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

correct description of what will happen when a AuthorizedKeysCommand is specified but AuthorizedKeysCommandUser is not (sshd will refuse to start)

remember which public keys have been used for authentication and refuse to accept previously-used keys. This allows AuthenticationMethods=publickey,publickey to require that users authenticate using two _different_ pubkeys. ok markus@

/dev/random has created the same effect as /dev/arandom (and /dev/urandom) for quite some time. Mop up the last few, by using /dev/random where we actually want it, or not even mentioning arandom where it is irrelevant.

Inspired by and similar to Adam Langley's proposal for TLS: http://tools.ietf.org/html/draft-agl-tls-chacha20poly1305-03 but differs in layout used for the MAC calculation and the use of a second ChaCha20 instance to separately encrypt packet lengths.
