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.
