it makes it more
efficient to iterate over threads of a given inferior (no need to
always iterate over threads of all inferiors).

We still need to iterate over threads of all inferiors in a number of
places, which means we'd need adjust the ALL_THREADS /
ALL_NON_EXITED_THREADS macros.  However, naively tweaking those macros
to have an extra for loop, like:

     #define ALL_THREADS (thr, inf) \
       for (inf = inferior_list; inf; inf = inf->next) \
	 for (thr = inf->thread_list; thr; thr = thr->next)

causes problems with code that does "break" or "continue" within the
ALL_THREADS loop body.  Plus, we need to declare the extra "inf" local
variable in order to pass it as temporary variable to ALL_THREADS
(etc.)

It gets even trickier when we consider extending the macros to filter
out threads matching a ptid_t and a target.  The macros become tricker
to read/write.  Been there.

An alternative (which was my next attempt), is to replace the
ALL_THREADS etc. iteration style with for_each_all_threads,
for_each_non_exited_threads, etc. functions which would take a
callback as parameter, which would usually be passed a lambda.
However, I did not find that satisfactory at all, because the
resulting code ends up a little less natural / more noisy to read,
write and debug/step-through (due to use of lambdas), and in many
places where we use "continue;" to skip to the next thread now need to
use "return;".  (I ran into hard to debug bugs caused by a
continue/return confusion.)

I.e., before:

    ALL_NON_EXITED_THREADS (tp)
      {
	if (tp->not_what_I_want)
	  continue;
	// do something
      }

would turn into:

    for_each_non_exited_thread ([&] (thread_info *tp)
      {
	if (tp->not_what_I_want)
	  return;
	// do something
      });

Lastly, the solution I settled with was to replace the ALL_THREADS /
ALL_NON_EXITED_THREADS / ALL_INFERIORS macros with (C++20-like) ranges
and iterators, such that you can instead naturaly iterate over
threads/inferiors using range-for, like e.g,.:

   // all threads, including THREAD_EXITED threads.
   for (thread_info *tp : all_threads ())
     { .... }

   // all non-exited threads.
   for (thread_info *tp : all_non_exited_threads ())
     { .... }

   // all non-exited threads of INF inferior.
   for (thread_info *tp : inf->non_exited_threads ())
     { .... }

The all_non_exited_threads() function takes an optional filter ptid_t as
parameter, which is quite convenient when we need to iterate over
threads matching that filter.  See e.g., how the
set_executing/set_stop_requested/finish_thread_state etc. functions in
thread.c end up being simplified.

Most of the patch thus is about adding the infrustructure for allowing
the above.  Later on when we get to actual multi-target, these
functions/ranges/iterators will gain a "target_ops *" parameter so
that e.g., we can iterate over all threads of a given target that
match a given filter ptid_t.

The only entry points users needs to be aware of are the
all_threads/all_non_exited_threads etc. functions seen above.  Thus,
those functions are declared in gdbthread.h/inferior.h.  The actual
iterators/ranges are mainly "internals" and thus are put out of view
in the new thread-iter.h/thread-iter.c/inferior-iter.h files.  That
keeps the gdbthread.h/inferior.h headers quite a bit more readable.

A common/safe-iterator.h header is added which adds a template that
can be used to build "safe" iterators, which are forward iterators
that can be used to replace the ALL_THREADS_SAFE macro and other
instances of the same idiom in future.

There's a little bit of shuffling of code between
gdbthread.h/thread.c/inferior.h in the patch.  That is necessary in
order to avoid circular dependencies between the
gdbthread.h/inferior.h headers.

As for the init_thread_list calls sprinkled around, they're all
eliminated by this patch, and a new, central call is added to
inferior_appeared.  Note how also related to that, there's a call to
init_wait_for_inferior in remote.c that is eliminated.
init_wait_for_inferior is currently responsible for discarding skipped
inline frames, which had to be moved elsewhere.  Given that nowadays
we always have a thread even for single-threaded processes, the
natural place is to delete a frame's inline frame info when we delete
the thread.  I.e., from clear_thread_inferior_resources.

79b8d3b090 Fix use-after-free in record_btrace_start_replaying
-fsanitize=address showed a use-after-free in
record_btrace_start_replaying.  The bug occurred because
get_thread_current_frame returned a frame_info, but this object was
then invalidated before the return by ~scoped_restore_current_thread.

This patch fixes the problem by renaming get_thread_current_frame and
having it return a frame id.

b926417afa Simple -Wshadow=local fixes
This fixes all the straightforward -Wshadow=local warnings in gdb.  A
few standard approaches are used here:

* Renaming an inner (or outer, but more commonly inner) variable;
* Lowering a declaration to avoid a clash;
* Moving a declaration into a more inner scope to avoid a clash,
  including the special case of moving a declaration into a loop header.

