Initial work copied from https://github.com/NLnetLabs/ldns/pull/187, which was inadvertently closed when its author deleted his GitHub account.

Original PR description:

Hi, while working on CDS/CDNSKEY in Zonemaster I realized LDNS does not allow calling ldns_calc_keytag() on a CDNSKEY resource record (which is identical to a DNSKEY resource record).

Thanks @tgreenx (and ghost previously). This looks just fine. I'll merge and credit both you and ghost ;)
