 obfuscation protocol.

 Roger started the discussion [https://lists.torproject.org/pipermail/anti-
 censorship-team/2019-May/000015.html on our anti-censorship-team mailing
 list]. Relevant reading is the CCS'15 paper
 [https://censorbib.nymity.ch/#Wang2015a Seeing through Network-Protocol
 Obfuscation] and the S&P'16 paper
 [https://censorbib.nymity.ch/#Tschantz2016a SoK: Towards Grounding
 CensorshipCircumvention in Empiricism].

 Let's use this ticket to keep track of this effort.
