Merge remote branch 'qatar/master'

* qatar/master:
  ac3dec: fix processing of delta bit allocation information.
  vc1: fix fate-vc1 after previous commit.
  wmv3dec: fix playback of complex WMV3 files using simple_idct.
  make av_dup_packet() more cautious on allocation failures
  make containers pass palette change in AVPacket
  introduce side information for AVPacket

Politic commits that have not been pulled:
  Update regtest checksums after revision 6001dad.
  Replace more FFmpeg references by Libav.
  Replace references to ffmpeg-devel with libav-devel; fix roundup URL.
