Update to 1.9.0

• PR #246: Make ldns_calc_keytag() available for CDNSKEY RR Thanks tgreenx and pnax
• PR #247: Make ldns_key_rr2ds() available for CDNSKEY RR Thanks tgreenx
• PR #248: Make ldns_rr_compare_{ds,ds_dnskey}() available for CDS and CDNSKEY RRs. Thanks tgreenx
• PR #245: Make drill trace use IPv6 when used with -6 Thanks Paul Radford
• Fix #254: Unquoted "value" rdata for CAA records fail to validate. Follows the long string unquoted syntax from RFC8659, section 4.1.1.
• Fix #266: ldns-read-zone -u fails if a type is the only type in a window and the type modulo 256 is equal to zero.
• Fix #271: Intermittent build failure with multi-job builds (make -j).
• Add ldns-verify-zone -s option. It checks all signature results, instead of passing by when one RRSIG validates. That prints output for spurious RRSIGs, the failures for them.
• Fix RR types NSAP-PTR, GPOS and RESINFO to print unquoted strings.
• Fix memory leak when trying to read zones that have equal RRs. the ldns_dnssec_*_add_rr() functions now return LDNS_STATUS_EQUAL_RR when an already existing RR is tried to be added. This is a API change, hence this also bumps the version to 1.9.0
• PR #282: ensure returning pkt with LDNS_STATUS_OK. Thanks grobian.
• PR #286: Fix RR Type AMTRELAY type nogateway, to print relay '.', and memory leaks in parsing it.

• Fix #283: ldns-walk fails after update from 1.8.3 to 1.8.4 Thanks jschauma
• PR #200: Allow compiled tests to link to ldns statically via environment variable. Thanks FGasper and pemensik
• PR #220: Optionally exclude ZONEMD RRs in ldns-compare-zone Thanks gjherbiet
