Summary: Bozo getstate w/ slots overrides base

Initial Comment:
The bozo __getstate__ set automatically on classes
defining __slots__ overrides any __getstate__ defined
in a base class.  This makes writing a mixin to
implement this method impossible.

This issue is that although the base class B defines a
__getstate__, the class C2 overrides it b/c it contains 
__slots__.  Basically, I'm suggesting that base classes
should be checked for getstate instead of only looking at
the class that defines slots before adding the bozo'd version.

Unfortunately, I don't have a 2.3* version to play with at
the moment.  Please let me know if this clarifies things.

What do you expect to be printed?  I'm not sure what you
want changed.  Have you tested with 2.3b1?  Does this meet
your needs?
