Remove most of old resolve

resolve has a few type definitions in it that are used, so I left
those and deleted everything else. Also, I switched rustdoc to use
resolve3 instead of the old resolve.

In a future commit I'll remove the type definitions entirely, as they're
just duplicates of types defined in resolve3.
