cmp(1): Provide some long options

These match GNU cmp(1) for compatibility where applicable.

Future work might implement the -i option from GNU cmp(1) to express skip
either in terms of both files or of the form "SKIP1:SKIP2" rather than
specifying them as additional arguments to cmp(1).

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.

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

Refine markup and add the EXIT STATUS section where appropriate.

-mdoc sweep.

Add a -h option to tell cmp not to follow symbolic links.

$Id$ -> $FreeBSD$

"EOF of file..." is written to stderr and not stdout.

PR: 6756

Correct usage string. Program name converted to bold in man page.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

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.
