[NL_CURRENT_INDIRECT]: ... with this one.
(_nl_current, _nl_C): Variables removed.

weak references to _nl_current_LC_FOO_used.
[NL_CURRENT_INDIRECT] (CATEGORY_USED): Define using that table.

* locale/localename.c (_nl_current_names): ... here, new file.
Make it global, with attribute_hidden.

(_NL_CURRENT_LOCALE): New macro, defined to fetch a tsd value.
(_NL_CURRENT_DATA): Define using that.
(_NL_CURRENT, _NL_CURRENT_WSTR, _NL_CURRENT_WORD): Define using that.
(_NL_CURRENT_DEFINE): Define to empty.
[! SHARED]: Decls of _nl_current_CATEGORY and _nl_current
conditionalized on this.
* locale/xlocale.c (NL_C_INTIIALIZER): New macro,
taking initializer of _nl_C_locobj.
[SHARED] (_nl_global_locale): New variable, using that initializer.
(_nl_C_locobj): Use new macro for initialzier.
