Merge remote-tracking branch 'qatar/master'

* qatar/master: (27 commits)
  asfdec: add side data to ASFStream packet instead of output packet.
  idroqdec: set AVFMTCTX_NOHEADER and create streams as they occur.
  nellymoserdec: Indicate that the decoder can handle changed parameters
  libavcodec: Apply parameter change side data when decoding audio
  flvdec: Add param change side data if the sample rate or channels have changed
  libavformat: Add a utility function for adding parameter change side data
  libavcodec: Define a side data type for parameter changes
  aacdec: Handle new extradata passed as side data
  flvdec: Export new AAC/H.264 extradata as side data on the next packet
  libavcodec: Define a side data type for new extradata
  flacdec: skip all track indices at once instead of looping.
  mxf: Add PictureEssenceCoding UL for V210.
  mxfdec: consider QuantizationBits between 17 and 24 to be pcm_s24*
  mxfenc: Add support for MPEG-2 MP@HL-14 in mxf container.
  mxf: H.264/MPEG-4 AVC Intra support
  configure: Show whether the safe bitstream reader is enabled
  x86: Tighten register constraints for decode_significance*_x86.
  Replace Subversion revisions in comments by Git hashes.
  h264_cabac: synchronize decode_significance_*_x86 conditionals
  w32threads: wait for the waked thread in pthread_cond_signal.
