[messaging] RFC: async NaCl relay

[Max Skibinsky]

Gents, we recently open sourced a couple of our infrastructure projects,
and I'm hoping that it would be interesting to the folks here to review our
codebase with a fresh set of eyes.

The main project is a "dead-drop" communication relay built around the NaCl
library. The idea is to have interchangeable relays with a global address
space (hash of identity keys) that keeps pass-through messages in
memory-only storage and are automatically cleared after a few days.

We were fortunate to have Yevgeniy Dodis help us with the design of the
crypto-schema for this relay, yet obviously there is a noticeable distance
from theoretical security to a provably secure codebase. We have done a few
rounds of internal reviews so far - if this is something that interests
you, we would really appreciate any feedback at *crypto at vault12.io
