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).

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.

Fix formatting. ruptime output on FreeBSD cluster machines annoyed me
by usually being double-spaced due to auto-wrap at column 80.

r212771 increased width of the hostname field from 12 to 25. This was
supposed to allow for 80-column output with all 3 load averages taking
5 characters each, but it actually gave width exactly 80 and thus worse
than useless auto-wrap in that case. 3 wide load average fields are
unusual, but later expansion of another field gave the auto-wrap with
just 2 wide load average fields.

Change to dynamic field widths for all fields except the uptime. This
also fixes the formatting of high (above 9999) user counts and not
very high (above 9.99) load averages. The formatting for numbers now
breaks at 99999.99, but scientific notation should be used starting
well below that.

The field width for the uptime remains hard-coded to work consistently
for uptimes less than 10000 days, but this gives too much space for
small uptimes. Punctuation between fields could be improved in many
ways, for example by removing it.

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.

Add missing static keywords to ruptime(1)

Make some internal fixes to ruptime(1):

- Prevent possible unaligned access to struct whoent.
- Increase uptime column by one, to properly print hosts with an uptime
greater than 1000 days.
- Reduce code complexity by storing struct whod inside struct hs.
- Set WARNS to 6.

Remove the advertising clause from UCB copyrighted files in usr.bin. This

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Increase the hostname display width. Many machines are named
with >12 characters. This still allows for 80 column output
with load averages of 99.99, 99.99, 99.99.

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.

Revert most part of 200420 as requested, as more review and polish is
needed.

Sync program's usage() with manpage's SYNOPSIS.

Add functionality to only list hosts specified on the command line. If none
are specified the old behaviour is old. The submitted applied a much cleaner
diff to ruptime.c, however it did not cover cases like listing failures. It
would probably be a good idea to move the printing from the ruptime function,
and have that function just be used to build the list, as that would unbreak
sorting, but this diff is intended to be clear, relative to the original
code. As the sort order is the order specified on the command line, for now,
such is documented in the manual page accordingly.

$Id$ -> $FreeBSD$

Small formatting change to interval() to align columns so that:

toronto up 5+18:58, 0 users, load 0.00, 0.00, 0.00
zeus up 109+13:53, 0 users, load 0.55, 0.28, 0.15

looks like:

toronto up 5+18:58, 0 users, load 0.00, 0.00, 0.00
zeus up 109+13:53, 0 users, load 0.55, 0.28, 0.15

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.
