Refactoring, consisting of - remove unused method `isAuxiliaryLanguage` and `FileCountList` in order to reduce public API surfaces (go/java) - add GoDoc to public APIs - ci: java profile use latest go src It also now mimics https://docs.travis-ci.com/user/languages/go/#go-import-path for non-go build image, as code relies on internal imports. TEST PLAN: - make test
