Implement xlocale APIs from Darwin, mainly for use by libc++. This adds a
load of _l suffixed versions of various standard library functions that use
the global locale, making them take an explicit locale parameter. Also
adds support for per-thread locales. This work was funded by the FreeBSD
Foundation.

Please test any code you have that uses the C standard locale functions!

Add support for the 6 new C99 struct lconv members dealing with formatting
international monetary values: int_p_cs_precedes, int_n_cs_precedes,
int_p_sep_by_space, int_n_sep_by_space, int_p_sign_posn, int_n_sign_posn.
This should not break existing binaries or LC_MONETARY data files.

Make FreeBSD locale support complete: add support for rest locale categories
LC_MONETARY, LC_NUMERIC and LC_MESSAGES. Remove stub functions since they
don't need anymore.
