    Fix constant rekeying.
    
    Another piece of fallout from this morning's patch series, which I
    didn't notice until I left a session running for more than an hour:
    once do_ssh2_transport is told to begin a rekey, it has no way of
    knowing _not_ to immediately do another one, and another, and so on.
    
    Added a value RK_NONE to the rekey class enumeration, and set
    rekey_class to that immediately after a key exchange completes. Then a
    new one won't start until some code actually sets rekey_class to a
    nonzero value again.
