1d506c26d9 Update copyright year range in header of all files managed by GDB
This commit is the result of the following actions:

  - Running gdb/copyright.py to update all of the copyright headers to
    include 2024,

  - Manually updating a few files the copyright.py script told me to
    update, these files had copyright headers embedded within the
    file,

  - Regenerating gdbsupport/Makefile.in to refresh it's copyright
    date,

  - Using grep to find other files that still mentioned 2023.  If
    these files were updated last year from 2022 to 2023 then I've
    updated them this year to 2024.

I'm sure I've probably missed some dates.  Feel free to fix them up as
you spot them.

70d02be7e3 gdbsupport: Replace gdb::invoke_result with std::invoke_result
Given that GDB now requires C++17, we can replace gdb::invoke_result
with std::invoke_result which is provided by <type_traits>.

This patch also removes gdbsupport/invoke-result.h as it is not used
anymore.

679a4e92b3 gdbsupport: make basic_safe_iterator::operator* return the same thing as underlying iterator
Using the following patch that removes the reference_to_pointer_iterator
from breakpoint_range, I would get:

      CXX    breakpoint.o
    /home/smarchi/src/binutils-gdb/gdb/breakpoint.c: In function ‘void breakpoint_program_space_exit(program_space*)’:
    /home/smarchi/src/binutils-gdb/gdb/breakpoint.c:3030:46: error: cannot allocate an object of abstract type ‘breakpoint’
     3030 |   for (breakpoint &b : all_breakpoints_safe ())
          |                                              ^
    In file included from /home/smarchi/src/binutils-gdb/gdb/gdbthread.h:26,
                     from /home/smarchi/src/binutils-gdb/gdb/infrun.h:21,
                     from /home/smarchi/src/binutils-gdb/gdb/gdbarch.h:28,
                     from /home/smarchi/src/binutils-gdb/gdb/arch-utils.h:23,
                     from /home/smarchi/src/binutils-gdb/gdb/breakpoint.c:21:
    /home/smarchi/src/binutils-gdb/gdb/breakpoint.h:619:8: note:   because the following virtual functions are pure within ‘breakpoint’:
      619 | struct breakpoint : public intrusive_list_node<breakpoint>
          |        ^~~~~~~~~~
    /home/smarchi/src/binutils-gdb/gdb/breakpoint.c:250:1: note:     ‘virtual breakpoint::~breakpoint()’
      250 | breakpoint::~breakpoint ()
          | ^~~~~~~~~~

This is because the operator* method of the basic_safe_iterator iterator
wrapper returns a value_type.  So, even if the method of the underlying
iterator (breakpoint_iterator, an intrusive_list iterator) returns a
`breakpoint &`, the method of the wrapper returns a `breakpoint`.

I think it would make sense for iterator wrappers such as
basic_safe_iterator to return the exact same thing as the iterator they
wrap.  At least, it fixes my problem.

12be796ca8 gdb: make all_inferiors_safe actually work
The test gdb.threads/fork-plus-threads.exp fails since 08bdefb58b
("gdb: make inferior_list use intrusive_list"):

    FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: only inferior 1 left

Looking at the log, we see that we are left with a bunch of inferiors in
the detach-on-fork=off case:

    info inferiors^M

    (gdb) FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: only inferior 1 left

when we expect to have just one.  The problem is prune_inferiors not
pruning inferiors.  And this is caused by all_inferiors_safe not
actually iterating on inferiors.  The current implementation:

  inline all_inferiors_safe_range
  all_inferiors_safe ()
  {
    return {};
  }

default-constructs an all_inferiors_safe_range, which default-constructs
an all_inferiors_safe_iterator as its m_begin field, which
default-constructs a all_inferiors_iterator.  A default-constructed
all_inferiors_iterator is an end iterator, which means we have
constructed an (end,end) all_inferiors_safe_range.

We actually need to pass down the list on which we want to iterator
(that is the inferior_list global), so that all_inferiors_iterator's
first constructor is chosen.  We also pass nullptr as the proc_target
filter.  In this case, we don't do any filtering, but if in the future
all_inferiors_safe needed to allow filtering on process target (like
all_inferiors does), we could pass down a process target pointer.

basic_safe_iterator's constructor needs to be changed to allow
constructing the wrapped iterator with multiple arguments, not just one.

With this, gdb.threads/fork-plus-threads.exp is passing once again for
me.

01027315f5 Move gdbsupport to the top level
This patch moves the gdbsupport directory to the top level.  This is
the next step in the ongoing project to move gdbserver to the top
level.

The bulk of this patch was created by "git mv gdb/gdbsupport gdbsupport".

This patch then adds a build system to gdbsupport and wires it into
the top level.  Then it changes gdb to use the top-level build.

gdbserver, on the other hand, is not yet changed.  It still does its
own build of gdbsupport.
