Tell the Jack server to call @a freewheel_callback
whenever we enter or leave "freewheel" mode, passing @a
arg as the second argument. The first argument to the
callback will be non-zero if JACK is entering freewheel
mode, and zero otherwise.
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.
