* object.c (rb_mod_to_s): Module#{to_s,inspect}, when invoked on

  a refinement, returns a string in the format #<refinement:C@M>,
  where C is a refined class and M is a module at which the refinemet
  is defined.

* eval.c (rb_mod_refine): store information on a refinement for the
  above change.

* test/ruby/test_refinement.rb: related test.
