* vm.c (eval_get_cvar_base): destination for class variable access

  is now strictly innermost surrounding class or module.  warned
  if accessed from toplevel.

* variable.c (rb_cvar_get): new class variable look-up scheme:
  1) look up in the class.  2) if the class is singleton attached
  to a class (i.e. metaclass) then start look up in the attached
  class and its ancestors. 3) otherwise, look-up in ancestors of
  the class.

* eval.c (cvar_cbase): destination for class variable access is
  the class/module that holds the method, or cbase outside of
  methods.
