Add a frozenness check to Enumerator#initialize.
* enumerator.c (enumerator_init): Add a frozenness check to
prevent a frozen Enumerator object from being reinitialized with
a different enumerable object. This is the least we should do,
and more fixes will follow. [Fixes GH-368] Patch by Kenichi
Kamiya.
