503e5e9db5 libswresample: support directly converting sampleformats and packed/planar in a single pass. 
Previously a intermediate planar format was used when both input and output where packed.

b5875b9111 Add libswresample. 
Similar to libswscale this does resampling and format convertion, just for audio
instead of video.
changing sampling rate, sample formats, channel layouts and sample packing all
in one with a very simple public interface.
