Don't unlock the pulseaudio mainloop when mixing
...
Lock contention could cause a lengthy delay between mixing and writing the
audio. There shouldn't be any risk of dead-locking as the device lock should
never be held when the mainloop gets locked.

These functions should not fail, but there seem to be bugs that cause them to
sometimes. We're flexible enough to handle almost anything it throws back at us
though, so anything is better than nothing here.

Allow PulseAudio to spawn a server by default
...
Since only one backend is used at a time now, the issues with device ownership
aren't really prevelant anymore. An application that tries to open all
enumerated devices won't run into the problem of spawning a server and end up
preventing other backend devices from working.

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.

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.

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.
