This version incorporates many fixes in particular a fix for vi -w
Another approach was proposed to merge those fixes (see review), I find
it easier to track changes if we keep importing snapshot on regular
basis

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
Current logic of using user's locale encoding that is UTF-8 doesn't make
much sense if we already failed the looks_utf8() check and skipped
encoding set using "fileencoding" as being UTF-8 as well; fallback to
ISO8859-1 in that case.

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.

This prevents any background sub-command executed from inheriting
the descriptor & lock (and making vi think that someone else is
editing the file when it re-edits).
