performed, so that with nonzero target-fetch-policy it fetches forwarder addresses and uses them from cache. Also updated that delegation point cache fill routines use CDflag for AAAA message lookups, so that its negative lookup stops a recursion since the cache uses the bit for disambiguation for dns64 but the recursion uses CDflag for the AAAA target lookups, so the check correctly stops a useless recursion by its cache lookup.
