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.

The nvi maintainer expects this patch to be included in the upcoming
nvi-1.81.6 unless a better fix presents itself.
The MFC reminder below should be taken as a cue to MFC rev 1.1.1.2
of vs_relative.c as well.
