sigh - people change their SOA serials a lot these days. PowerDNS tries to store all different SOA records of a domain.
After a few hours you might have as much as 2000 .COM SOA records in your cache, and we try to output them all..

Also, scrounge the cache a bit more for stale entries.

ok, I lied - rfc 4255 has chosen In All Its Wisdom to implement SSHFP as base-16 instead of base-64, like all the other crypto records. This is probably to make cutting & pasting from .ssh/known_hosts easier. Added support for hexadecimal records.
