Detailed Description

The handshake phase machine, RFC 4253 sec 4.2 through sec 10.

One connection walks the transport layer's own progression, then hands over to RFC 4252:

IDENT (sec 4.2) -> KEXINIT (sec 7.1) -> DH_INIT (sec 8) -> NEWKEYS (sec 7.3)
  -> SERVICE (sec 10) -> AUTH (RFC 4252) -> OPEN (RFC 4254)

and sec 9 sends an established connection back to KEXINIT for a re-exchange. The advance functions are named for the RFC event that causes them and are the only writers of the phase; the admits functions are the questions the dispatch asks before acting on a message.
