* iconv/gconv_int.h (__GCONV_NULCONV): New internal only error code.
* iconv/gconv_cache.c (__gconv_lookup_cache): Return __GCONV_NULCONV
if from and to charsets are the same.
* iconv/gconv_db.c (__gconv_find_transform): Likewise.
* intl/dcigettext.c (_nl_find_msg): Return NULL even if __gconv_open
returns __GCONV_NOCONV, but not for __GCONV_NULCONV.

* wcsmbs/wchar.h: Only define wint_t if __need_wint_t.
Don't define wint_t when __need_mbstate_t unless it
is necessary.
(__mbstate_t): Use __WINT_TYPE__ rather than wint_t
in the typedef if possible.
* wctype/wctype.h (wint_t): Define by including
wchar.h with __need_wint_t instead of including stddef.h
with __need_wint_t and as fallback definining it ourselves.
* iconv/gconv.h (__need_wint_t): Define before including
wchar.h.
* sysdeps/gnu/_G_config.h: Don't include gconv.h if not _LIBC
or _GLIBCPP_USE_WCHAR_T.
(__need_wchar_t): Don't define
if not _LIBC or _GLIBCPP_USE_WCHAR_T.
(__need_wint_t): Don't define before including stddef.h,
define before including wchar.h only if _LIBC or
_GLIBCPP_USE_WCHAR_T.
(_G_iconv_t): Don't define if not _LIBC or _GLIBCPP_USE_WCHAR_T.
* sysdeps/mach/hurd/_G_config.h: Likewise.
* sysdeps/generic/_G_config.h: Likewise.
* libio/libio.h (__wunderflow, __wuflow, __woverflow): Only
prototype if _LIBC or _GLIBCPP_USE_WCHAR_T.
(_IO_getwc_unlocked, _IO_putwc_unlocked): Only define
if _LIBC or _GLIBCPP_USE_WCHAR_T.
