* commit 'cbcd497f384f0f8ef3f76f85b29b644b900d6b9f':
  adxdec: use planar sample format
  adpcmdec: use planar sample format for adpcm_thp
  adpcmdec: use planar sample format for adpcm_ea_xas
  adpcmdec: use planar sample format for adpcm_ea_r1/r2/r3
  adpcmdec: use planar sample format for adpcm_xa
  adpcmdec: use planar sample format for adpcm_ima_ws for vqa version 3
  adpcmdec: use planar sample format for adpcm_4xm
  adpcmdec: use planar sample format for adpcm_ima_wav
  adpcmdec: use planar sample format for adpcm_ima_qt
  pcmdec: use planar sample format for pcm_lxf
  mace: use planar sample format
  atrac1: use planar sample format
  build: non-x86: Only compile mpegvideo optimizations when necessary
  rtpdec_mpeg4: au_headers is a single array, simple av_free is enough
  avcodec: free extended_data instead address of it
  fate: Add tests of the ff_make_absolute_url function
  url: Handle relative urls starting with two slashes
  url: Handle relative urls being just a new query string
  url: Don't treat slashes in query parameters as directory separators
