ldns_pkt_edns()  returns true if this packet needs and EDNS rr to be sent.  At the moment the only reason
              is an expected packet size larger than 512 bytes, but for instance dnssec would be a  good  reason
              too.

              packet: the packet to check
              Returns true if packet needs edns rr

              packet: the packet
              Returns the rcode

       ldns_pkt_edns_version() return the packet's edns version
              packet: the packet
              Returns the version

       ldns_pkt_edns_z() return the packet's edns z value
              packet: the packet
              Returns the z value

       ldns_pkt_edns_data() return the packet's EDNS data
              packet: the packet