I did not consider any of the changes in this patch to be particularly
noteworthy, though of course they should all still be examined.

f2ffa92bbc gdb: Eliminate the 'stop_pc' global
In my multi-target work, I need to add a few more
scoped_restore_current_thread and switch_to_thread calls in some
places, and in some lower-level places I was fighting against the fact
that switch_to_thread reads/refreshes the stop_pc global.

Instead of piling on workarounds, let's just finally eliminate the
stop_pc global.  We already have the per-thread
thread_info->suspend.stop_pc field, so it's mainly a matter of using
that more/instead.

00431a78b2 Use thread_info and inferior pointers more throughout
This is more preparation bits for multi-target support.

In a multi-target scenario, we need to address the case of different
processes/threads running on different targets that happen to have the
same PID/PTID.  E.g., we can have both process 123 in target 1, and
process 123 in target 2, while they're in reality different processes
running on different machines.  Or maybe we've loaded multiple
instances of the same core file.  Etc.

To address this, in my WIP multi-target branch, threads and processes
are uniquely identified by the (process_stratum target_ops *, ptid_t)
and (process_stratum target_ops *, pid) tuples respectively.  I.e.,
each process_stratum instance has its own thread/process number space.

As you can imagine, that requires passing around target_ops * pointers
in a number of functions where we're currently passing only a ptid_t
or an int.  E.g., when we look up a thread_info object by ptid_t in
find_thread_ptid, the ptid_t alone isn't sufficient.

In many cases though, we already have the thread_info or inferior
pointer handy, but we "lose" it somewhere along the call stack, only
to look it up again by ptid_t/pid.  Since thread_info or inferior
objects know their parent target, if we pass around thread_info or
inferior pointers when possible, we avoid having to add extra
target_ops parameters to many functions, and also, we eliminate a
number of by ptid_t/int lookups.

So that's what this patch does.  In a bit more detail:

- Changes a number of functions and methods to take a thread_info or
  inferior pointer instead of a ptid_t or int parameter.

- Changes a number of structure fields from ptid_t/int to inferior or
  thread_info pointers.

- Uses the inferior_thread() function whenever possible instead of
  inferior_ptid.

- Uses thread_info pointers directly when possible instead of the
  is_running/is_stopped etc. routines that require a lookup.

- A number of functions are eliminated along the way, such as:

  int valid_gdb_inferior_id (int num);
  int pid_to_gdb_inferior_id (int pid);
  int gdb_inferior_id_to_pid (int num);
  int in_inferior_list (int pid);

- A few structures and places hold a thread_info pointer across
  inferior execution, so now they take a strong reference to the
  (refcounted) thread_info object to avoid the thread_info pointer
  getting stale.  This is done in enable_thread_stack_temporaries and
  in the infcall.c code.

- Related, there's a spot in infcall.c where using a RAII object to
  handle the refcount would be handy, so a gdb::ref_ptr specialization
  for thread_info is added (thread_info_ref, in gdbthread.h), along
  with a gdb_ref_ptr policy that works for all refcounted_object types
  (in common/refcounted-object.h).

b6a8c27bb8 target_ops::beneath -> target_ops::beneath()
This changes target_ops::beneath from a pointer to a method, and
adjusts all references throughout.  The idea here is to make it easier
to change the target stack representation from an intrusive singly
linked list to something else without leaking implementation details
throughout.

The commit does not change the representation yet, that will be done
in a following patch.  That is why a new target_ops::m_beneath field
appears here.  That new field isn't really documented properly or made
private, simply because it will be removed shortly.

Note that target_ops::beneath() is essentially the same as the current
find_target_beneath routine.  The following patch will eliminate the
latter.

d9f719f1ad target factories, target open and multiple instances of targets
Currently, to open a target, with "target TARGET_NAME", GDB finds the
target_ops instance with "TARGET_NAME" as short name, and then calls
its target_ops::open virtual method.  In reality, there's no actual
target/name lookup, a pointer to the target_ops object was associated
with the "target TARGET_NAME" command at add_target time (when GDB is
initialized), as the command's context.

This creates a chicken and egg situation.  Consider the case of
wanting to open multiple remote connections.  We want to be able to
have one remote target_ops instance per connection, but, if we're not
connected yet, so we don't yet have an instance to call target->open()
on...

This patch fixes this by separating out common info about a target_ops
to a separate structure (shortname, longname, doc), and changing the
add_target routine to take a reference to such an object instead of a
pointer to a target_ops, and a pointer to a factory function that is
responsible to open an instance of the corresponding target when the
user types "target TARGET_NAME".

