[master] dnstap

4235.	[func]		Added support in named for "dnstap", a fast method of
			capturing and logging DNS traffic, and a new command
			"dnstap-read" to read a dnstap log file.  Use
			"configure --enable-dnstap" to enable this
			feature (note that this requires libprotobuf-c
			and libfstrm). See the ARM for configuration details.

			Thanks to Robert Edmonds of Farsight Security.
