This patch adds some breakpoint events to Python. In particular, there is a creation event that is emitted when a breakpoint is created; a modification event that is emitted when a breakpoint changes somehow; and a deletion event that is emitted when a breakpoint is deleted. In this patch, the event's payload is the breakpoint itself. I considered making a new event type to hold the breakpoint, but I didn't see a need. Still, I thought I would mention this as a spot where some other choice is possible. Built and regtested on x86-64 Fedora 23. 2016-07-13 Tom Tromey <tom@tromey.com> PR python/15620, PR python/18620: * python/py-evts.c (gdbpy_initialize_py_events): Call add_new_registry for new events. * python/py-events.h (events_object) <breakpoint_created, breakpoint_deleted, breakpoint_modified>: New fields. * python/py-breakpoint.c (gdbpy_breakpoint_created): Emit the breakpoint changed event.
