MFC all features as of r248336:

The user visable feature is from r246083:

Add -l option to cat(1). This option causes cat(1) to use fcntl(2) to
set an exclusive advisory lock on stdout. This will be used to guarantee
orderly writing to METALOG.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

One more nit.

Fix markup.

Add the new standard EXIT STATUS section where appropriate.
Sort standard sections in the (documented) preferred order.

Eliminate macro calls inside literal displays.

/*- or .\"- or #- to begin license clauses.

Remove clause 3 from the UCB licenses.

OK'ed by: imp, core

Reduce redundancy in the description of the -u option.

Document incorrect handling of multibyte characters when -t and -v options
are used.

mdoc(7) police: fixed markup.

Give /bin/cat the ability to connect to and read unix-domain sockets

MFC after: 1 week

mdoc(7) police: utilize the new .Ex macro.

Xref zcat(1).

Prepare for mdoc(7)NG.

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

Use Dq Li (double-quoted literal) instead of Ic (internal command) to
mark up a sample invocation, since it is not a command internal to the
described utility.

Do not use Ar (argument) to mark up something which is not an argument
to the utility or one of its internal commands.

Sync us up to OpenBSD's cat.1 v1.18 and cat.c v1.9.

This gets rid of a bogus cast of NULL in setbuf().
Lets us know the buffer malloc failed.

Reworks the manpage a bit to make it more mdoc(7) compliant, adds
examples.

Remove unnecessary empty line.
Remove trailing whitespace.

$Id$ -> $FreeBSD$

Various spelling/formatting changes.

Submitted by: Philippe Charnier <charnier@xp11.frmug.org>

Restore Lite2 sccsids by removing `const'. Improve documentation a little.
Suggested by: Bruce

Correct use of .Nm, .An and other cosmetics. Add rcsid. Remove unused #inc.

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.

Merge Lite2 mods and -Wall cleaning.
