* plugin/rewrite: streamline the ResponseRule handling.
The functionality of a response rule is now completely encapsulated behind
a `ResponseRule` interface. This significantly simplifies the complete
processing flow, it enables more flexible response handling and it is possible
to eliminate lots of state flags, ifs and switches.
Based on the new flexibility the pull request also enables to support a
response name rewrite for all name rewrite types.
To be compatible, an explicit `answer auto` option is added to support
a best effort response rewrite (name and value).
Additionally now all name rewrite rules support additional name and value
reponse rewrite options.
Using this feature it is also possible now to rewrite a complete sub domain
hierarchy to a single domain name combined with a correct rewrite (#2389).

* For caddy v1 in our org
This RP changes all imports for caddyserver/caddy to coredns/caddy. This
is the v1 code of caddy.
For the coredns/caddy repo the following changes have been made:
* anything not needed by us is deleted
* all `telemetry` stuff is deleted
* all its import paths are also changed to point to coredns/caddy
* the v1 branch has been moved to the master branch
* a v1.1.0 tag has been added to signal the latest release

* plugin/route53/setup.go:124:28: session.New is deprecated: Use NewSession functions to create sessions instead. NewSession has the same functionality as New except an error can be returned when the func is called instead of waiting to receive an error until a request is made. (SA1019)
* test/grpc_test.go:25:69: grpc.WithTimeout is deprecated: use DialContext and context.WithTimeout instead. Will be supported throughout 1.x. (SA1019)
The first one isn't true, as this is set via ldflags. The rest is
minor. The deprecation should be fixed at some point; I'll file some
issues.

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.

* Fix some typos
Corect some words for reading more easily
* Update NOERROR response code
NOERROR is a response code so I revert the typo checking for it

* pkg/replace: make it more efficient.
Remove the map that is allocated on every write and make it more static,
but just defining a function that gets called for a label and returns
its value.
Remove the interface definition and just implement what is needed in our
case. Add benchmark test for replace as well.
Extend metadata test to test multiple values (pretty sure this didn't
work, but there wasn't a test for it, so can't be sure).
Update all callers to use it - concurrent use should be fine as we pass
everything by value.
Benchmarks in replacer:
new: BenchmarkReplacer-4 300000 4717 ns/op 240 B/op 8 allocs/op
old: BenchmarkReplacer-4 300000 4368 ns/op 384 B/op 11 allocs/op
Added benchmark function to the old code to test it.
~~~
func BenchmarkReplacer(b *testing.B) {
w := dnstest.NewRecorder(&test.ResponseWriter{})
r := new(dns.Msg)
r.SetQuestion("example.org.", dns.TypeHINFO)
r.MsgHdr.AuthenticatedData = true
b.ResetTimer()
b.ReportAllocs()
repl := New(context.TODO(), r, w, "")
for i := 0; i < b.N; i++ {
repl.Replace("{type} {name} {size}")
}
}
~~~
New code contains (of course a different one). The amount of ops is
more, which might be good to look at some more. For all the allocations
is seems it was quite performant.
This looks to be 50% faster, and there is less allocations in log
plugin:

* Fix EDNS0 compliance
Do SizeAndDo in the server (ScrubWriter) and remove all uses of this
from the plugins. Also *always* do it. This is to get into compliance
for https://dnsflagday.net/.
The pkg/edns0 now exports the EDNS0 options we understand; this is
exported to allow plugins add things there. The *rewrite* plugin used
this to add custom EDNS0 option codes that the server needs to
understand.
This also needs a new release of miekg/dns because it triggered a
race-condition that was basicly there forever.
See:
* https://github.com/miekg/dns/issues/857
* https://github.com/miekg/dns/pull/859
Running a test instance and pointing the https://ednscomp.isc.org/ednscomp
to it shows the tests are now fixed:

* Clean up tests logging
This cleans up the travis logs so you can see the failures better.
Older tests in tests/ would call log.SetOutput(ioutil.Discard) in
a haphazard way. This add log.Discard and put an `init` function in each
package's dir (no way to do this globally). The cleanup in tests/ is
clear.
All plugins also got this init function to have some uniformity and kill
any (future) logging there in the tests as well.
There is a one-off in pkg/healthcheck because that does log.
