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.
