6927467bef Refactor parameter computation and add a helper function
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.

899d2b890b prop250: Don't use {0} to init static struct -- causes warning on clang.
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.

d43646e191 prop250: Fix unit tests about the RSA fingerprint check
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.

Also, fix a time parsing overflow on platforms with 32bit time_t

056b6186ad prop250: Use RSA identity digest instead of fingerprint
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.

0c26a6db7e prop250: Parse votes and consensus
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.

Avoid disclosing exit IP addresses in exit policies by default
From 0.2.7.2-alpha onwards, Exits would reject all the IP addresses
they knew about in their exit policy. But this may have disclosed
addresses that were otherwise unlisted.

Now, only advertised addresses are rejected by default by
ExitPolicyRejectPrivate. All known addresses are only rejected when
ExitPolicyRejectLocalInterfaces is explicitly set to 1.
