some tweaks by me.
- retire local sample SQL schemas in files/; up-to-date ones from
upstream are installed in the doc dir.
- remove "from upstream" section of files/pdns.conf; instead use
this file as a header only, catted together with upstream's up-to-date
version. add uid setting in sample config.
pdnsd is a proxy dns server with permanent caching (the cache
contents are written to hard disk on exit) that is designed to cope
with unreachable or down dns servers (for example in dial-in
networking).
original port by dlg@ and robert@, banged into shape by me.
not hooked to the builds as this needs further testing/tweaking
