Implements the main sound related primiives.

NB: I really think it would be a good cleanup to mildly rewrite the sq{plat}Sound.c files to NOT refer directly back to the VM -- TPR.

	primitiveSoundAvailableSpace Returns the number of sample frames of available sound output buffer space.
	primitiveSoundGetRecordingSampleRate Return a float representing the actual sampling rate during recording. Fail if not currently recording.
	primitiveSoundGetVolume Set the sound input recording level.
	primitiveSoundInsertSamples:from:leadTime: Insert a buffer's worth of sound samples into the currently playing buffer. Used to make a sound start playing as quickly as possible. The new sound is mixed with the previously buffered sampled.
	primitiveSoundPlaySamples:from:startingAt: Output a buffer's worth of sound samples.
	primitiveSoundPlaySilence Output a buffer's worth of silence. Returns the number of sample frames played.
	primitiveSoundRecordSamplesInto:startingAt: Record a buffer's worth of 16-bit sound samples.
	primitiveSoundSetLeftVolume:rightVolume: Set the sound input recording level.
	primitiveSoundSetRecordLevel: Set the sound input recording level.
	primitiveSoundStartBufferSize:rate:stereo: Start the double-buffered sound output with the given buffer size, sample rate, and stereo flag.
	primitiveSoundStartBufferSize:rate:stereo:semaIndex: Start the double-buffered sound output with the given buffer size, sample rate, stereo flag, and semaphore index.
	primitiveSoundStartRecordingDesiredSampleRate:stereo:semaIndex: Start recording sound with the given parameters.
	primitiveSoundStop Stop double-buffered sound output.
	primitiveSoundStopRecording Stop recording sound.

	headerFile If there is a single intrinsic header file to be associated with the plugin, here is where you want to put it. It will be generated and included automatically.