 -extern void add_target (struct target_ops *);
 +extern void add_target (const target_info &info, target_open_ftype *func);

I.e. this factory function replaces the target_ops::open virtual
method.

For static/singleton targets, nothing changes, the target_open_ftype
function pushes the global target_ops instance on the target stack.
At target_close time, the connection is tor down, but the global
target_ops object remains live.

However, targets that support being open multiple times will make
their target_open_ftype routine allocate a new target_ops instance on
the heap [e.g., new remote_target()], and push that on the stack.  At
target_close time, the new object is destroyed (by the
target_ops::close virtual method).

Both the core target and the remote targets will support being open
multiple times (others could/should too, but those were my stopping
point), but not in this patch yet.  We need to get rid of more globals
first before that'd be useful.

Native targets are somewhat special, given find_default_run_target &
friends.  Those routines also expect to return a target_ops pointer,
even before we've open the target.  However, we'll never need more
than one instance of the native target, so we can assume/require that
native targets are global/simpletons, and have the backends register a
pointer to the native target_ops.  Since all native targets inherit
inf_child_target, we can centralize that registration.  See
add_inf_child_target, get_native_target/set_native_target and
find_default_run_target.

f6ac5f3d63 Convert struct target_ops to C++
I.e., use C++ virtual methods and inheritance instead of tables of
function pointers.

Unfortunately, there's no way to do a smooth transition.  ALL native
targets in the tree must be converted at the same time.  I've tested
all I could with cross compilers and with help from GCC compile farm,
but naturally I haven't been able to test many of the ports.  Still, I
made a best effort to port everything over, and while I expect some
build problems due to typos and such, which should be trivial to fix,
I don't expect any design problems.

* Implementation notes:

- The flattened current_target is gone.  References to current_target
  or current_target.beneath are replaced with references to
  target_stack (the top of the stack) directly.

- To keep "set debug target" working, this adds a new debug_stratum
  layer that sits on top of the stack, prints the debug, and delegates
  to the target beneath.

  In addition, this makes the shortname and longname properties of
  target_ops be virtual methods instead of data fields, and makes the
  debug target defer those to the target beneath.  This is so that
  debug code sprinkled around that does "if (debugtarget) ..."  can
  transparently print the name of the target beneath.

  A patch later in the series actually splits out the
  shortname/longname methods to a separate structure, but I preferred
  to keep that chance separate as it is associated with changing a bit
  the design of how targets are registered and open.

- Since you can't check whether a C++ virtual method is overridden,
  the old method of checking whether a target_ops implements a method
  by comparing the function pointer must be replaced with something
  else.

  Some cases are fixed by adding a parallel "can_do_foo" target_ops
  methods.  E.g.,:

    +  for (t = target_stack; t != NULL; t = t->beneath)
	 {
    -      if (t->to_create_inferior != NULL)
    +      if (t->can_create_inferior ())
	    break;
	 }

  Others are fixed by changing void return type to bool or int return
  type, and have the default implementation return false or -1, to
  indicate lack of support.

- make-target-delegates was adjusted to generate C++ classes and
  methods.

  It needed tweaks to grok "virtual" in front of the target method
  name, and for the fact that methods are no longer function pointers.
  (In particular, the current code parsing the return type was simple
  because it could simply parse up until the '(' in '(*to_foo)'.

  It now generates a couple C++ classes that inherit target_ops:
  dummy_target and debug_target.

  Since we need to generate the class declarations as well, i.e., we
  need to emit methods twice, we now generate the code in two passes.

- The core_target global is renamed to avoid conflict with the
  "core_target" class.

- ctf/tfile targets

  init_tracefile_ops is replaced by a base class that is inherited by
  both ctf and tfile.

- bsd-uthread

  The bsd_uthread_ops_hack hack is gone.  It's not needed because
  nothing was extending a target created by bsd_uthread_target.

- remote/extended-remote targets

  This is a first pass, just enough to C++ify target_ops.

  A later pass will convert more free functions to methods, and make
  remote_state be truly per remote instance, allowing multiple
  simultaneous instances of remote targets.

- inf-child/"native" is converted to an actual base class
  (inf_child_target), that is inherited by all native targets.

- GNU/Linux

  The old weird double-target linux_ops mechanism in linux-nat.c, is
  gone, replaced by adding a few virtual methods to linux-nat.h's
  target_ops, called low_XXX, that the concrete linux-nat
  implementations override.  Sort of like gdbserver's
  linux_target_ops, but simpler, for requiring only one
  target_ops-like hierarchy, which spares implementing the same method
  twice when we need to forward the method to a low implementation.
  The low target simply reimplements the target_ops method directly in
  that case.

