pdns: add package

Maintainer: me

Compile tested: armv7l, OpenWRT SDK
Run tested: armv7l Linksys WRT1900ACS, OpenWrt SNAPSHOT, r9987-655fff1571 -
confirmed PowerDNS server links correctly against libraries. I'm unable to test
all the backend modules as I don't have suitable backing stores set up for each.

Description:
PowerDNS is a versatile nameserver which supports a large number of different
backends ranging from simple zonefiles to relational databases and load
balancing/failover algorithms. PowerDNS tries to emphasize speed and security.

This commit includes the authoritative nameserver, backends and additional tools
