(mxf_up_create_caps), (mxf_up_init): * gst/mxf/mxfup.h: 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.
