lib: Remove ancient SCCS tags.

Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

Remove $FreeBSD$: one-line nroff pattern

Remove /^\.\\"\s*\$FreeBSD\$$\n/

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.

Revert most of r210764, now that mdocml does the right
thing with empty quotation macros.

Requested by: Alex Kozlov

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

mdoc: make sure to pass at least one argument to quotation macros

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.

Remove the advertising clause. UCB did this some time ago, but these
files were never updated to reflect that.

MFC After: 2 days

mdoc(7) police: Use the new .In macro for #include statements.

Introduce .Lb macro to libkvm manpages.
Use .Pa macro for "enlighting" path

$Id$ -> $FreeBSD$

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.

The previous commit was bogus. <stdlib.h> was never a prerequisite
for <kvm.h> or kvm_getloadavg(), and <sys/types.h> was only a
prerequisite for <kvm.h> when <kvm.h> was broken.

Add required #include references to manual page

Fixed #include and/or prototype bugs in synopsis.

Sort cross references.

Fix the short description of kvm_getloadavg(3) to reflect
what the function really does.

Also fix a small mdoc problem I noticed while in there.
