reinstatement of some WJH comments, removal of some responses from
viktor and add authenticated in one spot where authentication is
required because that's the point of TLSA usage.
lots of comments, and a bit of text discussing "indeterminate"
(I have a path forward now)
added better text about servfail and bogus depending on the resolver type
clean up the text around the error handling and external resolver discussion
attempt at making a validating resolver result list
minor wording changes
Rewording of the dnserr section a bit
minor discovery rewording
Merge branch 'master' of github.com:vdukhovni/ietf
