For testability, and to allow the exchange of debug information when forwarding the LSP, it will be necessary to access debug information stored in cache objects. This is cumbersome to do if our constructors return source interfaces rather than concrete types. This CL changes cache.New and (*Cache).NewSession to return concrete types. This required removing NewSession from source.Cache. I would argue that this makes sense from a philosophical perspective: everything in the source package operates in a context where the Session and Cache already exist.
