Create new delegation point from a dns message.
<p>
Note that this method does not actually test to see if the message is an actual referral. It really is just checking to see if it can construct a delegation point, so the message could be of some other type (some ANSWER messages, some CNAME messages, generally.) Note that the resulting DelegationPoint will contain targets for all "relevant" glue (i.e., address records whose ownernames match the target of one of the NS records), so if policy dictates that some glue should be discarded beyond that, discard it before calling this method. Note that this method will find "glue" in either the ADDITIONAL section or the ANSWER section.<p>
