wollman 4542c1cf5d Fix all areas of the system (or at least all those in LINT) to avoid storing
socket addresses in mbufs.  (Socket buffers are the one exception.)  A number
of kernel APIs needed to get fixed in order to make this happen.  Also,
fix three protocol families which kept PCBs in mbufs to not malloc them
instead.  Delete some old compatibility cruft while we're at it, and add
some new routines in the in_cksum family.
