rb_iterator_p() is the function to check whether the calling function
is called with block.  rb_f_iterator_p() is the function to implement
the method `iterator?'.  Since `iterator?' itself is the method,
rb_f_iterator_p() checks 1 level above.  You are not supposed to call
rb_f_iterator_p() from your C function.  That's why is's static.
