Redefine locale info in struct _reent for per-thread locales

Browse Source 
The _reent members _current_category and _current_locale are not
used at all.  _current_locale is set to "C" in various points of
the code but its value is just as unused as _current_category.

This patch redefines these members without changing the size of the
structure to allow for an implementation of per-thread locales per
POSIX-1.2008 (i.e. uselocale and usage of the per-thread locale in
subsequent function calls).
