Declare ge25519_base as extern, to prevent it from
becoming a common. Gets us rid of ``lignment 4 of symbol
`crypto_sign_ed25519_ref_ge25519_base' in mod_ge25519.o is smaller than 16 in
mod_ed25519.o'' warnings at link time.
Some packet error messages show the address of the peer,
but might be generated after the socket to the peer has suffered a TCP reset.
In these cases, getpeername() won't work so cache the address earlier.

in order to give the user a chance to notice if unintentionally running
without it

Let sshd load public host keys even when private keys are
missing. Allows sshd to advertise additional keys for future key rotation.
Also log fingerprint of hostkeys loaded; ok markus@
Add a ssh_config HostbasedKeyType option to control which
host public key types are tried during hostbased authentication.
This may be used to prevent too many keys being sent to the server,
and blowing past its MaxAuthTries limit.

correctly match ECDSA subtype (== curve) for
offered/recevied host keys. Fixes connection-killing host key mismatches when
a server offers multiple ECDSA keys with different curve type (an extremely
unlikely configuration).
ok markus, "looks mechanical" deraadt@
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).

Provide a warning about chroot misuses (which sadly, seem
to have become quite popular because shiny). sshd cannot detect/manage/do
anything about these cases, best we can do is warn in the right spot in the
man page. ok markus
