The `__eq__` method from our base class was not getting called, because we defined `tp_hash` as `NotImplemented`. Per [the docs on `tp_hash`](https://docs.python.org/3/c-api/typeobj.html#c.PyTypeObject.tp_hash), `tp_hash` and `tp_richcompare` are inherited together, so defining `tp_hash` was inhibiting the inheritance of `tp_richcompare`.

The previous change did not have the desired effect, because the generated code uses the class named "Message" instead of "CMessage."
There was no real need to use the class "CMessage" instead of "Message." The new name is simpler and will make the previous change work.
