3131104595 Filter out a couple pulseaudio stream properties by setting them to 0-length data 
It seems Qt/Phonon will globally set media.role and phonon.streamid properties,
causing them to apply even to our streams if they happen to be loaded in the
same process. This is particularly a problem because media.role gets set to
"event", preventing the streams from showing in pavucontrol.

fe6e532c87 Use a separate backend callback to start playback of the device 
This allows us to properly update the ALCdevice and its resources with the new
parameters before starting playback, instead of expecting the mixer to block
and wait after it has begun.

This also lets us avoid holding the device lock while resetting and starting
the device, which helps prevent lock inversion on some backends (ie, one thread
locking A then B, and another thread locking B then A), ultimately allowing
certain backends to asynchronously update the ALCdevice without risk of lockup.
Capture still has issues here, however.

01d942628b Set prebuf to the expected buffer size 
This is to make sure the stream starts even if PulseAudio increases tlength.

346f1ac293 Don't allow the PulseAudio stream to move 
Since the device specifier isn't updated to reflect the change, it's best to
not allow it to move. This should be fixed eventually.

75679c959a Don't update the device update parameters when PulseAudio does an async buffer update 
It risks a deadlock, and though the UpdateSize won't change, we'll still fill
as much of the buffer as we can up to a multiple of it
