nvi: import version 2.2.1

Update nvi to 2.2.0

Main changes:
* Vim-style expandtab option
* Provides Turkish translation
* Backspace now deletes \ rather than being escaped
* T during motion commands is now VI-compatible
* Encoding related fixes, such as UTF-8 detection
* Fixed a number of memory management issues

MFC after: 3 weeks

Update nvi to 2.1.3 which fixes the data corruption when locale conversion
failed

Merge nvi-2.1.1 -> 2.1.2

Update nvi-1.79 to 2.1.1-4334a8297f

This is the gsoc-2011 project to clean up and backport multibyte support
from other nvi forks in a form we can use.

USE_WIDECHAR is on unless building for the rescue crunchgen. This should
allow editing in the native locale encoding.

USE_ICONV depends on make.conf having 'WITH_ICONV=YES' for now. This
adds the ability to do things like edit a KOI8-R file while having $LANG
set to (say) en_US.UTF-8. iconv is used to transcode the characters for
display.

Other points:
* It uses gencat and catopen/etc instead of homegrown msg catalog stuff.
* A lot of stuff has been trimmed out, eg: the perl and tcl bindings which
we could never use in base anyway.
* It uses ncursesw when in widechar mode. This could be interesting.

Post-cvs2svn flatten pass.

Import of nvi-1.79, minus a few bits that we dont need (eg: postscript
files, curses, db, regex etc that we already have). The other glue will
follow shortly.

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.
