Fix various inheritances

I had a patch to stubtest that added checking of base classes. Unfortunately, it was too noisy to consider merging, although some fixes did come out of it. I complicated the patch today, and most of the following look actionable. Figured I'd jot the output down here, so it doesn't get forgotten about, since I'm not sure I want to merge this newly complicated patch (branch at https://github.com/hauntsaninja/mypy/tree/stubtestbaseclass). I'll chip away at these, but if someone reading this is looking to contribute to typeshed, this is a good place to start!
