Remove copyright strings ifdef'd out

We've ifdef'd out the copyright strings for some time now. Go ahead and
remove the ifdefs. Plus whatever other detritis was left over from other
recent removals. These copyright strings are present in the comments and
are largely from CSRG's attempt at adding their copyright to every
binary file (which modern interpretations of the license doesn't
require).

minor fixup to keep things compiling. All the common forms in the tree

pax(1): Honour the restrict in sigaction().

Use a setup_sig() helper and make it fail when either of sigaction fails.

While there, do not leak fds for "." + minor cleanup.

General further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

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.

Implement pax -O option to permit limiting a PAX archive to a single volume.

not prompt for a new volume.

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.

Sync up with OpenBSD. Too many changes to note, but the major features
are:
* Implement cpio compatibility mode when pax is invoked as cpio
* Extend tar compatibility mode to cover many of the GNU tar single-letter
options (bzip2 mode, aka -y/-j is not present in OpenBSD). When
invoked as tar, pax is now full-featured enough for use by the ports
collection to extract distfiles and create packages.
* Many bug fixes to the operation of pax and the tar compatibility modes
* Code fixes for things like correct string buffer termination.

I tried to preserve existing FreeBSD fixes to this utility; please let me
know if I have inadvertently spammed something.

Add -z flag to pax to allow gzipping of archive output. Add -z and -Z (gzip
and compress) to pax when used in tar mode (invoked as 'tar') for
compatibility with GNU tar.

bzip2 functionality for further GNU tar compatibility will be added at a
later date.

Note in the manpage that -z is non-standard.

Developers took this wrong. LC_TIME specifies the locale
name, not the ``format'' argument of strftime().

Oops:
pax -w -f /tmp/foo /dev/null
LC_TIME=de_DE.ISO_8859-1 pax -v -f /tmp/foo

Reorder includes to be alphabetical some places since I already was in

Dont have an internal function named "warn" it clashes with libc..
Needed for ELF.

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.
