Log Message:
Update PowerDNS to 3.4.1.

pkgsrc changes:
- SQLite 2.x support no longer exists
- SQLite 3.x support cannot be compiled outside the main package because
  of how symbols are distributed, so making it a compile time option
  for net/powerdns now.

Too many changes since 2.9.22.5 (over 2 years ago), see the full changelog:

  http://doc.powerdns.com/md/changelog/

Upgrade notes:

- PowerDNS 3.4 comes with a mandatory database schema upgrade coming from
  any previous 3.x release.
- PowerDNS 3.1 introduces native SQLite3 support for storing key material for
  DNSSEC in the bindbackend. With this change, support for bind+gsql-setups
  ('hybrid mode') has been dropped.
- PowerDNS 3.0 introduces full DNSSEC support which requires changes
  to database schemas. By default, old non-DNSSEC schema is assumed.

Please see the docs on upgrading for particular steps that need to be taken:
