Original commit message from CVS: * gst/mxf/mxfdemux.c: (gst_mxf_demux_reset), (gst_mxf_demux_handle_random_index_pack), (gst_mxf_demux_pull_random_index_pack), (gst_mxf_demux_loop): * gst/mxf/mxfdemux.h: * gst/mxf/mxfparse.c: (mxf_random_index_pack_parse): * gst/mxf/mxfparse.h: * gst/mxf/mxftypes.h: Implement parsing of the random index pack, which provides a seek table (including body sid) to the start of partition packs. Later this will be used for reading all index table segments of the complete file efficiently.
