* [plugin/proxy]: Return on WriteMsg err.

Followup PR on the heels of #2050. Short-circut and log on error from
`WriteMsg`. This will prevent code getting stuck on `ReadMsg` and allow
for easier debugging.

Also simply the `ReadMsg` calling code a little - remove double `Close` (already called above).

* Add @dilyevsky to reviewers.

Just create the sha256 inline so we know there are there.
Add a 'version' target in Makefile.release that prints the version so we
can double check that easily in the release script.

Every plugin needs to deal with EDNS0 and should call Scrub to make a
message fit the client's buffer. Move this functionality into the server
and wrapping the ResponseWriter into a ScrubWriter that handles these
bits for us. Result:

Less code and faster, because multiple chained plugins could all be
calling scrub and SizeAndDo - now there is just one place.

Most tests in file/* and dnssec/* needed adjusting because in those unit
tests you don't see OPT RRs anymore. The DNSSEC signer was also looking
at the returned OPT RR to see if it needed to sign - as those are now
added by the server (and thus later), this needed to change slightly.

Scrub itself still exist (for backward compat reasons), but has been
made a noop. Scrub has been renamed to scrub as it should not be used by
external plugins.

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).
