Updated seek example.
Original commit message from CVS:
* docs/libs/tmpl/gstringbuffer.sgml:
* examples/seeking/seek.c: (make_vorbis_theora_pipeline),
(query_rates), (query_positions_elems), (query_positions_pads),
(update_scale), (do_seek):
Updated seek example.

(gst_ogg_pad_submit_page), (gst_ogg_demux_activate_chain),
(gst_ogg_demux_find_chains), (gst_ogg_demux_send_event),
(gst_ogg_demux_loop):
Push out correct discont values.
