Clean up dependency on github.com/golang/protobuf (#5222)
This PR cldean up remaining left over of github.com/golang/protobuf in coredns,
as github.com/golang/protobuf has been deprecated.

Note the github.com/golang/protobuf is now only indirectly
used by external libraries. Manually updating coredns' dependency to futher clean up has been tried.
However, it was not possible as external library usages of github.com/golang/protobuf are too interleaved.

This PR fixes 4939.

plugin/dnstap: remove custom encoder (#4242)
* plugin/dnstap: remove encoder*.go

Those files reimplemented parts of the dnstap spec, we can just use the
dnstap functions for that. This leaves all the queuing that is enabled
and drops messages if the dnstap reader can't keep up. In the new code
flush() would never return an error (at least I couldn't make it do so),
so the reconnect functionally is moved to kick off when we get write
errors.

Some smaller cosmetic changes as well, `d.socket` is now `proto`, which
makes the dial() function smaller.

Total testing time is now <1s (which was the impetus to look into this
plugin *again*).

See #4238
The buffered channel needs to be sized correctly, as we may need to do
some queing if the dnstap reader can't keep up.

plugin/dnstap: various cleanups (#4179)
* plugin/dnstap: various cleanups

A recent issue made me look into this plugin, I suspect various other
cleanups (hopefully deletion of code) can be made as well

Remove identical functions ToClientQuery etc, and just use tap.Message
as the base type in plugin. Keep msg/ for a few helper functions that
may proof useful.

This remove the whole test directory as we will just check the things we
are interested in which gives much better feedback and keeps that code
closer together.

tapwr dir is also not needed, writer_test.go was just duplicating the
tests already done. This moves writer.go to the top directory.

Make the only user of dnstap, the forward plugin, use the newer code
also remove the test, a better test there would be a full e2e test to
see the correct thing happens.

Cleanup the Tapper interface and move it to dnstapio where it belongs,
remove higher level interfaces that are not used. This remove
dnstap.Tapper and dnstap.IORoutines.

Use the standard mechanism for getting access to a plugin and remove
shuffling the plugin into the context.

all: simply registering plugins (#3287)
Abstract the caddy call and make it simpler.

See #3261 for some part of the discussion.

Go from:

~~~ go
func init() {
       caddy.RegisterPlugin("any", caddy.Plugin{
               ServerType: "dns",
               Action:     setup,
       })
}
~~~

To:

~~~ go
func init() { plugin.Register("any", setup) }
~~~

This requires some external documents in coredns.io to be updated as
well; the old way still works, so it's backwards compatible.

Clean up tests logging (#1979)
* Clean up tests logging

This cleans up the travis logs so you can see the failures better.

Older tests in tests/ would call log.SetOutput(ioutil.Discard) in
a haphazard way. This add log.Discard and put an `init` function in each
package's dir (no way to do this globally). The cleanup in tests/ is
clear.

All plugins also got this init function to have some uniformity and kill
any (future) logging there in the tests as well.

There is a one-off in pkg/healthcheck because that does log.

45ef657d36 Increase performance of Dnstap plugin (#1280)
- added dnstapEncoder object which incapsulates marshalling of dnstap
   messages to protobuf and writing data to connection

 - dnstapEncoder writes data directly to connection object. It doesn't
   use the framestream's "write" method, because it writes data to
   intermediate buffer (bufio.Writer) which leads to unnecessary
   data copying and drops the performance

 - dnstapEncoder reuses a preallocated buffer for marshalling dnstap
   messages. Many messages are added to the same buffer. They are
   separated with a "frame length" 4-byte values, so the buffer content
   is writen to connection object in the format compatible with
   framestream library

 - added test which guarantees that dnstapEncoder output is the same
   as framestream Encoder output

 - the performance increase is about 50% in (dio *dnstapIO) serve() method
   of dnstap plugin. The overall coredns performance increase is about 10%
   in the following configuration:

   .:1053 {
       erratic {
           drop 0
           truncate 0
           delay 0
