pytype: don't warn us about ignored-on-py3 metaclasses
We can remove this when we're Python 3-only, but for now it's just too
awkward to deal with and it's harmless.

linelog: be more careful about types before looking for _target attribute
Without this, pytype (correctly) complains that fakejge might not have
a _cmprev attribute. We're operating on some constraints not
expressible in the type system, so we detect the invalid case and
raise a nicer exception now.
Sadly, we also need an `assert` to give PyType a clue that we know
what we're doing, but I can absolutely live with that.

linelog: suppress annoying pytype warning about an ignored metaclass
This isn't actively hurting us right now, and it's not trivial to set
up this metaclass correctly on both Python 2 and Python 3 without
dragging in all of `six`, but we still get lots of typechecking
goodness with this error suppressed.

hghave: add a check for pytype, Google's Python type checker
I'm not unbiased, but I strongly prefer pytype to mypy: it does more
inference, so we don't need as many annontations. In theory we can use
both, but since I'm doing some tinkering with pytype I figured I'd
just try setting it up.

encoding: define local identify functions with explicit type comments
This removes some obfuscation as far as pytype is concerned and
corrects many bogus type errors.
