* 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...
