* PortAudio driver: do not specify frames per buffer, let PA decide
* Remove old non-RubberBand time stretcher -- it doesn't work with varying
buffer sizes such as the PA driver may now be using
* Rewrite getCurrentPlayingFrame for greater correctness when using long
buffer sizes (interpolating according to audio stream timestamp)
* Several changes to make the timestretch management RT safe(r)
