In that sense, *_pop_any() suites better than *_pop_one(). Since at it, touch up the function monitor_qmp_response_pop_any() a bit to let the callers pass in a QMPResponse struct instead of returning a struct. Change the return value to boolean to mark whether we have popped a valid response instead.
