6c5b2ebeac struct symtabs_and_lines -> std::vector<symtab_and_line> 
This replaces "struct symtabs_and_lines" with
std::vector<symtab_and_line> in most cases.  This removes a number of
cleanups.

In some cases, the sals objects do not own the sals they point at.
Instead they point at some sal that lives on the stack.  Typically
something like this:

  struct symtab_and_line sal;
  struct symtabs_and_lines sals;

  // fill in sal

  sals.nelts = 1;
  sals.sals = &sal;

  // use sals

Instead of switching those cases to std::vector too, such usages are
replaced by gdb::array_view<symtab_and_line> instead.  This avoids
introducing heap allocations.

c45ec17c07 A smarter linespec completer 
Continuing the theme of the explicit locations patch, this patch gets
rid of the need for quoting function names in linespec TAB completion.
To recap, when you have overloads in your program, and you want to set
a breakpoint in one of them:

 void function(int);  // set breakpoint here.
 void function(long);

 (gdb) b function(i[TAB]
 <all the symbols in the program that start with "i" are uselessly shown...>

This patch gets rid of the need for quoting by switching the linespec
completer to use the custom completion word point mechanism added in
the previous explicit location patch (extending it as needed), to
correctly determine the right completion word point.  In the case
above, we want the completer to figure out that it's completing a
function name that starts with "function(i", and it now does.

We also want the completer to know when it's potentially completing a
source file name, for:

(gdb) break source.[TAB] -> source.c:
(gdb) break source.c:  # Type line number or function name now

And we want it to know to complete label names, which it doesn't today:

(gdb) break function:lab[TAB]

etc., etc.

So what we want is for completion to grok the input string as closely
to how the linespec parser groks it.

With that in mind, the solution suggests itself - make the linespec
completer use the same parsing code as normal linespec parsing.

That's what the patch does.  The old completer is replaced by one that
reuses the actual linespec parser as much as possible.  This (ideally)
eliminate differences between what completion understands and actually
setting breakpoints understands by design.

The completer now offers sensible completion candidates depending on
which component of the linespec is being completed, source filename,
function, line number, expression, and (a new addition), labels.  For
example, when completing the function part, we now show the full name
of the method as completion candidates, instead of showing whatever
comes after what readline considered the word break character:

 (gdb) break klass::method[TAB]
 klass:method1(int)
 klass:method2()

If input is past the function, then we now offer keyword condidates:

  (gdb) b function(int) [TAB]
  if      task    thread

If input is past a keyword, we offer expression completion, which is
different from linespec completion:

  (gdb) b main if 1 + glo[TAB]
  global

(e.g., completes on types, struct data fields, etc.)

As mentioned, this teaches the linespec completer about completing
label symbols too:

  (gdb) b source.c:function:lab[TAB]

A nice convenience is that when completion uniquely matches a source
name, gdb adds the ":" automatically for you:

  (gdb) b filenam[TAB]
  (gdb) b filename.c:  # ':' auto-added, cursor right after it.

It's the little details.  :-)

I worked on this patch in parallel with writing the (big) testcase
added closer to the end of the series, which exercises many many
tricky cases around quoting and whitespace insertion placement.  In
general, I think it now all Just Works.

c6756f62e0 Rewrite/enhance explicit locations completer, parse left->right 
One of the most annoying (to me) things about GDB's completion is when
you have overloads in your program, and you want to set a breakpoint
in one of them:

 void function(int);  // set breakpoint here.
 void function(long);

 (gdb) b -f func[TAB]
 (gdb) b -f function(       # ok, gdb completed as much as possible.
 (gdb) b -f function([TAB]  # show me the overloads, please.
 <_all_ symbols in the program are shown...>

E.g., when debugging GDB, that'd be:

