    iface_tcp: agressively close the TCP port
    
    - revamp the iface read path so that the interface specific code
      returns struct msg_digest and can close the event's IFP
    
    - for TCP, when EOF, delete the event handler and delref(IFP) stopping
      further EOFs
    
    - for TCP, when reading the very first message, transfer the event's
      IFP to the message digest (i.e., addref()/delref() leaving the
      message digest with the only reference)
    
      If the packet is rejected then the message digest, including that
      IFP, will be deleted.
    
      OTOH, if the packet is accepted then the new state is given the
      reference to IFP.
