First pass at adding locale support. This code only deals with the LC_CTYPE

class of locale data, but could be extended to handle other locale
classes, as well as message catalogues and other non-locale i18n
support.

I have left the old _ctype_ array in place, and moved the ctype.h
header to octype.h, so that existing shared binaries will still be
able to find and use it as they require.

See /usr/src/share/locale for information on how to create new locale
data files (eventually this procedure will be improved).  I'd like to
have a family of locale files for various countries, languages, and
character sets, so please contribute some.

This code was originally written by Paul Borman and contributed to
4.4; I did the integration, and have somewhat tested it.  crt0.c
probably ought to call setlocale() if it doesn't already, but I'd like
for people to create some locale files and try things manually first
before I make every program do this.
