28 November 2007: Wouter
- Changeup plan for 0.8 - no complication needed, a simple solution
has been chosen for authoritative features.
- you can use single quotes in the config file, so it is possible
to specify TXT records in local data.
- fixup small memory problem in implicit transparent zone creation.
- test for implicit zone creation and multiple RR RRsets local data.
27 November 2007: Wouter
- per suggestion in rfc2308, replaced default max-ttl value with 1 day.
- set size of msgparse lookup table to 32, from 1024, so that its size

- Can be used for complicated setups. So, run auth server on a
different port or pc, and stub it on the resolver. Resolver is
not auth for zones, but resolution works. This enforces the split
of recursive and auth servers.

* option to use real entropy for randomness (mix it in once in a while).

redirect. If not matched exactly, the local-zone type determines
further processing. If local-data is configured that is not a subdomain of
a local-zone, a transparent local-zone is configured.
For record types such as TXT, use single quotes, as in
local-data: 'example. TXT "text"'.
