pulse: improve stream suspended state handling

Browse source 
Only send out SUSPENDED event when there is a change in the suspended
state. This avoids sending out unsuspend events when we simply uncork.

Implement the fail_on_suspend flag for capture and playback streams.
Instead of suspending those streams, we need to kill them.
