bin: Automated cleanup of cdefs and other formatting

Apply the following automated changes to try to eliminate
no-longer-needed sys/cdefs.h includes as well as now-empty
blank lines in a row.

Remove /^#if.*\n#endif.*\n#include\s+<sys/cdefs.h>.*\n/
Remove /\n+#include\s+<sys/cdefs.h>.*\n+#if.*\n#endif.*\n+/
Remove /\n+#if.*\n#endif.*\n+/
Remove /^#if.*\n#endif.*\n/
Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/types.h>/
Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/param.h>/
Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/capsicum.h>/

bin: 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.

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.

Eliminate unneeded includes.

Fix warnings found by -Wmising-variable-declarations.

This self-written compiler warning, which is hopefully going to be
committed into LLVM sources soon, warns about potentially missing
`static' keywords, similar to -Wmissing-prototypes.

- bin/pax: Move external declaration of chdname and s_mask into extern.h.
- bin/setfacl: Move setfacl.c-specific stuff out of setfacl.h.
- sbin/mount_fusefs: Remove char *progname; use getprogname().
- others: add `static' where possible.

Fix a bunch of typos and a couple of whitespace nits.

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.

Don't decend into directories when -d is set and the directory itself doesn't
match.

Ooops, forgot to remove the registers here.

o __P has been reoved
o Old-style K&R declarations have been converted to new C89 style
o register has been removed
o prototype for main() has been removed (gcc3 makes it an error)
o int main(int argc, char *argv[]) is the preferred main definition.
o Attempt to not break style(9) conformance for declarations more than
they already are.

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.

Whitespace cleanup pass; reduce diffs with OpenBSD. No functional changes.

Reduce diffs with OpenBSD:
#if __STDC__ -> #ifdef __STDC__
pax_warn() -> paxwarn()
sys_warn() -> syswarn()
(foo *)NULL -> NULL
bcopy -> memmove()/memcpy()
bzero -> memset()
Typo fixes
sprintf() -> snprintf()
rindex() -> strrchr()
index() -> strchr()
sys_errlist[] -> strerror()

Remove simultaneous include of <sys/param.h> and <sys/types.h>.
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.

-Wall cleaning.

Remove unneded ctype.h everywhere
Add setlocale LC_TIME

Remove trailing whitespace.
