[tor-dev] Remote descriptor fetching

[Damian Johnson]

Hi Karsten, I've finally finished implementing stem's module for
remote descriptor fetching. Its usage is pleasantly simple - see the
example at the start of its docs...

https://stem.torproject.org/api/descriptor/remote.html
https://stem.torproject.org/_modules/stem/descriptor/remote.html
https://gitweb.torproject.org/stem.git/commitdiff/7f050eb?hp=b6c23b0

The only part of our wiki plans that I regretted needing to drop is a
local filesystem cache (the part that made me think twice was figuring
out when to invalidate cached resources). Otherwise this turned into a
pleasantly slick module.

Cheers! -Damian

PS. Where does an authority's v3ident come from? Presently I reference
users to the values in config.c but that's mostly because I'm confused
about what it is and how it differs from their fingerprint.