 (gdb) b -f function([TAB]
 (anonymous namespace)::get_global()::global  pt_insn_get_offset@plt                       scm_new_port_table_entry
 asprintf                                     pt_pkt_alloc_decoder                         scm_new_port_table_entry@plt
 asprintf@plt                                 pt_pkt_alloc_decoder@plt                     scm_out_of_range
 bt_ctf_get_char_array                        pt_pkt_sync_forward                          scm_out_of_range@plt
 bt_ctf_get_char_array@plt                    pt_pkt_sync_forward@plt                      scm_putc
 bt_ctf_get_uint64                            pwrite                                       scm_putc@plt
 bt_ctf_get_uint64@plt                        pwrite@plt                                   scm_reverse_x
 bt_ctf_iter_read_event                       PyErr_Restore                                scm_reverse_x@plt
 bt_ctf_iter_read_event@plt                   PyErr_Restore@plt                            scm_set_port_filename_x
 <snip...>

Now that's a load of completely useless completions.

The reason GDB offers those is that the completer relies on readline
figuring out the completion word point in the input line based on the
language's word break characters, which include "(".  So readline
tells the completer to complete on "", the string that is after '('.
Likewise, if you type "function(i[TAB]" to try to complete to "int",
you're out of luck.  GDB shows you all the symbols in the program that
start with "i"...  This makes sense for the expression completer, as
what you'd want to type is e.g., a global variable, say:

(gdb) print function(i[TAB]

but, it makes no sense when specifying a function name for a
breakpoint location.

To get around that limitation, users need to quote the function name,
like:

 (gdb) b -f 'function([TAB]
 function(int)      function(long)
 (gdb) b 'function(i[TAB]
 (gdb) b 'function(int)' # now completes correctly!

Note that the quoting is only necessary for completion.  Creating the
breakpoint does not require the quoting:

 (gdb) b -f function(int) [RET]
 Breakpoint 1 at ....

This patch removes this limitation.

(
Actually, it's a necessary patch, though not sufficient.  That'll
start working correctly by the end of the series.  With this patch, if try it,
you'll see:

 (gdb) b -f function(i[TAB]
 (gdb) b -f function

i.e., gdb strips everything after the "(".  That's caused by some code
in symtab.c that'll be eliminated further down the series.  These
patches are all unfortunately interrelated, which is also the reason
new tests only appear much later in the series.
But let's ignore that reality for the remainder of the description.
)

So... this patch gets rid of the need for quoting.

It does that by adding a way for a completer to control the exact
completion word point that readline should start the completion
request for, instead of letting readline try to figure it out using
the current language's word break chars array, and often failing.

In the case above, we want the completer to figure out that it's
completing a function name that starts with "function(i".  It now
does.

It took me a while to figure out a way to ask readline to "use this
exact word point", and for a while I feared that it'd be impossible
with current readline (and having to rely on master readline for core
functionality is something I'd like to avoid very much).  Eventually,
after several different attempts, I came up with what is described in
the comment above gdb_custom_word_point_brkchars in the patch.

With this patch, the handle_brkchars phase of the explicit location
completer advances the expected word point as it parses the input line
left to right, until it figures out exactly what we're completing,
instead of expecting readline to break the string using the word break
characters, and then having the completer heuristically fix up a bad
decision by parsing the input string backwards.  This allows correctly
knowning that we're completing a symbol name after -function, complete
functions without quoting, etc.

Later, we'll make use of this same mechanims to implement a proper
linespec completer that avoids need for quoting too.

c2f4122d5c Limit breakpoint re-set to the current program space 
Currently, we always re-set all locations of all breakpoints.  This
commit makes us re-set only locations of the current program space.

If we loaded symbols to a program space (e.g., "file" command or some
shared library was loaded), GDB must run through all breakpoints and
determine if any new locations need to be added to the breakpoint.
However, there's no reason to recreate locations for _other_ program
spaces, as those haven't changed.

Similarly, when we create a new inferior, through e.g., a fork, GDB
must run through all breakpoints and determine if any new locations
need to be added to the breakpoint.  There's no reason to destroy the
locations of the parent inferior and other inferiors.  We know those
won't change.

