So what did they specify for reallocarray in POSIX now? What does it
return if either element size or number of elements is 0? Being able to
return NULL in that case is quite desirable and the only reason various
malloc implementations do not is crappy code like in xlib that assume a
NULL pointer returned is always an error.
