* DSP: Implement Pipe 2
Pipe 2 is a DSP pipe that is used to initialize both the DSP hardware (the
application signals to the DSP to initialize) and the application (the DSP
provides the memory location of structures in the shared memory region).
* AudioCore: Implement codecs (DecodeADPCM, DecodePCM8, DecodePCM16)
* DSP Pipes: Implement as FIFO
* AudioCore: File structure
* AudioCore: More structure
* AudioCore: Buffer management
* DSP/Source: Reorganise Source's AdvanceFrame.
* Audio Output
* lolidk
* huh?
* interp
* More interp stuff
* oops
* Zero State
* Don't mix Source frame if it's not enabled
* DSP: Forgot to zero a buffer, adjusted thread synchronisation, adjusted format spec for buffers
* asdf
* Get it to compile and tweak stretching a bit.
* revert stretch test
* deleted accidental partial catch submodule commit
* new audio stretching algorithm
* update .gitmodule
* fix OS X build
* remove getopt from rubberband
* #include <stddef> to audio_core.h
* typo
* -framework Accelerate
* OptionTransientsSmooth -> OptionTransientsCrisp
* tweak stretch tempo smoothing coefficient. also switch back to smooth.
* tweak mroe
* remove printf
* sola
* #include <cmath>
* VERY QUICK MERGE TO GET IT WORKING DOESN'T ACTIVATE AUDIO FILTERS
* Reminder to self
* fix comparison
* common/thread: Correct code style
* Thread: Make Barrier reusable
* fix threading synchonisation code
* add profiling code
* print error to console when audio clips
* fix metallic sound
* reduce logspam
