Subject: * numeric.c (int_to_f, fix_to_f): rename fix_to_f to int_to_f, and
 add   treatment for subclasses which don't have definitions of to_f method.

* numeric.c (Integer#to_f, Fixnum#to_f): move to_f method from Fixnum
  to Integer.

* ext/-test-/integer/my_integer.rb: define helper class for testing
  to_f method for a subclass of Integer.

* ext/-test-/integer/extconf.rb: ditto.

* ext/-test-/integer/init.c: ditto.

* test/-ext-/integer/test_my_integer.rb: examine to_f method for a
  subclass of Integer.
