This patch is based on the stream assignment code in webmdashenc.
Additional changes:
* Default to one AdaptationSet per stream
Previously all mapped streams of a media type (video, audio) where assigned
to a single AdaptationSet. Using the DASH live profile it is mandatory, that
the segments of all representations are aligned, which is currently not
enforced. This leads to problems when using video streams with different
key frame intervals. So to play safe, default to one AdaptationSet per
stream,
unless overwritten by explicit assignment
* Make sure all streams are assigned to exactly one AdaptationSet

Oh, I also forgot to say; as far as I can see (on a sloppy read-through),
metadata is unused in this patch. If that's really true, skip it here and
only add it in the next patch where it is used. That makes this patch
slightly less confusing.
