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.

Add a method to calculate gains given a sound point and its half-width, and use it for reverb
...
The half-width ranges from 0 to pi, and essentially specifies the coverage area
around the listener. At 0, it's an infinitely small point sound and behaves
like a usual panning sound. At pi/2 it covers half the area, and at pi it
covers the whole area.
