ee4a1c63da gdb.ada/info_exc.exp,mi_exc_info.exp: Use more unique exception name.
In the case where the GNAT runtime was built with full debugging info,
several of the exceptions defined there might have a name contain
the word "global". To make this less likely, this patch renames
the exception name, replacing "Global" by "Global_GDB". It still
keeps the exeption name relatively short, while it is unlikely that
the GNAT runtime has an exception whose name explicitly mentions GDB,
and even less likely that it contains "Global_GDB".

gdb/testsuite/ChangeLog:

        * info_exc/const.ads (Aint_Global_GDB_E): Renames Aint_Global_E.
        * info_exc/foo.adb: Adjust to new exception name.
        * info_exc.exp: Adjust after exception renaming in const.ads.
        Update "info exception global" test to test "info exceptions
        global_gdb" instead.

        * mi_exc_info/const.ads (Aint_Global_GDB_E): Renames Aint_Global_E.
        * mi_exc_info/foo.adb (Adjust to new exception name.
        * mi_exc_info.exp: Adjust after exception renaming in const.ads.
        Update "-info-ada-exceptions global" test to test
        "-info-ada-exceptions global_gdb" instead.

778865d3e2 Add command to list Ada exceptions
This patch adds a new command "info exceptions" whose purpose is to
provide the list of exceptions currently defined in the inferior.
The usage is:

    (gdb) info exceptions [REGEXP]

Without argument, the command lists all exceptions.  Otherwise,
only those whose name match REGEXP are listed.

For instance:

    (gdb) info exceptions
    All defined Ada exceptions:
    constraint_error: 0x613dc0
    program_error: 0x613d40
    storage_error: 0x613d00
    tasking_error: 0x613cc0
    global_exceptions.a_global_exception: 0x613a80
    global_exceptions.a_private_exception: 0x613ac0

The name of the command, as well as its output is part of a legacy
I inherited long ago. It's output being parsed by frontends such as
GPS, I cannot easily change it. Same for the command name.

The implementation is mostly self-contained, and is written in a way
that should make it easy to implement the GDB/MI equivalent. The
careful reviewer will notice that the code added in ada-lang.h could
normally be made private inside ada-lang.c.  But these will be used
by the GDB/MI implementation.  Rather than making those private now,
only to move them later, I've made them public right away.

gdb/ChangeLog:

        * ada-lang.h: #include "vec.h".
        (struct ada_exc_info): New.
        (ada_exc_info): New typedef.
        (DEF_VEC_O(ada_exc_info)): New vector.
        (ada_exceptions_list): Add declaration.
        * ada-lang.c (ada_is_exception_sym)
        (ada_is_non_standard_exception_sym, compare_ada_exception_info)
        (sort_remove_dups_ada_exceptions_list)
        (ada_exc_search_name_matches, ada_add_standard_exceptions)
        (ada_add_exceptions_from_frame, ada_add_global_exceptions)
        (ada_exceptions_list_1, ada_exceptions_list)
        (info_exceptions_command): New function.
        (_initialize_ada_language): Add "info exception" command.

gdb/testsuite/ChangeLog:

        * gdb.ada/info_exc: New testcase.
