If the resampling API is not going to be separated out for quite some
time, I can extend af_resample to wrap the sampling rate conversions in
libavcodec/resample2.c

Then we can use the lavfi audio framework to replace the post processing
steps in ffmpeg.c similar to ow the lavfi video filters replace the video
post processing steps in ffmpeg.c

Please let me know if we want this now.
