Comment (by dgoulet):
Latest branch with code rebased on master and improvement: `prop250_v4`.
This branch has few new things.
* A random number is now always hashed `H(RN)` so we avoid leaking bytes
from our PRNG to the network.
* Add SR flag to the vote indicating if the vote participates in the
protocol
* Parse votes and populate an object in the `networkstatus_t` object. Once
done, we only handle those commits once we are sure a vote is valid and
from known authority (we weren't doing that before).
* Refactor some functions to be able to support the last bullet above and
improve naming on some functions.
Few things are missing that I'll get to it:
* Consensus params for the number of participants.
* Torrc option to disable SR support (basically making the dirauth not
adding the SR flag to the vote).
* Some issues with the disk state also because we know rely on the RSA
fingerprint of a dirauth.
