* Streamline offset <=> entry handling. Historically the demuxer didn't support information from index tables and stored the discovered information in an array per track. When index table support was added, a parallel system was setup for that relationship. This commit unifies this into one system with the `find_edit_entry()` and `find_entry_for_offset()` functions. * By extension, per-track offset entry tables are only created/used if no index table is present for those tracks. * Use index table information as-is. The index table system from MXF is quite complex and there are various ways to use the information contained within. Instead of converting that information we store the data from the tables as-is and extract the needed information when needed. * Handle index tables without entries (i.e. all content package units are of the same size). * Allow collecting index table segments as we go instead of only once if a random-index-pack is present. This also improves support of some files in push-mode. * When searching for keyframe entries, use the keyframe_offset if present (speeds up searching). * For interleaved content (i.e. several tracks in the sample essence container), we use a system to be able to identify the position of each track in the delta entries of index tables. * Handle temporal offset only on tracks which *do* need it (as specified in the delta entries of the index tables). If present, those offsets are stored in a pre-processed table which allows computing PTS from DTS with a simple offset. * Add a quirk for files which are known to be have wrongly stored temporal offsets. * Overall opens the way to handle more types of MXF files, especially those with non-frame-wrapping.
