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).

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

Mark usage function as __dead2 in programs where it does not return

In most cases, usage does not return, so mark them as __dead2. For the
cases where they do return, they have not been marked __dead2.

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.

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.

Do not emit a spurious warning when "directory" argument
to "rmdir -p" is absolute, with one or more leading slash.

Fixed "rmdir -p" that got broken by rev. 1.15.
(This also fixes "rmdir -v /nonexistent".)

Added -v to usage().

Remove clause 3 from the UCB licenses.

Add a -v (verbose) option.

Quiet warnings about copyright[].

Consistently use FBSDID

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.

Correct use of .Nm. Add rcsid.

Don't strip trailing slashes (for the initial rmdir). It breaks
following of the symlink for `rmdir symlink/' and is unnecessary
for ordinary directories (POSIX doesn't require rmdir(1) to do
anything for trailing slashes; it requires rmdir(2) to let them
"refer to a directory", and following the symlink for symlink/ is
what BSD does). This also fixes bugs in the slash-stripping code
(for paths consisting entirely of slashes, the pointer into the
string was decremented to "before" the beginning of the string,
and the path was at best stripped to "".

The behaviour is unchanged except for the final directory for
`rmdir -p ...'. There is no alternative to stripping intermediate
slashes since they must be specified. The sloppy slash-stripping
code is adequate for intermediate directories, since the all-slashes
case fails early.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

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.
