* commit '50a1c66cf6ab7eb683daaa9e2da3869fa3a54609': ac3_parser: add a public function for parsing the data required by the demuxer avpriv_ac3_parse_header() is left in place but without the GetBitContext parameter, as the mov muxer requires a lot more fields than just bitstream_id and frame_size from the AC3HeaderInfo struct.
