Subject: [PATCH] Cleanup: apply `include-what-you-use` guideline for
 `mbstate_t`

I saw that some files use the `mbstate_t` type but there are not including
a header for it. The `mbstate_t` type is defined by the following header:
  <wchar.h>

So, to follow the best practice of including what is used in a file, I
added `#include <wchar.h>` in files using `mbstate_t`.
