Subject: Prepare for adding RMCP+ cipher suite 17

In many places, there are baked-in assumptions about algorithms that tie
the session initiation to cipher suite 3. This commit teases out those
assumptions and prepares for the next patch that actually adds in the
new authentication and integrity algorithms to support cipher suite 17.
