Subject: Move Validator._resolver to _ref_resolver.

Makes way for our newer resolver to live in the shorter name.

(This should have no effect on the public API, where we have
Validator.resolver returning this attribute after emitting a deprecation
warning.)

Also bumps the minimum attrs version we depend on, as we need the alias
functionality.
