Following my previous commit which add support for stopping at start of
exception handler, this commit adds required gdb-mi support for this
feature.
gdb/ChangeLog:
* mi/mi-cmd-catch.c (mi_cmd_catch_handlers): New function.
* mi/mi-cmds.c (mi_cmds): Add catch-handlers command.
* mi/mi-cmds.h (mi_cmd_catch_handlers): Add external declaration.
* NEWS: Document "-catch-handlers" command.
gdb/doc/ChangeLog:
* gdb.texinfo (Ada Exception gdb/mi Catchpoints): Add
documentation for new "-catch-handlers" command.
gdb/testsuite/ChangeLog:
* gdb.ada/mi_catch_ex_hand.exp: New testcase.
* gdb.ada/mi_catch_ex_hand/foo.adb: New file.
Tested on x86_64-linux.
