[2.1.1p4] utmp patch for SunOS 4.1.x

Follow-on to Charles Levert's <charles at comm.polymtl.ca> work on
utmp_write_direct.
Fixed:
-- At logout, the utmp entry is cleared. Tested on SunOS 4.1.4.
The code I added to loginrec.c is restricted to SUNOS4 pending
QA testing on other platforms.
This patch incorporates the work done by Charles Levert on
7/25/2000 00:43:22. (Do any of us sleep at night?)
Remaining:
-- Test on NeXT and other operating systems that need utmp_write_direct
(those without entutent, getutent, getutid, getutline, ...) If
successful, the SUNOS4 restriction could be removed and the FIXME
can be eliminated. If not, similar code will need to be added
to support those operating systems.
-- In the unlikely case that other operating systems have prereqs.
for ttyent.h, those .h files will need to be added to configure.in,
includes.h, and config.h.in.
Install: (prereq: GNU autoconf and Larry Wall's patch)
o save attached context diffs to "patchfile"
-- patch < patchfile (apply patch to 2.1.1p4 release)
-- autoconf (generate configure, config.h, etc.)
o follow ssh install docs. In a nutshell,
-- configure
-- gmake
-- gmake install
