Rework conversation data types and make safe wrappers. This removes the old `Conversation` type and reworks the FFI types used for PAM conversations. This creates safe `TestResponse` and `BinaryResponse` structures in `conv`, providing a safe way to pass response messages to PAM Conversations. The internals of these types are allocated on the C heap, as required by PAM. We also remove the Conversation struct, which was specific to the real PAM implementation so that we can introduce a better abstraction. Also splits a new `PamApplicationHandle` trait from `PamHandle`, for the parts of a PAM handle that are specific to the application side of a PAM transaction.
