ac4fc4026c Add a device method to retrieve the active latency
This is effectively the time until the next update will be heard by the user,
or the closest approximation thereof, in nanoseconds.

f42f655ea9 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.

785f52aa29 Only try float32 with DSound when specifically requested
Some hardware drivers seem to have a bug where a buffer descriptor with a
32-bit float sample type ends up creating a non-float32 buffer.

051195a991 Avoid failing if ALSA can't set a buffer or period time near to our request
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.

90ca6675c2 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.

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.

74e128bd0f Fix ComputeAngleGains
The old code would improperly handle speakers just inside or outside the
coverage area if it had to be inverted. It also didn't properly handle when
only one speaker was outside of the covered area.

611bd0b2d3 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.
