* generic/gdbtk-cmds.c (gdb_get_breakpoint_info): If unable
to find the requested breakpoint for lookup, check if
it is about to be deleted and return information about
that breakpoint.
(gdb_get_tracepoint_info): Ditto for tracepoints.
* generic/gdbtk-hooks.c (gdbtk_deleted_bp): New global.
(gdbtk_delete_breakpoint): Remember the deleted breakpoint
for gdb_get_breakpoint_info, in case it is called during
the event notification.
(gdbtk_delete_tracepoints): Ditto for tracepoints.
