[CFT] ncurses wide character support

[Rong-en Fan]

Finally, I have ncurses wide character support. Patch is at

http://people.freebsd.org/~rafan/ncurses/ncursesw-5.6-fbsd7-20070128.diff

Before you can apply it, you need to

mkdir -p \
	/usr/src/lib/ncurses/formw \
	/usr/src/lib/ncurses/menuw \
	/usr/src/lib/ncurses/ncursesw \
	/usr/src/lib/ncurses/panelw

Please note this patch accidentally removes libmytinfo (it is going to be
removed soon). I have tested on my i386 current with mutt. It works just
fine.

I use a hack in src/Makefile.inc1 to make amd64 world + lib32 work. Details
can be found in

http://lists.freebsd.org/pipermail/freebsd-hackers/2007-January/019408.html

Please test and feedbacks are welcome. :)
