lavf: Add an MPEG-DASH ISOFF segmenting muxer

This is mostly to serve as a reference example on how to segment
the output from the mp4 muxer, capable of writing the segment
list in four different ways:
- SegmentTemplate with SegmentTimeline
- SegmentTemplate with implicit segments
- SegmentList with individual files
- SegmentList with one single file per track, and byte ranges

The muxer is able to serve live content (with optional windowing)
or create a static segmented MPD.

In advanced cases, users will probably want to do the segmenting
in their own application code.
