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.

Add a couple of examples.

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

Spelling fixes.

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.

Allow creating hard links to symlinks using ln(1).

This implements the POSIX.1-2008 -L and -P flags.

The default remains to create hard links to the target of symlinks.

Clean up a bit of confusing language and improve .Nd.

- Import the HEAD csup code which is the basis for the cvsmode work.

Add a -w warning flag to ln(1). When the -w option is enabled,
ln(1) checks to see if the source of a symlink, i.e. the file it
should point to actually exists. The default is the old ln
behavior, that does not check, to avoid surprising people who may
be using ln(1) in scripts or other non-interactive places.

Claim conformance to 1003.2-1992 instead of 1003.1-2001 due to doubts

ln(1)'s symbolic link handling conforms to IEEE Std. 1003.1-2001, note
this in the Standards section.

Correctly mark up the final command line arguments with the Ar macro for
the last two synopsis forms.

Fix cut'n'paste niggles in previous commit.

Add link(1) and unlink(1) as special cases of ln(1) and rm(1)
respectively, in accordance with SUSv2.

This differs from the approach taken in NetBSD, but provides
less obscure error messages in at least the EISDIR case and
does not take up additional disk space for new binaries.

Correct use of .Nm. Add rcsid.

Revert $FreeBSD$ to $Id$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
