gst/qtdemux/qtdemux.*: Handle stss boxes so we can mark and find keyframes.
Original commit message from CVS: * gst/qtdemux/qtdemux.c: (gst_qtdemux_init), (gst_qtdemux_push_event), (gst_qtdemux_go_back), (gst_qtdemux_perform_seek), (gst_qtdemux_do_seek), (gst_qtdemux_handle_src_event), (plugin_init), (gst_qtdemux_change_state), (gst_qtdemux_loop_state_movie), (gst_qtdemux_loop), (gst_qtdemux_chain), (qtdemux_sink_activate_pull), (gst_qtdemux_add_stream), (qtdemux_parse), (qtdemux_parse_tree), (qtdemux_parse_trak), (qtdemux_parse_udta), (qtdemux_tag_add_str), (qtdemux_tag_add_num), (qtdemux_tag_add_gnre), (gst_qtdemux_handle_esds): * gst/qtdemux/qtdemux.h: Handle stss boxes so we can mark and find keyframes. Implement correct accurate and keyframe seeking. Use _DEBUG_OBJECT when possible.
