Wim Taymans 8666c1597d gst/gstsegment.c: Added more documentation. 
Original commit message from CVS:
* gst/gstsegment.c: (gst_segment_init),
(gst_segment_set_last_stop), (gst_segment_set_seek),
(gst_segment_set_newsegment), (gst_segment_to_stream_time),
(gst_segment_to_running_time):
Added more documentation.
Make sure the last_pos value is updated properly.
Make sure to_stream_time and to_running_time don't
operate on wrong values.

* tests/check/gst/gstsegment.c: (GST_START_TEST):
Update check.
