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.

Rename O_DIRECTORY to O_TMP_DIRECTORY to avoid shadowing the fcntl.h

Everyone's favorite: finally bump vi's escapetime.

Closes bin/2510: vi escape keys over slow... (and i think yet another one)

Submitted by: kargl@troutmask.apl.washington.edu (Steven G. Kargl)

Bump default escapetime from 1 (ie: 100ms) to 3 (ie: 300ms). Hopefully
this will make it less likely to misinterpret arrow keys as seperate
keys when running over anything slower than a console.

This has been talked about for a while, I hope it's long enough but not
too long to be annoying.

This commit was generated by cvs2svn to compensate for changes in r19304,
which included commits to RCS files with non-trunk default branches.

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.
