Tom Tromey 35c61a1dd5 Small event ownership clean up in Python layer
It seems cleaner to me for functions like create_thread_event_object,
which pass object ownership to their callers, to directly return a
gdb_ref<>.  This way the ownership transfer is part of the API.  This
patch makes this change.
