This PR adds a expiration jitter to spread out zone re-signing even

specific zone.

plugin/sign: fix signing of authoritative data (#3479)
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).

e14e053d3d create pkg/reuseport (#3455)
* create pkg/reuseport

Move the core server listening functions to a new package so plugins can
use them.

Also make *all* servers use the functions here; as only the udp/tcp
listeners where using SO_REUSEPORT (if available). This is the only
actual change in this PR; in it's core it's just a move of 2 files.

This can also be used to cleanup the dance we're doing now for
re-acquiring the sockets in e.g. the metrics plugins and the ready
plugin.

431c70e8b9 Correct some if/iff mixups (#3406)
This is a fixup for https://github.com/coredns/coredns/pull/3310 which
replaced some 'iff's with 'if' under the assumption they were typos.

I'm fairly confident they were "If and only if"
(https://en.wikipedia.org/wiki/If_and_only_if), which is commonly
shortened as "iff".

I've updated them to the full length 'if, and only if' for the sake of
readability.

pkg/log: add Clear to stop debug logging (#3372)
When reloading we need to disable debug output when the debug plugin is
removed from the config file. Add a `Clear` function to pkg/log and use
it in the server server.

Add test case in pkg/log, for actuall check I manually checked the
output by sprinkling some debug statements in the startup and checking
with sending SIGUSR1.

Also clear up the comments in pkg/log to remove the text about time
stamping.
