Corinna Vinschen 88208d3735 POSIX-1.2008 per-thread locales, groundwork part 2
Move all locale category structure definitions into setlocale.h and remove
other headers in locale subdir.  Create inline accessor functions for
current category struct pointers and use throughout.  Use pointers to
"C" locale category structs by default in __global_locale.
