State of the protocol. It's also saved on disk in fname. This data structure MUST be synchronized at all time with the one on disk.
Definition at line 41 of file shared_random_state.h.
| digestmap_t* commits |
A map of all the received commitments for this protocol run. This is indexed by authority RSA identity digest.

| unsigned int is_srv_fresh |
Indicate if the state contains an SRV that was just generated. This is used during voting so that we know whether to use the super majority rule or not when deciding on keeping it for the consensus. It is always set to 0 post consensus.
EDGE CASE: if an authority computes a new SRV then immediately reboots and, once back up, votes for the current round, it won't know if the SRV is fresh or not ultimately making it NOT use the super majority when deciding to put or not the SRV in the consensus. This is for now an acceptable very rare edge case.
