Don't sign data we are not authoritative for. This adds an AuthWalk
which skips names we should not authoritative for. Adds a few tests to
check this is the case. Generates zones have been compared to
dnssec-signzone.
A number of changes have been made:
* don't add DS records to the apex
* NSEC TTL is the SOA's minttl value (copying bind9)
* Various cleanups
* signer struct was cleaned up: doesn't need ttl, nor expiration or
inception.
* plugin/sign: remove apex stuff from names()
This is never used because we will always have other types in the
apex, because we *ADD* them ourselves, before we sign (DNSKEY, CDS and
CDNSKEY).

* plugin/sign: a plugin that signs zones
Sign is a plugin that signs zone data (on disk). The README.md details
what exactly happens to should be accurate related to the code.
Signs are signed with a CSK, resigning and first time signing is all
handled by *sign* plugin.
Logging with a test zone looks something like this:
~~~ txt
