* Speed up testing
* make notification run in the background, this recudes the test_readme
time from 18s to 0.10s
* reduce time for zone reload
* TestServeDNSConcurrent remove entirely. This took a whopping 58s for
... ? A few minutes staring didn't reveal wth it is actually testing.
Making values smaller revealed race conditions in the tests. Remove
entirely.
* Move many interval values to variables so we can reset them to short
values for the tests.
* test_large_axfr: make the zone smaller. The number used 64K has no
rational, make it 64/10 to speed up.
* TestProxyThreeWay: use client with shorter timeout
A few random tidbits in other tests.
Total time saved: 177s (almost 3m) - which makes it worthwhile again to
run the test locally:

This brings the total on 20s, and another 10s can be saved by fixing

Addresses a bug in the file plugin where SOA queries to zone delegations are
inappropriately returned the SOA for the delegating zone, and not a downward
referral to the delegated zone.
Here is an example of what I believe the expected downward referral in response
to a SOA query for a delegated zone should be (note that no SOA record is
returned):

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).

Abstract the caddy call and make it simpler.
See #3261 for some part of the discussion.
Go from:
~~~ go
func init() {
caddy.RegisterPlugin("any", caddy.Plugin{
ServerType: "dns",
Action: setup,
})
}
~~~
To:
~~~ go
func init() { plugin.Register("any", setup) }
~~~
This requires some external documents in coredns.io to be updated as
well; the old way still works, so it's backwards compatible.

* plugin/file: respond correctly to IXFR message
Respond with a sing SOA record to an IXFR request if the SOA serials
match.
The added test fails on the current code with:
~~~
=== RUN TestIxfrResponse
--- FAIL: TestIxfrResponse (0.00s)
secondary_test.go:122: Expected answer section with single RR
FAIL
exit status 1
~~~
And obviously passes with the new code. This should cut down on the
weird number of zone transfers that I was seeing. At some point IXFR
support might be cool.

Various fixes to make things less flaky:

function to see if that helps

Simplify the locking, remove the reloadMu and just piggyback on the
other lock for accessing content, which assumes things can be move
underneath.
Copy the Apex and Zone to new vars to make sure the pointer isn't
updated from under us.
The releadMu isn't need at all, the time.Ticker firing while we're
reading means we will just miss that tick and get it on the next go.
Add rrutil subpackage and put some more generic functions in there, that
are now used from file and the tree package. This removes some
duplication.

After calling NewZone the number of records should be zero, but due to
how zone.All() was implemented so empty RRs would be added. This then
fails the == 0 check in xfr.go and put nil in the slice, this then
subsequently panics on the Len().
Fix this making All() smarter when adding records. Added little test to
enfore this.

* plugin/file: Rename do to walk, cleanup and document
* This renames Do to Walk to be more inline with Go standards. Also make
it return an error instead of a bool.
Also give give walk access to rrs. Alternatively e.m could be
exported, but just access the map of rrs should work as well. Another
alternative would be adding a whole bunch of helper functions, but
those need grab and return the data. Just having access to the rrs
should be easiest for most Walks.
* It adds Type and TypeForWildcard to show the different functions
