New locale support (in development). Supports LC_CTYPE, LC_NUMERIC,

  LC_TIME, LC_MONETARY, and LC_MESSAGES for the SUSv3 items.  Also,
  nl_langinfo() when real locale support is enabled.
New implementation of ctype.h.
New implementation of wctype.h.
New implementation of most of the string functions (smaller).
New implementation of the wcs/wmem functions.  These are untested, but
  they're also just preprocessor-modified versions ot the corresponding
  str/mem functions.
Tweaked qsort and new bsearch.

Stuff still pending:
stdlib.h and wchar.h  mb<->wc functions.  I actually have working
   versions of the stdlib ones, but the reentrant versions from
   wchar.h require some reworking.
Basic replacement and translit support for wc->mb conversions.
   (groundwork laid).
Simple-minded collate support such as was provided by the previous
   locale implementation.  (mostly done -- 8-bit codesets only)
Shared mmaping of the locale data and strerror message text.
