• Update unbound to 1.5.7
• Bump PORTREVISIOn on dependent ports

Some Upgrade Notes:

This release fixes a validation failure for nodata with wildcards and
emptynonterminals. Fixes OpenSSL Library compability. Fixes correct
response for malformed EDNS queries. For crypto in libunbound there is
libnettle support.

Qname minimisation is implemented. Use qname-minimisation: yes to
enable it. This version sends the full query name when an error is
found for intermediate names. It should therefore not fail for names
on nonconformant servers. It combines well with
harden-below-nxdomain: yes because those nxdomains are probed by the
qname minimisation, and that will both stop privacy sensitive traffic
and reduce nonsense traffic to authority servers. So consider
enabling both. In this implementation IPv6 reverse lookups add
several labels per increment, because otherwise those lookups would be
very slow. [ Reference
