  xmalloca, etc.: fix some xalloc-oversized issues
  
  * lib/malloca.h (nmalloca):
  * lib/xmalloca.h (xnmalloca): Convert S to ptrdiff_t to avoid
  arithmetic overflow if N and S are both narrower than ptrdiff_t.
  * lib/xalloc-oversized.h (xalloc_oversized):
  Don’t say that args must be ptrdiff_t or size_t or wider.
  The macro returns the correct answer even when that is not
  the case, and it’s the caller’s responsibility to avoid
  howlers like (xalloc_oversized (n, s) ? NULL : malloc (n * s))
  when N and S are both narrower than ptrdiff_t and size_t.
  Add a comment to that effect.
  * lib/xmalloca.h: Include xalloc-oversized.h, since this file uses
  xalloc_oversized.  Add comments about side effects and avoid
  unnecessary parens.
  * modules/xmalloca (Depends-on): Add xalloc-oversized.
