Tell the JACK server to call @a graph_callback whenever the
processing graph is reordered, passing @a arg as a parameter.
All "notification events" are received in a seperated non RT thread,
the code in the supplied function does not need to be
suitable for real-time execution.
NOTE: this function cannot be called while the client is activated
(after jack_activate has been called.)
@return 0 on success, otherwise a non-zero error code
