[PD] jack_transport improvements

[Andy Farnell]

Hi Jacob

Connects to jack server ok. Reports good connection. Can start and stop
transport.

But;

No transport notification message printed by jackd
Query doesn't work, no data on outlets

Haven't had time to debug yet, could be something my end.

a.
