Move dig(1) and needed DNS libraries into it's own source directory in
usr.bin/dig.

From the beginning when we started to remove unneeded nameserver code,
it was our goal to extract dig functionality from the bind sources,
for everyone's benefit as this is easier to reason about.

In total we removed about 2/3 or over 300.000 lines of code.

We kept the lib/ subdirectory layout but moved the content of bin/ to
the top from the old bind source directory.

Previous sources and history can be found in the src/usr.sbin/bind
Attic.

Proposed directory layout sounds good to sthen
