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.

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.

Remove unnecessary free argument casts.
Don't abuse arcname's constness.

Cleanup pax(1) sources a little bit while I poked around in them:
- remove a superfluous doubled trailing semicolon.
- remove the extra void casts on calls to void-function free(3).

Remove clause 3 from the UCB licenses.

Fix a bazillion warnings. This makes almost the whole of src/bin/*

Correct typos, mostly s/ a / an / where appropriate. Some whitespace cleanup,
especially in troff files.

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.

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()

Rev 1.13 fixes PR bin/8958

There is a bug in /bin/pax -s option processing. The code assumes that all
pattern matches will occur at offset zero of the source string. The bug causes
the input source string pointer to be incremented by the offset of the end of
the match, instead of it's length. The fix is to only increment the pointer by
the length of the pattern match (eo-so).

Of course, the one example in the man page shows a situation where the match
occurs at offset 0.

You will find enclosed some changes to make gcc -Wall more happy in

I (Joerg) finished most of Philippe's cleanup. /bin/sh will still
