Listening on messages currently uses polling (every time mpv_wait_event() has no new events, the message buffer is polled and a message event is possibly created). Improve this situation a bit, and call the user-supplied wakeup callback. This will increase the frequency with which the wakeup callback is called, but the client is already supposed to be able to deal with this situation. Also, as before, calling mpv_wait_event() from the wakeup callback is forbidden, so the client can't read new messages from the callback directly. The wakeup pipe is written either. Since the wakeup pipe is created lazily, we can't access the pipe handle without creating a race condition or a deadlock. (This is actually very silly, since in practice the race condition won't matter, but for now let's keep it clean.)
