Rename xlocale.h to bits/types/__locale_t.h.
xlocale.h is already a single-type micro-header, defining struct __locale_struct and the typedefs __locale_t and locale_t. This patch brings it into the bits/types/ scheme: there are now bits/types/__locale_t.h which defines only __locale_struct and __locale_t, and bits/types/locale_t.h which defines locale_t as well as the other two. None of *our* headers need __locale_t.h, but it appears to me that libstdc++ could make use of it. There are a lot of external uses of xlocale.h, but all the uses I checked had an autoconf test or equivalent for its existence. It has never been available from other C libraries, and it has always contained a comment reading "This file is not standardized, don't rely on it, it can go away without warning" so I think dropping it is pretty safe. I also took the opportunity to clean up comments in various public header files that still talk about the *_l interfaces as though they were completely nonstandard. There are a few of them, notably the strtoX_l and wcstoX_l families, that haven't been standardized, but the bulk are in POSIX.1-2008. * locale/xlocale.h: Rename to... * locale/bits/types/__locale_t.h: ...here. Adjust commentary. Only define struct __locale_struct and __locale_t, not locale_t. * locale/bits/types/locale_t.h: New file; define locale_t here. * locale/Makefile (headers): Update to match. * include/xlocale.h: Delete wrapper. * include/bits/types/__locale_t.h: New wrapper. * include/bits/types/locale_t.h: New wrapper. * ctype/ctype.h, include/printf.h, include/time.h * locale/langinfo.h, locale/locale.h, stdlib/monetary.h * stdlib/stdlib.h, string/string.h, string/strings.h, time/time.h * wcsmbs/wchar.h, wctype/wctype.h: Use bits/types/locale_t.h. Correct outdated comments regarding the standardization status of the functions that take locale_t arguments. * stdlib/strtod_l.c, stdlib/strtof_l.c, stdlib/strtol_l.c * stdlib/strtold_l.c, stdlib/strtoul_l.c, stdlib/strtoull_l.c * sysdeps/ieee754/ldbl-128ibm/strtold_l.c * sysdeps/ieee754/ldbl-64-128/strtold_l.c * wcsmbs/wcstod.c, wcsmbs/wcstod_l.c, wcsmbs/wcstof.c * wcsmbs/wcstof_l.c, wcsmbs/wcstold.c, wcsmbs/wcstold_l.c: Don't include xlocale.h.
