* 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.
