SECURITY UPDATE: allocation of resources without limits or throttling
debian/patches/CVE-2024-1737-1: introduced new configurable limits
that prevent the loading (into zones or into cache) of DNS resource
records (RRs) that exceed them
debian/patches/CVE-2024-1737-2: add environment variable
DNSRDATASETMAXRECORDS, DNSRBTDBMAXRTYPES to override hardcoded
limits DDNSRDATASETMAXRECORDS and DDNSRBTDBMAXRTYPES. Add
masterformat tests for testing RRsets.
