Guido van Rossum 25cb6e4ab4 Make Mapping covariant. (#512) ...

* Make Mapping covariant.

Fixes #510.

This requires a `# type: ignore` on `__getitem__` and `get` because
mypy complains about covariant parameters.

FWIW typing.py needs to be changed too.  (It was covariant in the
value but invariant in the key -- typeshed was invariant in both.)

* Delete outdated comment.

* Backpeddle a bit -- Mapping key type should not be covariant.
