96015e4766 (From FreeBSD) 
Get things right for tty names of length UT_LINESIZE. (FreeBSD PR 3638)
If the utmp login time is greater than the tty atime, use it to calculate
the idle time instead of the atime.
Fix -n with 16-chars hostnames (FreeBSD PR 11286).
Domain names are case insensitive.

2af1e46eab __CONCAT does token pasting, not string concatnation. if something like: 
__CONCAT("foo","bar");
actually works to concantate strings, it's because the preprocessor expands
it into "foo""bar" as separate strings, and then ANSI string concatenation
is performed on that.  It's more straightforward to just use ANSI string
concatenation directly, and newer GCCs complain (rightly) about misuse
of token pasting.

f8031c2d6d add code to recognize special ftpd utmp entries and match corresponding 
process accordingly, so that w parses entries made by "ftpd -U" correctly

the new code is conditionalized upon define SUPPORT_FTPD_UTMP, turned
on by default in w(1)'s Makefile

This addresses bin/11095 by Daniel Hagerty.

2120a34cd6 - Don't core dump when we have stale utmp entries; warn the user instead. 
- Make this work again in single user when invoked as uptime and utmp is
  not present.

0afebfffdf Redo previous slightly differently - restore the behaviour of two 
characters for the tty name and the first 'T' of 'TTY' hanging over
the blank column at the end of the username field.

ce5e5c761e - Set the minimum width for login name to 4, the width of "USER". 
- Fix the number of colmuns left for proc. args.  Previously, an effect of
  NUL was canceled implicitly, but now we must handle it explicitly.
- Fix the width for tty name.

b00d9cf6cc Use p_login from struct proc instead of ut_name from struct utmp so 
that a truncated name isn't used if the login name is over 8 characters
long.  Size USER field to suit.

80efe80bc9 - change setgid kmem programs (that lend themselves to this) so setegid(getgid()) 
and the top, and then set the effective gid back to kmem around the call to
  kvm_openfiles().  this reduces the time group kmem is available.
- for those above that also allow this, setgid(getgid()) after the call to
  kvm_openfiles() to fully revoke priviledges.

cc3bb2da02 Fix from John Brezak for the following bug: 
If there is a non-tty entry in utmp, w(1) will exit with an error.
However there are legitimate non-tty entries, for instance an xlogin via
xdm can be identified with the xlogin program. In this case there is an
entry with the display name as the ut_tty.
