and golang.org/x/text to v0.3.0, for the purpose of
align with go version 1.10.

Use binary search to find the minimal message size, that contains whole
RRs and fits the client's buffer. This is better then just setting
entire sections to `nil`. Extend the tests to test for additional and
answer section truncation. In the first case we *don't* set the TC bit.

This function now also set Compression to true.

make -f Makefile.doc

Drop prominent placement of SkyDNS, some cleanups

Caddy 0.10.11 is released. Fix CoreDNS to compile against that version.
This also helps people compiling CoreDNS and go getting non-vendored
deps.

* go 1.10: update travis and gofmt

fmt now complains about on file tls_test.go, fix that. Also remove
gofmt, as goimports also checks, so this was done twice.

Put go 1.9 and 1.10 in travis for the time being.

* goimports optional

* Revert "pkg/typify: empty messages are OtherError (#1531)"

This reverts commit fc1d73ff.

* plugin/cache: add failsafeTTL

If we can not see what TTL we should put on a message to be cached, use
5 seconds as minimal TTL. We used to apply the maximum TTL to these
  messages.

* add noendpoints option

* go fmt

* add upstream

* docs

* tests

* move file, auto, secondary to new upstream

* include context in request

Messages with nothing in them are considered OtherError, they can not
serve any purpose for normal clients (i.e. dyn update or notifies might
have a use for them).

Also update a test in the cache plugin, so that we explicitaly test for
this case.

* add namespace watch

* start ns watch, and add sync check

* plugin/forward: on demand healtchecking

Only start doing health checks when we encouner an error (any error).
This uses the new pluing/pkg/up package to abstract away the actual
checking. This reduces the LOC quite a bit; does need more testing, unit
testing and tcpdumping a bit.

* fix tests

* Fix readme

* Use pkg/up for healthchecks

* remove unused channel

* more cleanups

* update readme

* * Again do go generate and go build; still referencing the wrong forward
  repo? Anyway fixed.
* Use pkg/up for doing the healtchecks to cut back on unwanted queries
  * Change up.Func to return an error instead of a boolean.
  * Drop the string target argument as it doesn't make sense.
* Add healthcheck test on failing to get an upstream answer.

TODO(miek): double check Forward and Lookup and how they interact with
HC, and if we correctly call close() on those

* actual test

* Tests here

* more tests

* try getting rid of host

* Get rid of the host indirection

* Finish removing hosts

* moar testing

* import fmt

* field is not used

* docs

* move some stuff

* bring back health_check

* maxfails=0 test

* git and merging, bah

* review

* add upstream @self and loop count

* 1st round of feedback

* allow argless upstream

* update test

* readmes

* feedback

* prevent nil pointer when query frpc client that could not open

* add UT checking we can now safely request DNS query on an invalid hostname, query for gRPC connection

* fix ortograph

* fix format

* fix package declaration, fix UT - grpclogger, use fatalf, build pool with known addresses

* type, useless error check - after review

* Extend bind to allow multiple addresses. UTs added. Changes the log for server starting, adding address when available

* update readme for bind

* fixes after review

* minor fix on readme

* accept multiple BIND directives in blocserver, consolidate the addresses

* fixes after review - format logging server address, variable names

This fix enables goimports check and fixes several imports format
so that the import sections are prettier, e.g.:
```
 import (
-       "github.com/miekg/dns"
        "regexp"
        "strconv"
        "strings"
+
+       "github.com/miekg/dns"
 )
```

* Stop noisy modifications

* Review comments, tests

* More coverage

* vet

* Make it obvious new port name is not a typo

Remove `fallthrough` from the federation example in the README.  `fallthrough` isn't needed here and has no effect (federation has an implicit fallthrough for non-federated queries).  
It's inclusion is confusing.

Reloading should work (kill -TERM reload the coredns process), but a lot
of plugins can't handle it proper. Disable to reload plugin until we fix
(most) of the plugins

Pinged me, still interested in helping out \o/

This fix add a test case for case insensitive/preserving with
whoami plugin.

This fix is part of the effort for 1403.

* plugin/kubernetes: axfr

Hook up dynamic SOA serial by setting ResourceEventHandlerFuncs in
dnsController.

Add prototype of returns msg.Services via the Transfer function. Leave
expanding this to RRs out of scope for a bit.

* plugin/kubernetes: axfr

Respond to AXFR queries

* Fixing race condition

* Fixing instantiation of dnstest writer

* Updates from review

Forward still wasn't right; run make -f Makefile.doc, as well for good
measure.

Retweak this a little to make it slightly easier to *not* forget this,
but it is hardly perfect. Should probably make it an interface a plugin
can implement and then unblock if we see that interface.

We have OWNERS file throughout the repo. The top level OWNERS file
replaces the MAINTAINERS file (sans email addresses that is).

This should have everyone, but the process was quite manual. The rename
from middleware -> plugin also meant I had to do some extra digging on
who actually submitted the PR. I also double checked the current list of
people with commit access.

Every plugin now has an OWNERS, except *reverse*. I'll file a bug for
that.

* remove setdo

* gofmt
