  vc1: re-initialize tables after width/height change.
  APIchanges: fill-in git commit hash for av_get_bytes_per_sample() addition
  samplefmt: add av_get_bytes_per_sample()
  iirfilter: fix biquad filter coefficients.
  swscale: remove duplicate conversion routine in swScale().
  swscale: add yuv2planar/packed function typedefs.
  swscale: integrate yuv2nv12X_C into yuv2yuvX() function pointers.
  swscale: reindent x86 init code.
