Switch audio synchronization from sleep() based to select() based.
Uses select() to efficiently wait for data from the renderer with a
timeout instead of using sleep() or always assuming the renderer
is ready.
Fixes glitching and / or CPU hogging when the renderer isn't ready.
BUG=179058, 180841, 260772, 269672,
TEST=Swap from 44kHz to 16kHz html5 playback, ensure glitch free.
