  movenc: Add a flag for indicating a discontinuous fragment

Conflicts:
	libavformat/movenc.c
Merged-by: Michael Niedermayer <michaelni@gmx.at>

This allows creating a later mp4 fragment without sequentially
writing the earlier ones before (when called from a segmenter).

Normally when writing a fragmented mp4 file sequentially, the
first timestamps of a fragment are adjusted to match the
end of the previous fragment, to make sure the timestamp is the
same, even if it is calculated as the sum of previous fragment
durations. (And for the first packet in a file, the offset of
the first packet is written using an edit list.)

When writing an individual mp4 fragment discontinuously like this
(with potentially writing the earlier fragments separately later),
there's a risk of getting a gap in the timeline if the duration
field of the last packet in the previous fragment doesn't match up
with the start time of the next fragment.

Using this requires setting -avoid_negative_ts make_non_negative
(or -avoid_negative_ts 0).

Keep the code as similar as possible across the codepaths to
ease spotting it for factorization.

Based on a patch from Michael Niedermayer <michaelni@gmx.at>.

The code currently set the information in at least 4 places, spare
some pointless loops.

Make the code in the loop a little uniform to make easier factorize
it out later.
