Move ppapi audio interface out of dev, but

for this CL, also keep the old dev interface
around temporarily, to avoid tree breakage.
Add sample_rate to RecommendSampleFrameCount() to the
non-dev audio interface. Currently ignored, but useful
information to use when we need to refine RecommendSampleFrameCount()
