were added with the login class stuff. This is needed since libutil.so.2.1
is what is used in RELENG_2_2 and well into the release cycle. We only
bump once per release cycle as needed.
also add the missing declaration of forkpty() to libutil.h.
Btw., the calling interface for login(3) is crude. Some better
abstraction is needed, perhaps similar to logwtmp(3).
2.2 candidate, but i'll wait for the spelling police first. :)
Install (optional) libutil.h with prototypes for the functions and
document this in the man page.
minor cleanups to the various routines, include the prototype file, declare
return codes etc.
replace the dozen other various hacks in the code that do all sorts
of crude things including spamming the envrionment strings with the new
argv string.
This version is mainly inspired by the sendmail version, with a couple of
ideas taken from the NetBSD implementation as well.
