jack: handle port registration events for jack clients

Browse source 
The jack client API expects the ports to unregister when a jack client is
deactivated and to register when it is activated. We use pause/resume
for deactivate/activate and don't really destroy the ports.

Track the state of the node (client) and emit port registration when it
changes state. Also make sure we don't emit a port registration when the
node is deactivated.

Fixes #3260
