bind -> unbound/nsd

[christos%zoulas.com@localhost (Christos Zoulas)]

Hello,

The recent change of ISC/bind licensing from BSD to MPL for the
next release has provided us with an opportunity to re-evaluate
the preferred daemon status for NetBSD and DNS resolution. Board/Core
have decided not to import the next version of bind, and instead
import the current version of unbound/nsd.

If you feel that this creates problems for you, let us know.
Also you should be able to use newer versions of bind from pkgsrc.
We are not planning to de-support or remove bind for NetBSD-8.

Best,

christos
