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 inline functions. * 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. * sysdeps/mach/hurd/bits/libc-tsd.h (__libc_tsd_address): Renamed from __libc_tsd_threadvar_location. (__libc_tsd_set, __libc_tsd_get): Update uses.
