dda83cd783 gdb, gdbserver, gdbsupport: fix leading space vs tabs issues 
Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c).  I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it?  What if the lines around it are also
wrong, do I fix them too?  I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.

So I propose to fix as much as possible once and for all (hopefully).

One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines.  My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for.  So you
already need a somewhat efficient way to do this.

Using some interactive tool, rather than plain git-blame, makes this
trivial.  For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too.  My point is that it won't
really make archeology more difficult.

The other typical counter argument is that it will cause conflicts with
existing patches.  That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve.  I have also tried "git
rebase --ignore-whitespace", it seems to work well.  Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).

51a948fdf0 gdb: Have allocate_target_description return a unique_ptr 
Update allocate_target_description to return a target_desc_up, a
specialisation of unique_ptr.

This commit does not attempt to make use of the unique_ptr in the
best possible way, in almost all cases we immediately release the
pointer from within the unique_ptr and then continue as before.

There are a few places where it was easy to handle the unique_ptr, and
in these cases I've done that.

Everything under gdb/features/* is auto-regenerated.

There should be no user visible changes after this commit.

gdb/ChangeLog:

	* arch/aarch32.c (aarch32_create_target_description): Release
	unique_ptr returned from allocate_target_description.
	* arch/aarch64.c (aarch64_create_target_description): Likewise.
	* arch/amd64.c (amd64_create_target_description): Likewise.
	* arch/arc.c (arc_create_target_description): Likewise.
	* arch/arm.c (arm_create_target_description): Likewise.
	* arch/i386.c (i386_create_target_description): Likewise.
	* arch/riscv.c (riscv_create_target_description): Update return
	type.  Handle allocate_target_description returning a unique_ptr.
	(riscv_lookup_target_description): Update to handle unique_ptr.
	* arch/tic6x.c (tic6x_create_target_description): Release
	unique_ptr returned from allocate_target_description.

2554f6f564 gdb: give names to event loop file handlers 
Assign names to event loop file handlers.  They will be used in debug
messages when file handlers are invoked.

In GDB, each UI used to get its own unique number, until commit
cbe256847e ("Remove ui::num").  Re-introduce this field, and use it to
make a unique name for the handler.

I'm not too sure what goes on in ser-base.c, all I know is that it's
what is used when debugging remotely.  I've just named the main handler
"serial".  It would be good to have unique names there too.  For instance
when debugging with two different remote connections, we'd ideally want
the handlers to have unique names.  I didn't do it in this patch though.

	* async-event.c (initialize_async_signal_handlers): Pass name to
	add_file_handler

b60cea74de Make target_wait options use enum flags 
This changes TARGET_WNOHANG to be a member of an enum, rather than a
define, and also adds a DEF_ENUM_FLAGS_TYPE for this type.  Then, it
changes target_wait and the various target wait methods to use this
type rather than "int".

This didn't catch any bugs, but it seems like a decent cleanup
nevertheless.

I did not change deprecated_target_wait_hook, since that's only used
out-of-tree (by Insight), and there didn't seem to be a need.

I can't build some of these targets, so I modified them on a
best-effort basis.  I don't think this patch should go in before the
release branch is made.

013e3554b2 gdbserver/linux-low: use std::list to store pending signals 
Use std::list to store pending signals instead of a manually-managed
linked list.  This is a refactoring.

In the existing code, pending signals are kept in a manually-created
linked list with "prev" pointers.  A new pending signal is thus
inserted to the beginning of the list.  When consuming, GDB goes until
the end of the list, following the "prev" pointers, and processes the
final item.  With this patch, a new item is added to the end of the
list and the item at the front of the list is consumed.  In other
words, the list elements used to be stored in reverse order; with this
patch, they are stored in their order of arrival.  This causes a change
in the debug messages that print the pending signals.  Otherwise, no
behavioral change is expected.

bea571ebd7 Use construct_inferior_arguments which handles special chars 
Use the construct_inferior_arguments function instead of
stringify_argv to construct a string from the program
arguments in those places where that one is then passed
to fork_inferior (linux-low, lyn-low), since
construct_inferior_arguments properly takes care of
special characters, while stringify_argv does not.
Using construct_inferior_arguments seems "natural", since its
documentation also mentions that it "does the
same shell processing as fork_inferior".

Since construct_inferior_args has been extended to do
proper quoting for Windows shells in commit
5d60742e2d
("Fix quoting of special characters for the MinGW build.",
2012-06-12), use it for the Windows case as well.
(I could not test that case myself, though.)

Adapt handling of empty args in function 'handle_v_run'
in gdbserver/server.cc to just insert an empty string
for an empty arg, since that one is now properly handled
in 'construct_inferior_arguments' already (and inserting
a "''" string in 'handle_v_run' would otherwise
cause that one to be treated as a string literally
containing two quote characters, which
'construct_inferior_args' would preserve by adding
extra escaping).

This makes gdbserver properly handle program args containing special
characters (like spaces), e.g. (example from PR25893)

  $ gdbserver localhost:50505 myprogram "hello world"

now properly handles "hello world" as a single arg, not two separate
ones ("hello", "world").

gdbserver/ChangeLog:

	PR gdbserver/25893
	* linux-low.cc (linux_process_target::create_inferior),
	lynx-low.cc (lynx_process_target::create_inferior),
	win32-low.cc (win32_process_target::create_inferior): Use
	construct_inferior_arguments instead of stringify_argv
	to get string representation which properly escapes
	special characters.
	* server.cc (handle_v_run): Just pass empty program arg
	as such, since any further processing is now handled via
	construct_inferior_arguments.

ef0478f611 gdbserver/linux-low: start turning linux target ops into methods 
This is the beginning of a series of patches that convert the linux
low targets into classes derived from linux_process_target.  At the
end of the series we obtain a class hierarchy that looks like this:

process_stratum_target
^
|
|-- linux_process_target
    ^
    |
    |-- x86_target (defined in linux-x86-low)
    |-- aarch64_target (defined in linux-aarch64-low)
    |-- ppc_target (defined in linux-ppc-low)
    |-- ...

In several cases, linux_process_target simply forwards a target op
request to a corresponding linux_target_ops function.  For these
cases, the definition in linux_process_target will be removed and the
definition will be left to the deriving linux low target class; using
inheritance provides a nice and natural, object-oriented
simplification in these cases.

The series converts linux_target_ops into protected methods of
linux_process_target one by one.  Throughout the series, based on the
needs, static functions defined in linux-low.cc are converted to
private methods of linux_process_target as well.  This is done either
as separate patches or as integrated into a patch that convert a
particular linux_target_op into a method.

The series ends with the patch titled "gdbserver/linux-low: delete
'linux_target_ops' and 'the_low_target'".

Built and regression-tested on x86_64-linux.  The following linux low
targets have been built (but not tested) via cross-compilation:
aarch64, arm, m68k, mips, ppc, riscv, s390, sh, sparc.  The other
targets (bfin, cris, crisv32, ia64, m32r, nios2, tic6x, tile, xtensa)
were neither built nor tested.

52405d85ec gdbserver: finish turning the target ops vector into a class 
Now that 'process_stratum_target' has a single field left, namely 'pt'
of type 'process_target', and that all the requests to a
'process_stratum_target' are forwarded to 'pt', meld the
'process_target' class into 'process_stratum_target'.

This essentially means

1. All the references of the form 'the_target->pt' become 'the_target'.

2. All the uses of the name 'process_target' become
   'process_stratum_target'.

3. The platform-specific target op vectors (e.g. linux_target_ops) are
   removed and instances of their "process target" classes are used
   instead.

gdbserver/ChangeLog:
