o Initialize the PRED1 input queue when we

receive the ResetAck, NOT when we send the
   ResetReq (as per the rfc).
o  SILENTLY ignore CCPs that arrive *before*
   the network phase (as per the rfc).
o  Check that we've actually negotiated PRED1
   before sending PRED1 output.
   This bug has been around for a *VERY* long
   time !  We shouldn't need to explicitly disable
   PRED1 now :-)
