Fix memory leaks in asyncio ProactorEventLoop on overlapped operation failures. Changes: * Implement the tp_traverse slot in the _overlapped.Overlapped type to help to break reference cycles and identify referrers in the garbage collector. * Always clear overlapped on failure: not only set type to TYPE_NOT_STARTED, but release also resources. (cherry picked from commit 5485085) Co-authored-by: Victor Stinner <vstinner@redhat.com>
