upstream commit
Host key rotation support. Add a hostkeys@openssh.com protocol extension (global request) for a server to inform a client of all its available host key after authentication has completed. The client may record the keys in known_hosts, allowing it to upgrade to better host key algorithms and a server to gracefully rotate its keys. The client side of this is controlled by a UpdateHostkeys config option (default on). ok markus@
