core, demux, vd_ffmpeg: pass side data from demux_lavf to vd_ffmpeg Pass the libavformat packet side_data field from demux_lavf to vd_ffmpeg. Libavcodec/libavformat use this field for palette data, and passing it is required for the playback of some paletted video codecs. The implementation works by giving vd_ffmpeg a copy of the struct demux_packet used to store the video packet (from which it can access the avpacket field). The definition of struct demux_packet is moved to new file demux_packet.h so that vd_ffmpeg.c can use it without including all of demuxer.h.

demux, vd_ffmpeg: fix demux keyframe flag, set AV_PKT_FLAG_KEY There was some confusion about the "flags" field in demuxer packets. Demuxers set it to either 1 or 0x10 to indicate a keyframe (and the field was not used to indicate anything else). This didn't cause visible problems because nothing read the value. Replace the "flags" field with a boolean "keyframe" field. Set AV_PKT_FLAG_KEY based on this field in packets fed to libavcodec video decoders (looks like PNG and ZeroCodec are the only ones which depend on values from demuxer; previously this was hardcoded to true for PNG). Make demux_mf set the keyframe field in every packet. This matters for PNG files now that the demuxer flag is forwarded to libavcodec. Fix logic setting the field in demux_mkv. It had probably not been updated when adding SimpleBlock support. This probably makes no difference for any current practical use.
