David Schleef 57b8d0d698 gst/qtdemux/qtdemux.c: Change all g_print()s to debugging. Add a bunch of consistency checks. 
Original commit message from CVS:
* gst/qtdemux/qtdemux.c: (gst_qtdemux_loop_header),
(gst_qtdemux_add_stream), (qtdemux_parse), (qtdemux_parse_tree),
(qtdemux_parse_udta), (qtdemux_tag_add), (gst_qtdemux_handle_esds):
