Move all (almost all) Go files in middleware into their
own packages. This makes for better naming and discoverability.
Lot of changes elsewhere to make this change.
The middleware.State was renamed to request.Request which is better,
but still does not cover all use-cases. It was also moved out middleware
because it is used by `dnsserver` as well.
A pkg/dnsutil packages was added for shared, handy, dns util functions.
All normalize functions are now put in normalize.go
Make the receiver a pointer so that the uptdateStubZones map update will
retain the stubzones found, unlike the current case where the update
will be applied and then promptly forgotten, because it is working on a
copy.
Add test/etcd_test.go to test a large part of the code. This didn't
catch the chaos middleware hack though. The chaos middleware zones are
now *not* automatically added. You have to take care of that by yourself
(docs updates).
When using debug queries and falling through to the next middleware in
etcd, restore the original (with o-o.debug) query before passing it on.
* middleware/etcd: reverse addresses
Implement reverse (PTR) addresses. Update the documentation on how to
configure test. Added tests as well.
Fixes: #157#159
* Cleanup readme a little
With this you can retreive the raw data that the etcd middleware
used to create the reply. The debug data is put in TXT records
that are stuffed in the CH classs. This is only enabled if you
specify `debug` in the etcd stanza.
You can retrieve it by prefixing your query with 'o-o.debug.'
For instance:

Put error back in the correct place in the directives.go. Also don't
make it a pointer. If it *is* a pointer the buildstack function does
not correctly set the Next Handler. Don't understand *why* this is
different from Caddy. Anyway this fixes it, with the caveat that
the error log file is now openend earlier in the startup.
Fixes#127
For prometheus use the plain value, not a pointer and change all usages.
Allow AXFR to be requested over udp as well and some other more log
printed when commencing an AXFR.
Make the CH middleware actually work. Needs a bit of a hack to route
the fake version.bind and friends zone to the correct handler. Fiddle
with the order in directive.go so that CH queries get logged as well.
Secondly add class rewriting to the rewrite middleware handler and also
log the class by default.
Full implementation, DNS (and in the future DNSSEC). Returns answer in a
hopefully standards compliant way.
Testing with my miek.nl zone are included as well.
This should correctly handle nodata, nxdomain and cnames.
This implements stubzones in the same way as SkyDNS. This
also works with multiple configured domains and has tests.
Also add more configuration parameters for TLS and path prefix and
enabling stubzones. Run StubUpdates as a startup command to keep up to
date with the list in etcd.
