Prototype for the client supplied function that is called
whenever jackd is shutdown. Note that after server shutdown,
the client pointer is *not* deallocated by libjack,
the application is responsible to properly use jack_client_close()
to release client ressources. Warning: jack_client_close() cannot be
safely used inside the shutdown callback and has to be called outside of
the callback context.
