irmd: Complete bidirectional flow re-keying
Extend re-key delivery beyond the locally-initiated watermark path:
Handle peer-initiated re-key requests, allowing one request and one
response per flow at a time. The client side wins if both ends try to
re-key at the same time. Caches the peer certificate to support
cert-less authenticated/signed re-keys.
After a rekey, the initiator promotes first (timer) and starts sending
under the new key. The responder observes the new key (peer_synced)
and then the responder promotes. The responder will self-decide to use
the new keys if it exhausted the older set in the case where it never
sees the peer (unidirectional flow).
