* 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
* 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.
Fixes#415
* PR comments
Fix the delegation handling in the *file* and *dnssec* middleware.
Refactor tests a bit and show that they are failling.

Fix wildcard test - should get no answer from empty-non-terminal
* Changed reference to Caddy over to CoreDNS
* Removing references to caddy
* Fixed misleading error message to reference coredns

Muscle memory is resulting in "make clean" commands.

* More "Caddy" cleanup
When looking for a name in tree, return wether we got to a longer one -
if so we had an ent. Add tests + dnssec tests and refactor the tests as
well a bit.
