* ctype/ctype.h (__ctype_b, __ctype_toupper, __ctype_tolower):

	Variable declarations removed.
	(__ctype_b_loc, __ctype_toupper_loc, __ctype_tolower_loc): Declare
	these functions to replace them.
	(__isctype, tolower, toupper, _tolower, _toupper): Use those accessor
	functions plus an indirection rather than the old global variables.
	* include/ctype.h (__isctype, tolower, _tolower, toupper, _toupper):
	Macros removed.
	(__ctype_b_loc, __ctype_toupper_loc, __ctype_tolower_loc): New extern

	* ctype/ctype-info.c: Revert last reversion back the other way.
	Define tsd vars CTYPE_B, CTYPE_TOLOWER, CTYPE_TOUPPER.
	Define real function versions of include/ctype.h inlines here.
	* ctype/Versions (libc: GLIBC_2.3): Add __ctype_b_loc,
	__ctype_tolower_loc, __ctype_toupper_loc.
	* locale/lc-ctype.c: Revert last reversion back the other way.
	(_nl_postload_ctype): If current thread uses the global locale,
	update its tsd vars.
	* locale/uselocale.c (__uselocale): Update tsd vars from new locale.
	* hurd/hurd/threadvar.h (enum __hurd_threadvar_index): Add CTYPE_B,
	CTYPE_TOLOWER, CTYPE_TOUPPER.

	* sysdeps/generic/bits/libc-tsd.h (__libc_tsd_address): New macro.
