Peter Wemm f0957ccae4 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.

* The MARK and LMARK structures define positions in the file. There are
* two structures because the mark subroutines are the only places where
* anything cares about something other than line and column.
*
* Because of the different interfaces used by the db(3) package, curses,
* and users, the line number is 1 based and the column number is 0 based.
* Additionally, it is known that the out-of-band line number is less than
* any legal line number. The line number is of type recno_t, as that's
* the underlying type of the database. The column number is of type size_t,
* guaranteeing that we can malloc a line.
