Update manpage date to when the deprecation notice was removed.

rwho/ruptime/rwhod shouldn't be gated by RCMDS.

As peter@ points out in pr/220953:
"rwho, rwhod and ruptime are not part of the remote login suite (rsh, rlogin
etc).

They should *not* be in the rcmds package which is disabled by default. We
rely on rwho/rwhod/ruptime in the freebsd.org cluster."

This commit is a re-commit of r322029 and r322031 with a better commit log, as
pointed out by ngie@.

This also includes the necesary changes to OptionalObsoleteFiles.inc, as
requested by jhb@.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Remove stale references to utmp(5) and its corresponding filenames.

I removed utmp and its manpage, but not other manpages referring to it.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The Id line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
