Implement low-level conversation primitives.
This change does two primary things:
1. Introduces new Conversation traits, to be implemented both
by the library and by PAM client applications.
2. Builds the memory-management infrastructure for passing messages
through the conversation.
...and it adds tests for both of the above, including ASAN tests.
