Update to 20050415. Changes:

* Add "djbdns" rc.d script to control all enabled djbdns services,
    modeled after the "qmail" rc.d script from mail/qmail-run.
* Set rc.conf defaults more succinctly, modeled after mail/qmail-run.
* Add "reload" as a synonym for "cdb" in axfrdns, rbldns, \ 
and tinydns.
* Add "foo_postenv" for additional environment customization, for
    instance to run dnscache as a pure forwarder.
* Add "foo_log" booleans to enable or disable logging (enabled by default).
* Always run loggers as the "dnslog" user. This makes it simpler
    to define alternate loggers.
