vasnwprintf: Fix test failures on FreeBSD, NetBSD, AIX, mingw.
* m4/printf.m4 (gl_SWPRINTF_WORKS): New macro.
* m4/vasnprintf.m4 (gl_PREREQ_VASNWPRINTF): Invoke it and define
HAVE_WORKING_SWPRINTF accordingly.
* lib/vasnprintf.c: Together with HAVE_SWPRINTF, test also
HAVE_WORKING_SWPRINTF.
(VASNPRINTF): If WIDE_CHAR_VERSION && !DCHAR_IS_TCHAR, don't pass a
wchar_t[] to snprintf. Add a workaround against mingw's snwprintf
function.
* doc/posix-functions/swprintf.texi: Document the null wide character
bug.
