It works!  I'm happy with this solution ... wish you'd mentioned it a while ago
;-) ... would you be willing to submit a patch?  If not, I could, but I think
you would do a better job of understanding any side effects, etc.

Thanks for your comments about fast/simple vs. generic/complicated code ... I
tried using GArray to make the bitmasks extendable ... and of course it blew up
to be bigger than I would have liked, so I'm happy you figured out another way.

I'm still wondering how to use newsegments in a more intelligent way than I
have, but I'm completely baffled by my use case of a live source with
non-predictable frame time/duration, AND trying to minimize latency ... the
"brain-dead" approach in my sparsesegments plugin works for me (and it does
wait for the first frame before inserting the far-in-the-future newsegment, so
header is complete), but please let me know if you have a better suggestion.
