Pass mbrtowc() and wcrtomb() NULL instead of a pointer to a freshly zeroed
mbstate_t object that they ignore. The zeroing is fairly expensive, and it
will never be necessary in these functions; when we support state-dependent
encodings, we will pass in a pointer to the file's mbstate_t object, and
only zero it at the time the file gets opened.
