Refs #1104. SoundTouch resync.

Syncs to 1.31.

I didn't take the MMX changes because our MMX code is faster and more versatile.
I also didn't take the SSE & the windows specific changes, we don't use the floating point sample code, and don't have a functioning windows port to test the changes with.
