event_pipe: added pipe_event enum and callbacks
Make the event_pipe (formerly main_notify) send/receive a set of events, with a callback for each one. The default event PIPE_EVENT_SIGNAL does not have a callback. It is still there for waking up the main thread, when it is waiting for the player thread.
