make mbuf tags suck a bit less, performance wise.
the most common operation is checking for a particular tag to be there.
in the majority of the cases it is not.
introduce a "tagsset" in the mbuf packet header which has a bit for
each mbuf tag type that is in the chain set, checking for its existance
is now as easy and cheap as (tagsset & type) != 0. theo ok
