ext/resindvd/resindvdsrc.*: Schedule NAV packets and activate them with an async clock callback at the right moment. ...

Browse source 
Original commit message from CVS:
* ext/resindvd/resindvdsrc.c:
* ext/resindvd/resindvdsrc.h:
Schedule NAV packets and activate them with an async clock callback
at the right moment. This makes delayed menu highlights appear
at the correct time and fixes Back To The Future.
When outputting new segment in do_seek(), calculate our position
value properly, so we report the right time when popping in and
out of the menus.
* ext/resindvd/rsnbasesrc.c:
When handling a non-flushing seek, accumulate the segment,
rather than having every seek start from 0 and messing with sync
