* qatar/master:
  pixdesc: mark pseudopaletted formats with a special flag.
  avconv: switch to avcodec_encode_video2().
  libx264: implement encode2().
  libx264: split extradata writing out of encode_nals().
  lavc: add avcodec_encode_video2() that encodes from an AVFrame -> AVPacket
  cmdutils: update copyright year to 2012.
  swscale: sign-extend integer function argument to qword on x86-64.
  x86inc: support yasm -f win64 flag also.
  h264: manually save/restore XMM registers for functions using INIT_MMX.
  x86inc: allow manual use of WIN64_SPILL_XMM.
  aacdec: Use correct speaker order for 7.1.
  aacdec: Remove incorrect comment.
  aacdec: Simplify output configuration.
  Remove Sun medialib glue code.
  dsputil: set STRIDE_ALIGN to 16 for x86 also.
  pngdsp: swap argument inversion.
