[ravenwood] Make all classes and methods non-final

- Making them non-final allows mockito to use the traditional, subclass-based mock strategy, as opposed to "inline mocking", which is nice because inline mocking has some non-obvious gatchas.

- Other than that, this shouldn't affect any test behavior -- we still compile tests against the original jar, so tests still couldn't override final classes / methods.

(- It _could_ affect it if there were any tests that check class / method signatures, but I don't think we need to support such tests.)
