69347f48e0 Disable consensus methods before 25.
Consensus method 25 is the oldest one supported by any stable
version of 0.2.9, which is our current most-recent LTS.  Thus, by
proposal 290, they should be removed.

This commit does not actually remove the code to implement these
methods: it only makes it so authorities will no longer support
them.  I'll remove the backend code for them in later commits.

fa70aabb62 dirauth: Recalculate voting schedule at first vote
Commit e67f4441eb introduced a safeguard against
using an uninitialized voting schedule object. However, the dirvote_act() code
was looking roughly at the same thing to know if it had to compute the timings
before voting with this condition:

  if (!voting_schedule.voting_starts) {
    ...
    dirvote_recalculate_timing(options, now);
  }

The sr_init() function is called very early and goes through the safeguard
thus the voting schedule is always initilized before the first vote.

That first vote is a crucial one because we need to have our voting schedule
aligned to the "now" time we are about to use for voting. Then, the schedule
is updated when we publish our consensus or/and when we set a new consensus.
From that point on, we only want to update the voting schedule through that
code flow.

This "created_on_demand" is indicating that the timings have been recalculated
on demand by another subsystem so if it is flagged, we know that we need to
ignore its values before voting.

Fixes #24186

7ee0a2b9aa sr: Don't use a dynamic voting schedule
The exposed get_voting_schedule() allocates and return a new object everytime
it is called leading to an awful lot of memory allocation when getting the
start time of the current round which is done for each node in the consensus.

Closes #23623

90a6fe318c Vote on 'proto' lines and include them after 'v' lines.
(Despite the increased size of the consensus, this should have
approximately zero effect on the compressed consensus size, since
the "proto" line should be completely implied by the "v" line.)

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.

b3b4ffce2e prop250: Add memory and disk state in new files
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.

df99ce2395 No longer advertise or negotiate any consensus method before 13.
Implements proposal 215; closes ticket 10163.

Why?  From proposal 215:

   Consensus method 1 is no longer viable for the Tor network.  It
   doesn't result in a microdescriptor consensus, and omits other
   fields that clients need in order to work well.  Consensus methods
   under 12 have security issues, since they let a single authority
   set a consensus parameter.
...
   For example, while Tor 0.2.4.x is under development, authorities
   should really not be running anything before Tor 0.2.3.x.  Tor
   0.2.3.x has supported consensus method 13 since 0.2.3.21-rc, so
   it's okay for 0.2.4.x to require 13 as the minimum method.  We even
   might go back to method 12, since the worst outcome of not using 13
   would be some warnings in client logs.  Consensus method 12 was a
   security improvement, so we don't want to roll back before that.
