lorder: Undeprecate.

While lorder is not required by our current toolchain (or any toolchain
we've used in the past decade or two), it still occasionally shows up
in build systems of third party software, including The Open Group's
UNIX conformance test suite, and the maintenance cost is negligible.

lorder: Clean up and improve robustness.

* Properly parse (no) command-line options.

* Ensure that errors go to stderr and result in a non-zero exit.

* Drop the special-case code for a single argument, as it will produce
the wrong outcome if the file does not exist or is corrupted.

* Don't print anything until after we've collected all the data.

* Always create all temporary files before setting the trap. This
ensures that the trap can safely fire at any moment, regardless of any
previous definition of `T`.

* Use a temporary file rather than a pipe between `nm` and `sed` to
ensure proper termination if `nm` fails due to a missing or invalid
input.

* The check for self-referential entries was conditional on testing our
argument list against a regex looking for archives. This was a
needless and unreliable optimization; make the check unconditional.

* Document that lorder will not work properly if any of its inputs have
spaces in their name.

usr.bin: Remove ancient SCCS tags.

minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

lorder: add deprecation notice

lorder has not been used by the base system since 0e1e341b486c and
hasn't really been necessary for a very long time.

lorder: add note that it is no longer required

Use of lorder(1) is not required by contemporary linkers.

The GNU coreutils manual[1] has a good description of the use of lorder
and tsort:

This whole procedure has been obsolete since about 1980, because
Unix archives now contain a symbol table (traditionally built by
ranlib, now generally built by ar itself), and the Unix linker uses
the symbol table to effectively make multiple passes over an archive
file.

See 0e1e341b486c for some more details.

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.

Introduce a new make variable: NMFLAGS.

As the name indicates, these are flags to pass to nm(1). The newer
binutils have a plugin mechanism so, to build something with LLVM's
LTO, we need to pass flags to nm(1). This commit also extends
lorder(1) to pass NMFLAGS to nm(1).

Remove the advertising clause from UCB copyrighted files in usr.bin. This
is in accordance with the information provided at

Also add $FreeBSD$ to a few files to keep svn happy.

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.

Document the NM environment variable.

Markup fixes.

ru@ recently changed lorder to support library archives. Document
this new feature prominently. Bump date while I'm here.

Deal with double whitespace.

$Id$ -> $FreeBSD$

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.

pascal and vmstat.sparc. All changed files on the vendor branch should
