0db9730a50 Add an option to allow PulseAudio to move streams 
This could be made the default, if there's a safe way to update the AL device
specifier.

92827cc467 Clamp the ALSA buffer time between min and max if setting near fails 
It seems there's some bugs with snd_pcm_hw_params_set_buffer_time_near that
cause it to return "invalid argument" despite a valid nearby buffer time being
available. Clamping the buffer time seems to mitigate the issue a bit.

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.

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.
