Handle multiple breakpoint hits in Python interface:
	* python/py-bpevent.c (create_breakpoint_event_object): Rename C/Python
	variable to breakpoints.
	* python/py-stopevent.c (emit_stop_event): Return a Python tuple of
	bps instead of single breakpoint. Fix some space typos.
	* python/py-stopevent.c (create_breakpoint_event_object): Rename
	variable to breakpoints.

testsuite:
	* gdb.python/py-events.exp: Set a duplicate breakpoint and check its
	presence.
	* gdb.python/py-events.py (breakpoint_stop_handler): Browse all the
	breakpoint hits.

doc:
	* gdb.texinfo (Events In Python): New function documentation:
	gdb.BreakpointEvent.breakpoints. Indicate that
	gdb.BreakpointEvent.breakpoint is now deprecated.
