This adds negative trust anchor support and allows reading trust anchor data from disk, from files /etc/systemd/dnssec-trust-anchors.d/*.positive and /etc/systemd/dnssec-trust-anchros.d/*.negative, as well as the matching counterparts in /usr/lib and /run. The positive trust anchor files are more or less compatible to normal DNS zone files containing DNSKEY and DS RRs. The negative trust anchor files contain only new-line separated hostnames for which to require no signing. By default no trust anchor files are installed, in which case the compiled-in root domain DS RR is used, as before. As soon as at least one positive root anchor for the root is defined via trust anchor files this buil-in DS RR is not added though.
