Roland McGrath 963102971d * locale/localeinfo.h (struct locale_data): Add private.ctype.
* wcsmbs/wcsmbsload.h (__wcsmbs_gconv_fcts, __wcsmbs_last_locale,
	__wcsmbs_to_wc, update_conversion_ptrs): Removed.
	(__wcsmbs_gconv_fcts_c, _nl_C_LC_CTYPE): New externs.
	(__wcsmbs_load_conv): Remove const from argument.
	(_nl_cleanup_ctype): New proto.
	(get_gconv_fcts): New function.
	* wcsmbs/wcsmbsload.c (__wcsmbs_last_locale): Removed.
	(__wcsmbs_to_wc): Rename back to...
	(to_wc): ... this.
	(__wcsmbs_gconv_fcts): Rename to...
	(__wcsmbs_gconv_fcts_c): ... this.  Make const.  Use to_wc.
	(lock): Removed.
	(__libc_setlocale_lock): New extern.
	(__wcsmbs_load_conv): Remove const from argument.
	Initialize new_category->private.ctype instead of a global
	variable.
	(__wcsmbs_clone_conv): Use get_gconv_fcts instead of
	update_function_ptrs.  No locking is necessary.
	(_nl_cleanup_ctype): New function.
	* wcsmbs/btowc.c (__btowc): Use get_gconv_fcts instead of
	update_function_ptrs and a global __wcsmbs_gconv_fcts variable.
	* wcsmbs/mbrtowc.c (__mbrtowc): Likewise.
	* wcsmbs/mbsnrtowcs.c (__mbsnrtowcs): Likewise.
