I grepped and hand-inspected the "it's" instances, to see if any
were supposed to be possessive. While doing that, I found a
"the the", so I grepped to see if there were any more.
Keep the base16 representation of the RSA identity digest in the commit object
so we can use it without using hex_str() or dynamically encoding it everytime
we need it. It's used extensively in the logs for instance.

Encoded commit has an extra byte at the end for the NUL terminated byte and
the test was overrunning the payload buffer by one byte.

The test_state_update() test would fail if you run it between 23:30 and
00:00UTC in the following line because n_protocol_runs was 2:
tt_u64_op(state->n_protocol_runs, ==, 1);
The problem is that when you launch the test at 23:30UTC (reveal phase),
sr_state_update() gets called from sr_state_init() and it will prepare
the state for the voting round at 00:00UTC (commit phase). Since we
transition from reveal to commit phase, this would trigger a phase
transition and increment the n_protocol_runs counter.
The solution is to initialize the n_protocol_runs to 0 explicitly in the
beginning of the test, as we do for n_reveal_rounds, n_commit_rounds etc.
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.

This patch makes us retain the intermediate list of K=V entries for
the duration of computing our vote, and lets us use that list with
a new function in order to look up parameters before the consensus
is published.
We can't actually use this function yet because of #19011: our
existing code to do this doesn't actually work, and we'll need a new
consensus method to start using it.
Closes ticket #19012.

See ticket #19132 for the clang/llvm warning.
Since voting_schedule is a global static struct, it will be initialized
to zero even without explicitly initializing it with {0}.
This is what the C spec says:
If an object that has automatic storage duration is not initialized
explicitly, its value is indeterminate. If an object that has static
storage duration is not initialized explicitly, then:
— if it has pointer type, it is initialized to a null pointer;
— if it has arithmetic type, it is initialized to (positive or unsigned) zero;
— if it is an aggregate, every member is initialized (recursively) according to these rules;
— if it is a union, the first named member is initialized (recursively) according to these rules.
Code has been changed so every RSA fingerprint for a commit in our state is
validated before being used. This fixes the unit tests by mocking one of the
key function and updating the hardcoded state string.

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.
