Don't regenerate session handshake keypair for every handshake so a global state can be used; remove the concept of temporary peers
These changes will fix the possibility of a TCP-SYN-Flood-like DoS attack, at the cost of another
protocol change: as we can't count request IDs when we don't know have temporary peers, request IDs
are removed completely.
