/* The various kinds of startup messages are for the various kinds of
user authentication systems. In the beginning, there was only
STARTUP_MSG and all connections were unauthenticated. Now, there are
several choices of authentication method (the client picks one, but
the server needn't necessarily accept it). So now, the STARTUP_MSG
message means to start either an unauthenticated or a host-based
authenticated connection, depending on what the server prefers. This
is possible because the protocol between server and client is the same
in both cases (basically, no negotiation is required at all).
