Check resolution API signatures for invalidation

[davidmorgan]

When a file is resolved, record the (transitive) API signature.

On the next build, when choosing whether to build: if the only thing that has changed is a transitive import of something that was resolved, check the API signature and only rebuild if the API signature changed.

Work in progress: not for merge due to fork of analyzer class into analysis_driver_for_package_build. The change to that file is small, only the new method libraryApiSignature.
