Convert the structural metadata to GstMiniObjects to make a lot of
code easier and to make everything better extensible.
Add a "registry" for metadata handlers to improve extensibility even
more and to remove metadata type specifics from mxfdemux.
Clean up a lot of parts and add some more NULL checks.