In addition to being inneficient, resetting breakpoints of inferiors
that are currently running is problematic, because:

 - some targets can't read memory while the inferior is running.

 - the inferior might exit while we're re-setting its breakpoints,
   which may confuse prologue skipping.

I went through all the places where we call breakpoint_re_set, and it
seems to me that all can be changed to only re-set locations of the
current program space.

The patch that reversed threads order in "info threads" etc. happened
to make gdb.threads/fork-plus-thread.exp expose this problem when
testing on x86/-m32.  The problem was latent and masked out by chance
by the code-cache:

 https://sourceware.org/ml/gdb-patches/2016-01/msg00213.html

Tested on x86-64 F20, native (-m64/-m32) and extended-remote
gdbserver.

Fixes the regression discussed in the url above with --target_board=unix/-m32:

 -FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: inferior 1 exited
 +PASS: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: inferior 1 exited
 -FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: no threads left (timeout)
 -FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: only inferior 1 left (the program exited)
 +PASS: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: no threads left
 +PASS: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: only inferior 1 left

87f0e72047 Explicit locations: add UI features for CLI 
This patch exposes explicit locations to the CLI user.  This enables
users to "explicitly" specify attributes of the breakpoint location
to avoid any ambiguity that might otherwise exist with linespecs.

The general syntax of explicit locations is:
-source SOURCE_FILENAME -line {+-}LINE -function FUNCTION_NAME
-label LABEL_NAME

Option names may be abbreviated, e.g., "-s SOURCE_FILENAME -li 3" and users
may use the completer with either options or values.

f00aae0f7b Explicit locations: use new location API 
This patch converts the code base to use the new struct event_location
API being introduced. This patch preserves the current functionality and
adds no new features.

The "big picture" API usage introduced by this patch may be illustrated
with a simple exmaple. Where previously developers would write:

void
my_command (char *arg, int from_tty)
{
   create_breakpoint (..., arg, ...);
   ...
}

one now uses:

void
my_command (char *arg, int from_tty)
{
   struct event_locaiton *location;
   struct cleanup *back_to;

   location = string_to_event_locaiton (&arg, ...);
   back_to = make_cleanup_delete_event_location (location);
   create_breakpoint (..., location, ...);
   do_cleanups (back_to);
}

Linespec-decoding functions (now called location-decoding) such as
decode_line_full no longer skip argument pointers over processed input.
That functionality has been moved into string_to_event_location as
demonstrated above.

0578b14e99 Expand keyword lexing intelligence in the linespec parser. 
This patch changes the heuristic the linespec lexer uses to
    detect a keyword in the input stream.

    Currently, the heuristic is: a word is a keyword if it
    1) points to a string that is a keyword
    2) is followed by a non-identifier character

    This is strictly more correct than using whitespace. For example,
    it allows constructs such as "break foo if(i == 1)". However,
    find_condition_and_thread in breakpoint.c does not support this expanded
    usage. It requires whitespace to follow the keyword.

    The proposed new heuristic is: a word is a keyword if it
    1) points to a string that is a keyword
    2) is followed by whitespace
    3) is not followed by another keyword string followed by whitespace

    This additional complexity allows constructs such as
    "break thread thread 3" and "break thread 3".  In the former case,
    the actual location is a symbol named "thread" to be set on thread #3.
    In the later case, the location is NULL, i.e., the default location,
    to be set on thread #3.

    In order to pass all the new tests added here, I've also had to add a
    new feature to parse_breakpoint_sals, which expands recognition of the
    default location to keywords other than "if", which is the only keyword
    currently permitted with the default (NULL) location, but there is no
    reason to exclude other keywords.

    Consequently, it will be possible to use "break thread 1" or
    "break task 1".

    In addition to all of this, it is now possible to remove the keyword_ok
    state from the linespec parser.

28e7fd6234 Update years in copyright notice for the GDB files. 
Two modifications:
  1. The addition of 2013 to the copyright year range for every file;
  2. The use of a single year range, instead of potentially multiple
     year ranges, as approved by the FSF.
