Original commit message from CVS:
* gst/asfdemux/asfheaders.h:
* gst/asfdemux/gstasfdemux.c: (gst_asf_demux_get_obj_stream),
(gst_asf_demux_process_stream),
(gst_asf_demux_process_language_list),
(gst_asf_demux_process_ext_stream_props),
(gst_asf_demux_process_queued_extended_stream_objects),
(gst_asf_demux_process_object), (gst_asf_demux_change_state):
* gst/asfdemux/gstasfdemux.h:
Parse extended stream properties objects and stream objects
hidden inside them (but delay creation of the appropriate
pads until after all the 'normal' stream objects have been
dealt with) (#343763). Also parse language list object.
