Change event code to use gdbpy_ref This changes the event code in the Python layer to use gdbpy_ref, simplifying the logic in many places. It also changes evpy_emit_event not to steal a reference to its argument. This is simpler to do now that gdbpy_ref is in use; it's also a reasonable cleanup in its own right. While doing this I realized that evpy_emit_event should not be calling gdbpy_print_stack (all the outermost callers do this if needed), so I removed this as well. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-threadevent.c (create_thread_event_object): Use gdbpy_ref. * python/py-stopevent.c (create_stop_event_object): Simplify.
