When -n is not specified, resolve IPv6 as well as IPv4 addresses found
in the host field of utmp. Use realhostname_sa() to resolve addresses
(the old code was wrong).
Rename ``x'' to ``x_suffix'' to avoid confusion.
Hard code the host column width to 16 (against the imminent increase
of UT_HOSTSIZE in utmp.h).

This makes entries for people that have logged in but done nothing
else show up correctly.

only scalar values and structures that are already part of the
kernel/user interface, specifically rusage and rtprio. It no
longer contains proc, session, pcred, ucred, procsig, vmspace,
pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If
any of these changed in size, ps, w, fstat, gcore, systat, and

of unassigned space for future values to be added, yet is nearly
100 bytes smaller per entry than the structure that it replaced.

one character shorter than the previous in a stairstep fashion when long
idle times were involved.
A couple of nits:
- spelling/typo fix.
- some of the easier style(9) fixes where it was bothering me.
- Handle 100+ days idle time (ha!). Probably the right thing to do is
to do a snprintf into a buffer and strlen the result rather than doing
hackery on magic numbers.
XXX the wide (and mostly unused) username and tty columns annoy me since
it it could be used for more useful information for the command. We should
actually count the largest username and tty and adjust like 'ls -l' does.

with this size why isn't the w command reporting it?

This gives us more room to breath with tty names, especially with drivers
that support large numbers of ports.. eg: specialix and digiboard.
This does not actually change the current tty names, it just allows room
for reporting more characters if the drivers use them.
a gethostbyname() on it. That can take a long time... (especially
if the reason the IP address is in there in the first place is because
login/rlogind/telnetd couldn't find it either....)
This patch reduces the gethostbyaddr lookup time to 2 seconds, the idea being
that if the local nameserver knows the answer, it'll answer within that time,
otherwise we dont care... :-)
This change doesn't do anything about whether or not w should do this in the
first place, but at least it will make the current behavior less painful.
