[RFA] gdb-events.sh: Add clear_gdb_event_hooks

[Keith Seitz <keiths@redhat.com>]

Hi,

More fallout of my MI work: when switching interpreters, we'll need to be 
able to clear all hooks and event handlers so that when the new 
interpreter's hooks/event handlers are installed, we don't leave the old 
ones lying about.

Ok?
Keith
