Initializing a pointer to struct __locale_t to point to a string "C"
is not such a bright idea in the long run...

Add global const __C_locale for reference purposes.

Don't use global variables. This allows to call loadlocale from
the yet to be created newlocale().
Rename _thr_locale_t to __locale_t (these locales are not restricted
to threads so the name is misleading).
Along these lines, fix _set_ctype to take a __locale_t as parameter.

Introduce first cut of struct _thr_locale_t used for the locale_t definition.
Introduce global instance called __global_locale used by default.
Introduce internal inline functions __get_global_locale, __get_locale_r,
__get_current_locale.
Remove usage of global variables in favor of accessor functions pointing to
__global_locale for now. Include all local headers in locale subdir from
setlocale.h to get single include for internal locale access.
Introduce __CTYPE_PTR macro to replace direct access to __ctype_ptr__
and use throughout in isxxx functions.

_GNU_SOURCE generally enables all features, but in this case the POSIX
requirement to #include <wctype.h> for these is preferred.

This typedef, along with that of FILE in wchar.h, were XSI prior to
inclusion in POSIX.1-2008.

Many wchar.h functions were never properly guarded; these changes should
make the header fully compliant.

MAXFLOAT, M_PI, and friends date back to at least XPG4v2, so this guard
was incorrect even prior to the feature test macros overhaul.

The _reent members _current_category and _current_locale are not
used at all. _current_locale is set to "C" in various points of
the code but its value is just as unused as _current_category.
This patch redefines these members without changing the size of the
structure to allow for an implementation of per-thread locales per
POSIX-1.2008 (i.e. uselocale and usage of the per-thread locale in
subsequent function calls).

gettimeofday is currently guarded with __MISC_VISIBLE || __XSI_VISIBLE.
However, gettimeofday should be always visible, as in GLibc.

The proper location for these functions has always been <stdio.h>, however
XPG4 and SUSv2 did mandate a duplicate declaration in <unistd.h>. cuserid
was dropped in SUSv3 (it was marked legacy since XPG4) and the ctermid
declaration in <unistd.h> was made optional and obsolete in SUSv4.

The following testcase:
$ cat > test.c <<EOF
#include <sys/select.h>
#include <sys/time.h>
EOF
$ gcc -c test.c
emits the following error:
/usr/include/sys/reent.h:276:3: error: expected specifier-qualifier-list befor
e ‘_fpos64_t’
_fpos64_t _EXFNPTR(_seek64, (struct _reent *, _PTR, _fpos64_t, int));
^
The reason is that the load order from sys/select.h includes sys/_types.h
before sys/config.h has been included from anywhere else. sys/_types.h
defines _fpos64_t only if __LARGE64_FILES is defined, but it never is in
this scenario. So sys/_types.h has to make sure to get the configuration
info by itself.

Various FreeBSD source and header files need a typedef __size_t via
<sys/_types.h>. Unfortunately the GCC provided <stddef.h> uses
#if (defined (__FreeBSD__) && (__FreeBSD__ >= 5)) \
|| defined(__DragonFly__) \
|| defined(__FreeBSD_kernel__)
/* __size_t is a typedef on FreeBSD 5, must not trash it. */
#elif defined (__VMS__)
/* __size_t is also a typedef on VMS. */
#else
#define __size_t
#endif
and therefore defines __size_t on Newlib targets which would trash a
__size_t typedef. Include <stddef.h> before <sys/_types.h> in
<sys/types.h> and undefine __size_t in <sys/_types.h> as a workaround.
