Defines the constant "empty" DUID.
In general, empty DUID is not allowed. The only case where it is really valid is to designate declined IPv6 Leases. We have a broad assumption that the Lease->duid_ must always be set. However, declined lease doesn't have any DUID associated with it. Hence we need a way to indicate that fact.
