Merge remote-tracking branch 'qatar/master'

* qatar/master:
  mpeg12: fixed parsing in some mpeg2 streams
  Add SMPTE240M transfer characteristics flag.
  mpegts: Some additional HDMV types and reg descriptors for mpegts
  motionpixels: Clip YUV values after applying a gradient.
  jpeg: handle progressive in second field of interlaced.
  ituh263dec: Implement enough of Annex O (scalability) to fix a FPE.
  h263: more strictly forbid frame size changes with frame-mt.
  h264: additional protection against unsupported size/bitdepth changes.
  tta: prevents overflows for 32bit integers in header.
  configure: remove malloc_aligned.
  vp8: update frame size changes on thread context switches.
  snowdsp: explicitily state instruction size.
  wmall: fix reconstructing audio with uncoded channels
  WMAL cosmetics: fix indentation
  gitignore: add Win32 library suffixes
