fc68ed656f ALSA|Dummy: ignore port unregistration when engine is stopped

unregisters/re-registers them.

ALSA: silently ignore port unregs and silently accept registrations
Dummy: print a PBD::info message,

41caadbe7c Remove incorrect code for mingw in DummyAudioBackend::in_process_thread 
I'm assuming this section was copied from the JackAudioBackend where the
thread type is not pthread_t for mingw, but in the DummyAudioBackend it
is.
