Protect pad exposure with a preroll lock to avoid situations
where no-more-pads is fired more than once, or fired just before
the last pad is actually added.
Send segment updates to the audio and subpicture pads more frequently,
but less often to the video pad, where timestamps appear less often.
This helps with gap filling on some DVDs.
When creating a filler audio buffer in rsnaudiomunge, generate
a bit more, as audio sinks don't seem to preroll otherwise. This
needs a better algorithm in general, to intelligently fill the
gap, rather than hard-coding a value.
Make timed still frames work better by extending the current segment
when needed, and restarting the still sequence with the correct
remaining duration when the wait it interrupted by activation of a
highlight NAV packet.
The part number reported while in a menu doesn't reflect the selected
menu, so it's pointless to use it to report which menu we're in (Audio,
Angle etc). Just report "DVD Menu" in the title tag instead.
The logical audio and subpicture stream number doesn't always correspond
with the physical substream it is coming from. When configuring the demuxer
pads, use the mapping table provided in each PGC to get the layout and
ensure the demuxer creates the correct pads.
modplug's sndfile.h conflicts with libsndfile's sndfile.h, so
we'll access it directly using modplug/sndfile.h. Fixes#573849

No need to unref buffers if pad_push returns something non-FLOW_OK.
In fact, this will cause assertions or crashes. However, we do need
to unref the input buffer whenever we don't pass it downstream. Also,
a non-OK flow return is not an error, so don't post error messages on
the bus - the pipeline may just be shutting down. Miscellaneous other
clean-ups and crack removal. Plenty of work left for those who feel
like it.
When sending the stream change message(s) to the demuxer, also include the
logical stream id along with the physical ID, so that the demuxer can remap
logical->physical MPEG stream ID.
Handle the new DVD commands, so that we can handle commands from a player
to change angle, jump to menus etc. Use the new GstNavigation event parsing
functions, instead of hand-rolled stuff.
Send GstNavigation notification messages when the mouse enters a button
or leaves it, so UI can turn the mouse cursor to a hand icon.
Make the highlights re-appear correctly when jumping back into menus
by making sure to set the flushing_seek flag for user-action initiated
seeks.
Fiddle some debug related to tracking down the issue.
Add a workaround for an apparent libdvdnav bug where it loses nav packets
during multiangle titles, and add some keypress bindings to switch the angle.
