Partial packet reads were needed because the video/audio parsers were working on top of them. So it could happen that a parser read a part of a packet, and returned that to the decoder. With libavformat/libavcodec, packets are already parsed, and everything is much simpler. Most of the simplifications in ad_spdif could have been done earlier. Remove some other stuff as well, like the questionable slave mode start time reporting (could be replaced by proper code, but we don't bother). Remove the unused skip_audio_frame() functionality as well (it was used by old demuxers). Some functions become private to demux.c, like demux_fill_buffer(). Introduce new packet read functions, which have simpler semantics. Packets returned from them are owned by the caller, and all packets in the demux.c packet queue are considered unread. Remove special code that dropped subtitle packets with size 0. This used to be needed because it caused special cases in the old code.
