Address SF #451547.  The approach is a bit draconian: any object that is pickled as a global must now exist by the name under which it is pickled, otherwise the pickling fails.  Previously, such things would fail on unpickling, or unpickle as the wrong global object.  I'm hoping that this won't break existing code that is playing tricks with this.

I need a volunteer to do this for cPickle too.
