Sample rate changes will now occur on exact sample boundaries, like they
are supposed to. Also, FreeSurround accounts for its output latency.

The DSPs should not be deinitialized from another thread, possibly while
they are currently processing.

This is the code that actually needs to be added to make it process
audio. This insertion makes the whole app crash when processing audio at
all. Weirdly, simply reverting these two files makes the audio code work
again. I can't explain it.
Also, commenting out CMAudioFormatDescriptionCreate makes it work, too.
There's something weird going on with that function.

This filter replaces the old one, and uses OpenAL Soft presets. Since
there aren't that many of those, I've left off configuration for now,
except to turn it on or off.

Stop output when requested, except on natural completion of the last
track in the play queue. Also fix deadlocks with stopping and
restarting.

The output now uses AVSampleBufferAudioRenderer to play all formats, and
uses that to resample. It also supports Spatial Audio on macOS 12.0 or
newer. Note that there are some outstanding bugs with Spatial Audio
support. Namely that it appears to be limited to only 192 kHz at mono or
stereo, or 352800 Hz at surround configurations. This breaks DSD64
playback at stereo formats, as well as possibly other things. This is
entirely an Apple bug. I have reported it to Apple with reference code
FB10441301 for reference, in case anyone else wants to complain that it
isn't fixed.
