2018-04-15avcodec/aac_ac3_parser: account for data already in the parsing bufferHendrik Leppkes
If a frame starts very close to a packet boundary, the start code may already have been added to the parsing buffer, indicated by a small negative value of "i", while the header is still being tracked in the "state" variable. Reduce the remaining size accordingly, otherwise trying to find the next frame could skip over the frame header and lump two frames together as one.

2017-04-27aac_ac3_parser: Drop in-parser downmix functionalityVittorio Giovara
request_channel_layout is a decoder option and it makes no sense to have it in a parser. This feature was needed in the past when the decoder was allowed to reuse the avctx from the demuxer. Nowadays the decoder receives only the parameters from it, already containing the real channel layout (and the correct request_channel_layout option). After initialization the decoder overwrites the channel layout with the downmixed one that is actually output, so there is no need to preserve this functionality in the parser.
