Original commit message from CVS:
* gst/qtdemux/qtdemux.c: (gst_qtdemux_loop_header),
(gst_qtdemux_add_stream), (qtdemux_parse), (qtdemux_type_get),
(qtdemux_dump_stsz), (qtdemux_dump_stco), (qtdemux_dump_co64),
(qtdemux_dump_unknown), (qtdemux_parse_tree), (qtdemux_parse_udta),
(qtdemux_tag_add), (get_size), (gst_qtdemux_handle_esds): More qtdemux
hackage -- parse a lot more atoms, extract a few tags.  One might even
mistake this for tag support.  Maybe it is.
