The client has an internal state machine which tells it what message it
should expect next from the server based on its current state. Only
certain messages are legal at any one time. The variable mt holds the
message type of the message it is expecting to receive. The variable p
points into the message buffer for the message that it has actually
received. If the message sent from the server doesn't match the one the
client was expecting then you get this error.
