Generates a metadata tag event from the given taglist.
The scope of the taglist specifies if the taglist applies to the
complete medium or only to this specific stream. As the tag event
is a sticky event, elements should merge tags received from
upstream with a given scope with their own tags with the same
scope and create a new tag event from it.
