merges r21093 from trunk into ruby_1_9_1.

* eval.c (rb_frame_callee, rb_frame_caller): rb_frame_callee()
  should return method id on current frame.
  add rb_frame_caller() to get method id on parent frame.
  Bug #884 [ruby-dev:37446]
* eval.c (rb_f_method_name): use rb_frame_caller()
  instead of rb_frame_callee().