  There are a few remaining linux-nat.c hooks that would be better
  converted to low_ methods like above too.  E.g.:

   linux_nat_set_new_thread (t, x86_linux_new_thread);
   linux_nat_set_new_fork (t, x86_linux_new_fork);
   linux_nat_set_forget_process

  That'll be done in a follow up patch.

- We can no longer use functions like x86_use_watchpoints to install
  custom methods on an arbitrary base target.

  The patch replaces instances of such a pattern with template mixins.
  For example memory_breakpoint_target defined in target.h, or
  x86_nat_target in x86-nat.h.

- linux_trad_target, MIPS and Alpha GNU/Linux

  The code in the new linux-nat-trad.h/c files which was split off of
  inf-ptrace.h/c recently, is converted to a C++ base class, and used
  by the MIPS and Alpha GNU/Linux ports.

- BSD targets

  The

    $architecture x NetBSD/OpenBSD/FreeBSD

  support matrix complicates things a bit.  There's common BSD target
  code, and there's common architecture-specific code shared between
  the different BSDs.  Currently, all that is stiched together to form
  a final target, via the i386bsd_target, x86bsd_target,
  fbsd_nat_add_target functions etc.

  This introduces new fbsd_nat_target, obsd_nat_target and
  nbsd_nat_target classes that serve as base/prototype target for the
  corresponding BSD variant.

  And introduces generic i386/AMD64 BSD targets, to be used as
  template mixin to build a final target.  Similarly, a generic SPARC
  target is added, used by both BSD and Linux ports.

- bsd_kvm_add_target, BSD libkvm target

  I considered making bsd_kvm_supply_pcb a virtual method, and then
  have each port inherit bsd_kvm_target and override that method, but
  that was resulting in lots of unjustified churn, so I left the
  function pointer mechanism alone.

4a4495d62d btrace: set/show record btrace cpu
Add new set/show commands to set the processor that is used for enabling
errata workarounds when decoding branch trace.

The general format is "<vendor>:<identifier>" but we also allow two
special values "auto" and "none".

The default is "auto", which is the current behaviour of having GDB
determine the processor on which the trace was recorded.

If that cpu is not known to the trace decoder, e.g. when using an old
decoder on a new system, decode may fail with "unknown cpu".  In most
cases it should suffice to 'downgrade' decode to assume an older cpu.
Unfortunately, we can't do this automatically.

The other special value, "none", disables errata workarounds.

76727919ce Convert observers to C++
This converts observers from using a special source-generating script
to be plain C++.  This version of the patch takes advantage of C++11
by using std::function and variadic templates; incorporates Pedro's
patches; and renames the header file to "observable.h" (this change
eliminates the need for a clean rebuild).

Note that Pedro's patches used a template lambda in tui-hooks.c, but
this failed to compile on some buildbot instances (presumably due to
differing C++ versions); I replaced this with an ordinary template
function.

Regression tested on the buildbot.

7ea78b5973 btrace: Remove ui_out cleanups
This patch replaces the cleanups that close the list and tuple of the
btrace instruction history output with ui_out_emit_tuple and
ui_out_emit_list.

This patch replaces two VEC(tp_t) with std::vector<thread_info *>, which
allows to remove two cleanups.  To make it easier to map the old code to

ordered_remove/unordered_remove.

798a7429f9 Remove some unused variables
This patch removes some unused variables, found with -Wunused.  I have
not removed everything reported by -Wunused, because some expressions
such as

  struct type *arg_type = check_typedef (value_type);

in bfin-tdep.c could have an unexpected but important side-effect.  I
removed others that I considered more low-risk, such as:

  struct gdbarch *gdbarch = get_objfile_arch (objfile);

ac7936dfd0 s/get_regcache_arch (regcache)/regcache->arch ()/g
This patches removes get_regcache_arch, and use regache->arch () instead.
The motivation of this change is that I am going to move some basic stuff
into a base class of regcache.  I don't need to update "client" code
regcache->arch ().  On the other hand, this patch shortens the code a
little bit.

981a3fb359 Constify add_prefix_cmd
This changes add_prefix_cmd to accept a const-taking function as an
argument; then fixes up all the callers.

In a couple of spots I had to add a non-const overload of a function,
because the function is passed to two different command-adding
"constructors".  These overloads are temporary; once constification is
complete they can be removed.

This patch also fixes a typo I happened to notice while constifying.

Note that this touches a couple of files (gnu-nat.c and go32-nat.c)
that I can't build.  So, while I made a best-effort there, I am not
certain they will still compile.

Tested by rebuilding.
