Christopher Snowhill d7418c3b33 [Cog Audio] Rename Semaphore.h to CogSemaphore.h
This magically fixes the stupid header maps that were pulling the system
semaphore.h into Swift projects, when they shouldn't have been doing
that in the first place. This is the same reason that the FLAC library
has its assert.h renamed to FLAC_assert.h.

Christopher Snowhill 7e267f06cb [Cog Audio] Change a couple of imports
These imports needed to be changed so that Swift bridging didn't import
the system's semaphore.h instead of CogAudio's Semaphore.h, which is a
completely different thing.

Christopher Snowhill 34884d825a [Audio Processing] Move float32 converter
Move the Float32 converter to a different location, for any future plans
to support decoding audio files to common data for any other purpose.

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 4a269f05a1 [Audio Threads] Remove workgroup code
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 e334d8a017 [Audio Threads] Apply changes to workgroup handler
Apply changes to exit the thread if workgroup initialization or joining
fails, instead of attempting to continue executing the thread.

Christopher Snowhill e9230a080c [Audio Threads] Change workgroup code for safety
The changes include no longer leaving the workgroup for seeking or for
converter format changes, and also still leaving the workgroup on thread
termination if there was an error with intervals starting or finishing.

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.

Now it allocates audio workgroups per thread, using work slices like the
Apple documentation describes for asynchronous threads.

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 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.

Christopher Snowhill 637ea4efe1 Core Audio output: Rewrote major portions
After all this rewriting, down or upmixing the audio is now handled with
the lowest latency possible, meaning that toggling the HRIR option now
takes effect immediately.

Christopher Snowhill c8d2864862 Cog Audio: Enhance playback queue handler, so it always halts buffering when there are at least 30 seconds worth of buffers filled, possibly spanning multiple files.
