* gst/mpegstream/gstdvddemux.c (gst_dvd_demux_handle_dvd_event):
Use the new "audio-shutdown" and "audio-restart" DVD events
instead of the "spu-still-frame" event to shutdown and restart
the audio pipeline.

* gst/mpegstream/gstmpegparse.c (gst_mpeg_parse_adjust_ts):
Check for cases where the segment-based adjustment calculation
would produce negative values (which result in an overflow) and
return GST_CLOCK_TIME_NONE instead.

* gst/mpegstream/gstdvddemux.h:
* gst/mpegstream/gstdvddemux.c (gst_dvd_demux_init)
(gst_dvd_demux_process_event, gst_dvd_demux_send_subbuffer):
Add a mechanism to discard audio buffers with timestamps outside
the currently set segment. This was causing (sometimes serious)
synchronization problems after seeking in DVDs with LPCM audio,
since VOBUs usually contain audio material that lies outside the
timestamp range specified by the header.
