DNSKEY, NXT vs NSEC and SIG vs RRSIG.
1658. [func] Update dnssec-keygen to default to KEY for HMAC-MD5
and DH. Tighten which options apply to KEY and
DNSKEY records.
1581. [func] Disable DNSSEC support by default. To enable
DNSSEC specify "enable-dnssec yes;" in named.conf.
1565. [bug] CD flag should be copied to outgoing queries unless
the query is under a secure entry point in which case
CD should be set.
1558. [func] New DNSSEC 'disable-algorithms'. Support entry into
child zones for which we don't have a supported
algorithm. Such child zones are treated as unsigned.
1557. [func] Implement missing DNSSEC tests for
* NOQNAME proof with wildcard answers.
* NOWILDARD proof with NXDOMAIN.
Cache and return NOQNAME with wildcard answers.
1541. [func] NSEC now uses new bitmap format.
1519. [bug] dnssec-signzone:nsec_setbit() computed the wrong
length of the new bitmap.
1516. [func] Roll the DNSSEC types to RRSIG, NSEC and DNSKEY.
