  The idea is that in *normal* circumstances, the server just Does the
Right Thing.  If it receives a discover, and the policy returns "ok",
then the response should be an offer.

  In some cases, the server needs to send an explicit NAK, in order to
force the client to re-broadcast a discover.

  I've committed a change that lets the policy set the message type.
