Hi

Ticket #9079 brought this about. This should prevent accidentally
adding local tags that are not registered in the primer. It also allows
us to omit tags that we know won't be used, in a manner that is more
elegant than the old code.

The actual meat of this patch is mxf_mark_tag_unused(),
mxf_write_primer_pack(), mxf_write_local_tag() and
ff_mxf_lookup_local_tag()

fate-mxf passes of course, since this doesn't actually change the
output of the muxer.
