This rewrites the code generating the Ada exception catchpoint hit
notification for both the GDB/MI case as well as the non-MI case,
by using the relevant ui_out_* functions to generate the output.
the MI notifications for Ada exception catchpoints now include
the stop reason, and the breakpoint "disp", much like other breakpoint
events do. It also introduces a new field "exception-name" for
exception catchpoints (excluding "failed assertion catchpoints,
where we just want to know that it was a failed assertion).
