* Make most of blib2to3 directly typed and mypyc-compatible
This used a combination of retype and pytype's merge-pyi to do the
initial merges of the stubs, which then required manual tweaking to
make actually typecheck and work with mypyc.

* Make black able to compile and run with mypyc
The changes made fall into a couple categories:
* Fixing actual type mistakes that slip through the cracks
* Working around a couple mypy bugs (the most annoying of which being
that we need to add type annotations in a number of places where
variables are initialized to None)
