Subject: ext/dv/gstdvdec.c: Reset segment info on flush.

Original commit message from CVS:
* ext/dv/gstdvdec.c: (gst_dvdec_class_init), (gst_dvdec_init),
(gst_dvdec_finalize), (gst_dvdec_sink_event),
(gst_dvdec_change_state):
Reset segment info on flush.
Alloc segment in _init, free in _finalize.
* ext/dv/gstdvdemux.c: (gst_dvdemux_handle_pull_seek):
Don't send segments twice.
