[PATCH] locale: Make _nl_C_locobj_ptr usable outside of libc

I need something like this to fix incorrect locale dependence in
libresolv (bug 19687).
I tested this with the fixes, including one for nscd, which uses
__libc_C_locobj@GLIBC_PRIVATE. libresolv uses _nl_C_locobj@GLIBC_PRIVATE.
I'm not entirely sure if we should use the function approach everywhere
instead. But as far as I can tell, this patch does not lead to the
allocation of space for a _nl_C_locobj copy in libresolv (which we would
not want because it is wasteful).
An alternative would add of functions such as those in <ctype.h> and
strcasecmp/strncasecmp which are always tied to the C locale. This
would be more efficient because access to the locale object is easier,
or the variants can even be optimized inline (such as isblank).
Thanks,
Florian
