Select a random unused source port in the RFC 5881 range (retrying on EADDRINUSE) instead of unwrapping a pure-random bind. Propagate bind errors out of session start-up, store the local IP on the session instead of unwrapping local_addr(), and log (rather than panic on) receive errors in the rx loop.
Replace the hard-coded addresses with clap arguments: --bind <IP> and one or more --peer <IP>. Peers must match the address family of the bind address. Also updates Cargo.lock.
Can now establish and hold a session with BIRD, successfully detect Down
state, and call scripts on state change via an event dispatch engine.
Can't maintain a session with VyOS. I think it is calculating the timers
incorrectly, but don't trust my own implementation of course...
