Christopher Snowhill 838c0d08e8 Significantly reduce stack memory usage
Oops, there were a lot of large local buffers in use here.

Christopher Snowhill b95cb59a61 [Audio Processing] Increase thread stack size
Apparently, all these new changes with FreeSurround have pushed the
default 512KB thread stack size to the limit. And I'm not even using
stack variables, really, except for maybe the autoreleasepools.

Christopher Snowhill 8d851e5bda [Input API] Change input readAudio method
readAudio now returns an AudioChunk object directly, and all inputs have
been changed to accomodate this. Also, input and converter processing
have been altered to better work with this.

Christopher Snowhill 8af32e8d2e Replace Core Audio output with Core Media runtime
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.

Christopher Snowhill 1c36869e57 [Audio Threads] Remove unused code
This code turned out to be somewhat of a mistake to employ, so it's now
being removed, and shall not be re-added, as it doesn't really work.

As it doesn't seem to work properly on Intel machines, anyway. It just
leads to pointless crashes, and doesn't seem to serve any purpose.

Christopher Snowhill 3156aad9e1 [Audio Threads] Restrict workgroup use to macOS 12
Restrict the use of workgroup joining and workgroup intervals to macOS
Monterey or newer, as it seems the way I use it, it's completely broken
on macOS Big Sur, which was the original minimum target for the API.

Christopher Snowhill 6bd0bf1dc5 [Audio Threads] Set realtime priority on old OS
Set baseline real-time priority for audio threads even on old macOS,
since that API is available there. Only set it once, and do not attempt
again if it fails, only once per thread.

Christopher Snowhill 7813712df3 [Audio Threads] Correctly set real time priority
I'm not sure about macOS Ventura, but stable releases of macOS, at
least on Intel, require that threads joining Audio Interval
workgroups already be set to run as real-time before joining. Not
doing this results in an uncaught exception and a crash.

Christopher Snowhill 477feaab1d Now properly supports sample format changing
Sample format can now change dynamically at play time, and the player
will resample it as necessary, extrapolating edges between changes to
reduce the potential for gaps.

Currently supported formats for this:

- FLAC
- Ogg Vorbis
- Any format supported by FFmpeg, such as MP3 or AAC

Christopher Snowhill acb1dd75d3 Cog Audio: Fix memory leaks with new buffering
By applying copious amounts of autorelease pools, memory is freed in a
timely manner. Prior to this, buffer objects were freed, but not being
released, and thus accumulating in memory indefinitely, as the original
threads and functions had autorelease pools that scoped the entire
thread, rather than individual function blocks that utilized the new
buffering system. This fixes memory growth caused by playback.

Christopher Snowhill 62edb39761 Cog Audio: Major rewrite of audio buffering
Rewrite attempt number two. Now using array lists of audio chunks, with
each chunk having its format and optionally losslessness stashed along
with it. This replaces the old virtual ring buffer method. As a result
of this, the HRIR toggle now works instantaneously.
