usr.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.

Fix handling of corrupt compress(1)ed data. [11:04]

Add missing length checks on unix socket addresses. [11:05]

Security: FreeBSD-SA-11:04.compress
Security: CVE-2011-2895 [11:04]
Security: FreeBSD-SA-11:05.unix

Remove the advertising clause from UCB copyrighted files in usr.bin. This
is in accordance with the information provided at
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

Also add $FreeBSD$ to a few files to keep svn happy.

Discussed with: imp, rwatson

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

Correct some typos in comments, no functional changes.

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.

Remove unneeded header includes from usr.bin/ except contributed code.

Tested with: make universe

- Import the HEAD csup code which is the basis for the cvsmode work.

Unbreak r1.11 by delhij. Blind change from unsigned to signed char
pointer causes problems with sign extension and leads to compress(1)
dumping core on any non-trivial incoming data.

Consistently use signed char so gcc4 won't complain

ANSIify function definitions to avoid a warning.

remove __P

Style improvements recommended by Bruce as a follow up to some
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

Use __FBSDID().
Use a better choice than size_t for vertain variables.
Fix some comment alignment.

WARNS=2 fix and 'register' removal.

Tweaks to allow compiling -Wall (mostly adding "const" to char rcsid[]).

a header file for zopen.3

Pointed out by: Philippe Charnier <charnier@lirmm.fr>

Correct the usage of the maxmaxcode so that compress -b 12 works again.
Thanks to Dave Rivers for reporting that problem.

Add David River's patch fix to use the passed in number of bits (-b <n>)
properly.
