* eval.c (ev_const_defined): adopt to ev_const_get() using
rb_const_defined_fallback().
* variable.c (rb_const_get_fallback): new function to implement
constant search.
* variable.c (rb_const_defined_fallback): new function to
implement constant definition check.
* variable.c (rb_const_get_0): adopt to new behavior. constants
are looked up in the order of: current class, super classes (but
Object), lexically external classes/modules, and Object.
* variable.c (rb_const_defined_0): ditto.

the file. [ruby-dev:24191]
* ext/digest/digest.c: use rb_obj_class() instead of CLASS_OF
which might return singleton class. [ruby-dev:24202]
