usr.sbin: 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.

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.

Remove the advertising clause from UCB copyrighted files in usr.sbin. This

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.

mdoc(7) police: markup fixes.

Changes which rewrite 'lpc topq', and which add 'lpc bottomq'. These
reflect much valuable feedback from wollman. More details on the new
'lpc topq' are in the log message for revision 1.2 of lpc/movejobs.c.

The previous implementation of 'lpc topq' is available as 'lpc xtopq',
in case there are any problems noticed in the new implementation. If
there are no problems with this version, a later update will remove the
'lpc xtopq' command.

The .Nm utility

Add a nearly complete rewrite of the lpc command 'down'. The only user-
visible change should be that more than one queue can now be specified,
if one uses the '-msg' parameter to separate the list of queues from the
status message to set.

The previous implementation of 'down' remains available as the command
'xdown', available for instant fallback if there seems to be anything
wrong with the new one. If no one reports a problem after a few weeks,
then a later update will remove 'xdown'.

Make the description of the 'down' command a little more readable.

Add a new command to 'lpc' called 'setstatus', which would be used to
change the status message of a print queue. This includes some minor
changes to the upstat() routine, so that error messages are not printed
while seteuid(priv-user).

Add description of `mc' (max copies), add short-form to long-form mapping

lpr-related man pages.

mdoc(7) police: removed hard sentence breaks, use new .Brq macro.

Make 'lpc clean' somewhat safer. Add an 'lpc tclean' command, which allows
one to see what files would be removed *if* an 'lpc clean' is done. 'tclean'
will remove no files, and is therefore not a privileged command. Also, both
'lpc clean' and 'lpc tclean' will now look for 'core' files in spool directories
(but not remove them). They also print out an extra line of info when a
datafile to be removed is a symlink (from 'lpr -s'), saying what file it is
a symlink to.

The 'lpc clean' commands also now print out a summary line saying how many
queues were checked, how many files were removed (or "would be" removed, for
tclean), and how much disk space is involved. For the benefit of those who
have many print queues, 'lpc clean all' will only print out the names of print
queues where some "interesting" files were found, instead of printing out a
header-line for every queue in your printcap file.

mdoc(7) police: use the new features of the Nm macro.

Remove single-space hard sentence breaks. These degrade the quality

$Id$ -> $FreeBSD$

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.

Pull a bunch of fixes from the 4.4BSD-Lite2 branch. It's really
surprising how many trivial errors there have been... :-)

Some more cleanup is needed, but i'd like to separate the Lite2 changes
from other work, that's why this goes into a different commit.

People with serial printers should see whether i have broken the stty-
style printcap options (i hope not).

Vendor-branch import of the 4.4BSD-Lite2 code for lpr. There are
several bugfixes in it that are worth considering.

Don't be alarmed about the import conflicts...

Correct some man page xrefs, and some other minor changes to bring some
man pages up to mdoc guidelines and fix some minor formatting glitches.
Also fixed a number of man pages to not abuse the .Xr macro to
display functions and path names and a lot of other junk.
