* libc/stdio/vfwprintf.c (wcvt): Add a new parameter len of type
int. *length is set to the value of (rev - digits) regardless
of whether _MB_CAPABLE is defined or not. Replace BUF with len
in calling _mbsnrtowcs_r and also in the loop where _MB_CAPABLE
is not defined.
(_VFWPRINTF_R): Call wcvt with an extra argument. Call wcvt
again with allocated new buffer if buf is not large enough for
the conversion.
* testsuite/newlib.stdio/stdio.exp: New.
* testsuite/newlib.stdio/swprintf.c: Likewise.
