Better class name management.

The change removes several internal instance variables used by
class name management. The variables `__classid__` and `__classpath__`
are no longer available. `__outer__` is used only for unnamed outer
classes/modules (and will be removed after they are named).

[Important note]
Along with this change we removed several public functions.

 - mrb_class_outer_module()
 - mrb_class_sym()

We believe no one have used those functions, but if you do, please
ask us for the workaround.
