As part of the conversion to a `struct peer_connection` it will be desirable to have 2 pointers one for when we open a connection and one for when we receive a connection. Start this actual conversion over to this in `struct peer`. If this sounds confusing take a look at the bgp state machine for connections and how it resolves the processing of this router opening -vs- this router receiving an open. At some point in time the state machine decides that we are keeping one of the two connections. Future commits will allow us to untangle the peer/doppelganger duality with this abstraction.
