public delegate BusSyncReply BusSyncHandler (Bus bus, Message message)
Handler will be invoked synchronously, when a new message has been injected into the bus.
This function is mostly used internally. Only one sync handler can be attached to a given bus.
If the handler returns DROP, it should unref the message, else the message should not be unreffed by the sync handler.
