Original commit message from CVS:
* ext/ogg/gstoggmux.c: (gst_ogg_mux_sink_event),
(gst_ogg_mux_request_new_pad):
* ext/ogg/gstoggmux.h:
Don't pretend to support NEWSEGMENT events, instead override the
GstCollectPads event function to return FALSE on NEWSEGMENT events
and do the normal work for other events.
This prevents elements like flacenc to seek to the start and rewrite
some data which then results in a broken Ogg packet.
