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.

ncurses: chase dependency changes in the source tree

Differential Revision: https://reviews.freebsd.org/D32098

Convert to usr.bin/ to LIBADD
Reduce overlinking

Replace all uses of libncurses and libtermcap with their wide character
variants. This allows usable file system images (i.e. those with both a
shell and an editor) to be created with only one copy of the curses library.

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.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

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

Cleanup:
- Change signedness of nxtfld() to make msgs(1) WARNS=6 clean
- Add several static's

Remove leaf node WARNS?=2 (that mainly I added). This should
help the GCC3 transition and CURRENT in general.

Fix WARNS=2 warnings on alpha and i386 and clamp it down

$Id$ -> $FreeBSD$

Finish importing Lite2's src/usr.bin, except for ex, diff, grep, mail,
pascal and vmstat.sparc. All changed files on the vendor branch should
already have been imported.

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.

Use tcflush(), eliminate libcompat.

Change all references to LIBTERM and -ltermlib to LIBTERMCAP and -ltermcap
