* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error
* Rename AddMiddleware to AddPlugin
* Readd AddMiddleware to remain backwards compat

block chaos queries, unless the chaos or proxy middleware is loaded. We
respond with REFUSED.
This removes the need for each middleware to do this class != ClassINET
if-then.
Also make config.Registry non-public.

Upstream allows file structured like /etc/resolv.conf. Update docs.
Fixes #709

* core: hide registerHandler
Remove RegisterHandler and just make it implicit when we look at the
handler compilation step.
* Rename GetHandler to just Handler
Update callers and make auto check Hander in OnStartup.
* Up test coverage in erratic
* up test coverage

* cidr everywhere: check all middleware
Add tests for cidr in only that middleware that already tests for this.
Check the other ones manually (and put reverse in the tests cases
anyway).
Make etcd setup_test run without +build etcd tag - it is not needed
for this test - move rest of the code to lookup_test.go.
Cleanup proxy test a bit and remove TempDir as there is test.TempFile
that does the same thing.
Fixes #909
* coredns package
* Fix test compile

* core: replace GetMiddleware
See the discussion in #881. GetMiddleware would add a `nil` middleware
to the callstack thereby breaking functionality.
This PR drops it in favor of RegisterHandler which is a completely
standalone registry for middleware that want to let it self know to
other middleware.
Currenly *autopath* uses this to call *kubernetes*'s AutoPath method
for dynamic autopathing.
* Drop GetMiddleware
* Register metrics
* drop the panic

Add some docs about normalize.Host and normalize.Name. They are used
correctly in the middleware even though they are somewhat confusing,
esp when you copy from ServerBlockKeys in your middleware.

* kubernetes/reverse: remove deadcode
* deadcode in errors and kubernetes removed
* unnecessary conversion
* constants
* proxy: time.Since()
* simplications
* static check
* Disable test/external_test

* middleware/file: don't reload zone when SOA isn't changed
Give Parse an extra argument which is the SOA's serial, if > 0 we check
against the just parsed SOA and then just return.
Most notable use is in reload.go which is both used in the file and auto
middleware.

(#547)
This fix fixes import path from
`github.com/miekg/coredns`
->
`github.com/coredns/coredns`
|

By defining and using an proxy.Exchanger interface we make the proxy
more generic and we can then fold back httproxy into proxy.
This overrides #463 and #473 and should make futures extensions rather
trivial
* Add docs that talk about `protocol` and how to set it.
* middleware/proxy: rename New to NewLookup
It's used as a Lookup mechanism not as a completely new proxy,
reflect that in the name.
* Set maxfails to 3 by default when looking up names.
Most of the changes have been copied
from https://github.com/johnbelamaric/coredns/pull/1/files

This checks if the next middleware to be called is nil, and if so returns
ServerFailure and an error. This makes the next calling more robust and
saves some lines of code.
Also prefix the error with the name of the middleware to aid in
debugging.

Close the reader, stop leaking file descriptors.

Do the same thing as in etcd and give the option of externally resolving
CNAME. This is needed when CoreDNS is a proxy as well is serving zones.

Be more explicit in the logs when a notify fails.
New notify error message looks like:
2016/11/07 18:21:42 [ERROR] Notify for zone "example.org." was not accepted by "8.8.8.8:53": rcode was "SERVFAIL"
Correctly pick up secondaries
When multiple secondary are specified make sure they are picked up.
Fixes #393 #398

* add extra test
* middleware/auto: fix crash when calling empty handler
Don't call the next middleware, we should be auth. for this zone
getitng into this path we should respond with ServFail.
Fixes #388

Don't panic on a non-existent directory. Add test for it as well.

* middleware/metrics: add more metrics
middleware/cache:
Add metrics for number of elements in the cache. Also export the total
size. Update README to detail the new metrics.
middleware/metrics
Move metrics into subpackage called "vars". This breaks the import
cycle and is cleaner. This allows vars.Report to be used in the
the dnsserver to log refused queries.
middleware/metrics: tests
Add tests to the metrics framework. The metrics/test subpackage allows
scraping of the local server. Do a few test scrape of the metrics that
are defined in the metrics middleware.
This also allows metrics integration tests to check if the caching and
dnssec middleware export their metrics correctly.
* update README
* typos
* fix tests

Add auto-load middleware that automatically picks up zones.
Every X seconds it will scan for new zones.
Add tests and documentation.
Make 'make test' use -race.
