The *get* state query functions for the SRVs now only return const pointers
and the DEL action needs to be used to delete the SRVs from the state.

We assert on it using the ASSERT_COMMIT_VALID() macro in critical places
where we use them expecting a commit to be valid.

The prop250 code used the RSA identity key fingerprint to index commit in a
digestmap instead of using the digest.
To behavior change except the fact that we are actually using digestmap
correctly.

One of the last piece that parses the votes and consensus in order to update
our state and make decision for the SR values.
We need to inform the SR subsystem when we set the current consensus because
this can be called when loaded from file or downloaded from other authorities
or computed.
The voting schedule is used for the SR timings since we are bound to the
voting system.

This adds the logic of commit and SR values generation. Furthermore, the
concept of a protocol run is added that is commit is generated at the right
time as well as SR values which are also rotated before a new protocol run.

This commit introduces two new files with their header.
"shared_random.c" contains basic functions to initialize the state and allow
commit decoding for the disk state to be able to parse them from disk.
"shared_random_state.c" contains everything that has to do with the state
for both our memory and disk. Lots of helper functions as well as a
mechanism to query the state in a synchronized way.
