For the 1.2.1 release we didn't upload the sha256 files. I've added
an echo, but some testing suggests that the files are created, so the
problem lays somewhere else.

Add a new upload section that sets the content type correctly and POST
the files as text/plain.

* Update setup.go

Revert this one change, so this can be merged.

* Add regression test for broken DNS truncation

With the latest changes to the implementation, request.Scrub() returns
invalid response messages which are larger than the advertised buffer
size. This commit adds a failing test for that.

* Add benchmark for response truncation

* request: re-adjust size for edns0 RR

Cherry-picked the test and benchmark commits from #1962 and make the
failing test not fail, by adding minimal fix in request.go.

This makes size 12 bytes smaller if we need to add back the OPT RR in
the message.

Closes: #1962

This downloads gometalinter (which is now breaking in the CI tests).
Also the goimports target is run with ||true, so nothing will break
if this flags anything (done because of gofmt changes in between
release).

Probably I will setup something to use github's linter API:

* Document current limitations of loop

* Update README.md

The Onstartup loop wouldn't call break after the first success, thereby
sending the query multiple times and halting the process.

Some small other optimizations as well.

* New plugin: loop

Add a plugin that detects loops. It does this by sending an unique query
to our selves. If we see the query more than twice we stop the process.
If there isn't a loop, the plugin disables it self and becomes a noop
plugin.

* plugin/erratic: add axfr support

Add support for axfr. This to fix and test long standing axfr issues
that are hard to test if we don't support it directly in coredns.

The most intriguing feature is withholding the last SOA from a response
so the client needs to wait; drop (no reply) and delay is also
supported. All TTLs are set to zero.

Add simple tests that checks if first record is a SOA.

* 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.

Fixes #1960

Log and returns an error when the name rewrite creates a name that is
illegal. Add test in name_test.go to see if an error is returned.

Possible followup could be the only check this if a name-rewrite is
done.
