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.

Remove $FreeBSD$: one-line .c pattern

Remove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/

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.

- Move 'showthreads' check out of fmt.c.
- Update shadow copy of fmt_argv() prototype in w.c and fix calls for
additional parameter.

Include the thread name along with the command name when displaying the
command name of a thread from a multi-threaded process that doesn't have
an available argument list (such as kernel processes) and threads display
is enabled via -H.

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.

Get rid of a cast to '(void) ' on the return of a call to strcpy.

Oops. Undo that last 'const' change. It expects similar changes to some
other files that I am not ready to commit yet...

Add 'const' to a few places.

When displaying the "COMMAND" field for system-processes and/or kernel
threads, put the command name in square brackets instead of parenthesis.
This matches NetBSD, and also seems to be what linux does. The sentence
which is added to the man page is taken straight from NetBSD.

Cast arg_max to size_t when comparing it (times 4, plus 1) against SIZE_MAX. I
was worried about truncation of arg_max by this cast, but if it gets truncated,
we know it'll obviously be greater than SIZE_MAX anyway.

Returning NULL here if malloc(3) fails is silly, at this point in the codepath
we have't malloc(3)'d nearly as much as we probably will, so errx(3) away,
instead of waiting for something to fail yet again later on.

Remove an XXX comment that seems to be a tiny bit no longer pertinent. This
function seems to do the right thing, and is not a "stub", and whoever "marc"
is, he's had plenty of time to do "the real one", so don't wait around for
him any longer.

Use of zero here meant many things, NULL, '\0' (NUL), and 0. Sort it out.

Check for possible overflow from sysconf _SC_ARG_MAX and error out in a
correct manner. Revert my incorrect change to use err(3) for malloc(3)
failing. Use a size_t variable to store the size of the argument buffer
we allocate, and remove silly casts as the result of having this around.
Modify the math in some of the paranoid checks for buffer overflow to
account for the fact we now are dealing with the actual size of the
buffer. Remove the static qualifier for arg_max, and the bogus setting
of it to -1.

Include <limits.h> for the definitions we use to check for possible
overflows.

Don't cast incorrectly to malloc(3), and don't use errx(3) if malloc(3)
returns NULL, as malloc(3) sets errno. Use err(3).

WARNS=4 fixes (incomplete, so set NO_WERROR), and lots of extra
cleanup courtesy of automatic checking (lint).

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.

Prevent overflowing the buffer that stores the command arguments.

Fix an error to prevent some core dumps from ps.
You can get ps easily to core dump, if you are running a "make depend"
on a kernel in one window and a "ps -auxww" in another. The ww will
try to give you the full argument list of the command that can
now be 64Kb large, but ps expected only 4Kb large arg arrays and
doesn't check for overflows.

Got rid of extra space between args and (command).
