* qatar/master: (27 commits)
  cmdutils: use new avcodec_is_decoder/encoder() functions.
  lavc: make codec_is_decoder/encoder() public.
  lavc: deprecate AVCodecContext.sub_id.
  libcdio: add a forgotten AVClass to the private context.
  swscale: remove "cpu flags" from -sws_flags description.
  proresenc: give user a possibility to alter some encoding parameters
  vorbisenc: add output buffer overwrite protection
  libopencore-amrnbenc: fix end-of-stream handling
  ra144enc: fix end-of-stream handling
  nellymoserenc: zero any leftover packet bytes
  nellymoserenc: use proper MDCT overlap delay
  qpeg: Use bytestream2 functions to prevent buffer overreads.
  swscale: make %rep unconditional.
  vp8: convert simple loopfilter x86 assembly to use named arguments.
  vp8: convert idct x86 assembly to use named arguments.
  vp8: convert mc x86 assembly to use named arguments.
  vp8: convert loopfilter x86 assembly to use cpuflags().
  vp8: convert idct/mc x86 assembly to use cpuflags().
  swscale: remove now unnecessary hack.
  x86inc: don't "bake" stack_offset in named arguments.
