* update docs
* plugins: use plugin specific logging
Hooking up pkg/log also changed NewWithPlugin to just take a string
instead of a plugin.Handler as that is more flexible and for instance
the Root "plugin" doesn't implement it fully.
Same logging from the reload plugin:

* update docs
* better doc
* Update all plugins to use plugin/pkg/log
I wish this could have been done with sed. Alas manually changed all
callers to use the new plugin/pkg/log package.
* Error -> Info
* Add docs to debug plugin as well
- 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
}
dnstap tcp://127.0.0.1:6000 full
errors stdout
}
tested with dnsperf tool
* don't spam Travis + valid dnstap payload
* log instead of fmt
* Revert "log instead of fmt"
This reverts commit 88f09c3939.
* log the right way
* log the final way
* minor enhancements
