Merge remote-tracking branch 'qatar/master'

* qatar/master:
  snow: split snow in snowdec and snowenc
  tiffenc: deprecate using compression_level
  swscale: fix failing fate tests.
  swscale: add support for planar RGB input.
  h264: add support for decoding planar RGB images.
  Clean up swscale pixfmt macros using av_pix_fmt_descriptors[].
  pixfmt: add planar RGB formats.
