wireprotoserver: make response handling attributes private

wireprotoserver: make response handling attributes private

The send* methods are specific to sshserver and aren't part of the
common protocol interface. So rename them accordingly.

The handlers dict is also specific to sshserver and is related to
these methods. So give it the same treatment.
