This is the pre-release, for reporting build issues and their ilk.

New IPv6 address for one of the root servers in the default root server
configuration.  And a number of bug fixes, for CD flags to forwarders,
for 0x20 compatibility, for qname-minimisation with DNSSEC.

Features
    generic edns option parse and store code.
    Updated L root IPv6 address.
    User defined pluggable event API for libunbound
    ip_freebind: yesno option in unbound.conf sets IP_FREEBIND for
binding to an IP address while the interface or address is down.
    OpenSSL 1.1.0 portability, --disable-dsa configure option.
    disable-dnssec-lame-check config option from Charles Walker.

Bug Fixes

trailing dot.

CD bit on the first attempt to a forwarder, but CD bit thereafter on
repeated attempts to get DNSSEC.
