Merge remote-tracking branch 'qatar/master'

* qatar/master:
  id3v2: fix doxy comment - 'machine byte order' makes no sense on char arrays
  VC1: restore mistakenly removed code
  twinvq: check output buffer size before decoding
  twinvq: return an error when the packet size is too small
  lavf: export some forgotten symbols with non-av prefixes.
  swscale: update altivec yuv2planeX asm to new per-plane API.
  swscale: make yuv2yuvX_10_sse2/avx 8/9/16-bits aware.
  yuv2planeX10 SIMD
  swscale: decide whether to use yuv2plane1/X on a per-plane basis.
  swscale: reintroduce full precision in 16-bit output.
  Split up yuv2yuvX functions
  Split out yuv2yuv1 luma and chroma in order to make them generic DSP functions
  lavc: replace references to deprecated AVCodecContext.error_recognition to use AVCodecContext.err_recognition
  lavc: translate non-flag-based er options into flag-based ef options at codec open
  add -err_filter AVOptions to access flag-based error recognition
  h264_weight: initialize "height" function argument properly.
  presets: spelling error in libvpx 1080p50_60
  avplay: fix fullscreen behaviour with SDL 1.2.14 on Mac OS X
