cleanup routine, we don't look at bogus data to determine wheter or not
to free the fields of the hostdata struct. This cures the "klogin segfaults
when no kerberos servers are availible" problem.
(Including all changes for FreeBSD - importing the original eBones distribution
would be too complex at this stage, since I don't have access to Piero's
CVS.)
(If you want to include eBones in your system, don't forget to include
MAKE_EBONES in /etc/make.conf.)
(This stuff is now also suppable from braae.ru.ac.za.)
Bones originally from MIT SIPB.
Original port to FreeBSD 1.x by Piero Serini.
Moved to FreeBSD 2.0 by Doug Rabson and Geoff Rehmet.
Nice bug fixes from Doug Rabson.
