I have had a look at the above, and AFAICS (a.o.):
- the fragmented moov size (property) added early on is not really used/useful
- buffer collection is forced to stay on a single pad for a certain
fragment-duration.  Depending on this duration, and the settings of upstream
queues, there is a risk that dataflow deadlocks.

In particular, it is preferable not to introduce the latter risk in the muxer,
and it can likely be avoided using qtmux-in-house buffering (either in memory
or file, for which code is already in place in some or the other form).

As such, going forward on this qtmux feature, I'll be using a fair share of the
provided branch, but reorganize/modify to address above concerns and some other
matters of consistent qtmux-style.  Also, some commits seem not directly
related to fragmented support as such (which is not to say they are without
merit).
