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 eb9d642192 [FreeSurround] Experimental implementation code
This is a working implementation of FreeSurround, but I can't get it to
work in the Cog code base, as the whole project crashes head over heels
if this code is inserted into the output chain.

This filter replaces the old one, and uses OpenAL Soft presets. Since

except to turn it on or off.

Christopher Snowhill e37d1d15b1 Remove unnecessary files from build and copy steps
Remove a single .inc include from CogAudio build phase, as it's included
but not compiled as Pascal like Xcode thinks. Also remove a bunch of
files from being copied into the resulting .framework and .bundle files
during link stage, as we don't need to distribute that stuff.

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 aa36e3ce10 Completely overhaul code signing practices
Redesign the code signing from the ground up. Now all bundles and their
embedded frameworks import the Shared.xcconfig file and enable its
settings, so they may be signed with Apple Development instead of sign
to run locally. This apparently isn't necessary for frameworks which are
embedded in the main app bundle directly, only for the bundles and their
frameworks.

Christopher Snowhill 7813712df3 [Audio Threads] Correctly set real time priority
I'm not sure about macOS Ventura, but stable releases of macOS, at

doing this results in an uncaught exception and a crash.

Christopher Snowhill da4630f4c5 Add a metadata loader cache
Promote the Plugin Controller source file to Objective-C++, and add a
simple data cache that holds on to requests for up to 5 seconds after
their last access, for preventing spammed requests from hitting files
over and over. This is apparently really relevant to the CUESheet reader
and its embedded CUESheet handling, as that tends to reread the same
file over and over as it populates the playlist with tracks. The nested
reader can also lead to repeated reading even on files without CUESheets
embedded.

Christopher Snowhill 51e9648865 Improve libsoxr setup
Replace libsoxr dylib with a static library, and also build the two
architectures separately, to allow for platform-specific optimizations
to be employed for both. This also reduces the size of the CogAudio
framework by a few hundred kilobytes, as we eliminate unused code paths
better this way.

Christopher Snowhill e7b78085ca New feature: Implemented headphone virtualization
This new virtualizer uses the Accelerate framework to process samples.
I've bundled a HeSuVi impulse for now, and will add an option to select
an impulse in the future. It will validate the selection before sending
it to the actual filter, which outright fails if it receives invalid
input. Impulses will be supported in any arbitrary format that Cog
supports, but let's not go too hog wild, it requires HeSuVi 14 channel
presets.
