gst/gstevent.*: fix #320529 - clean up new_segment API and structure.
Original commit message from CVS: * gst/gstevent.c: (gst_event_new_new_segment), (gst_event_parse_new_segment): * gst/gstevent.h: fix #320529 - clean up new_segment API and structure. Let's hope everyone was using the methods, and not the structure.
