Add integration test with erratic. For this erratic now also returns an
autopath searchpath. This tests the whole chain; i.e registring a
searchfunction and calling that from autopath.
This tests does a autopathing domain and a non-autopathing one.
* 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
