Comment:

 The first two parts of this commit are fine, but the changes in dirvote.c
 need to become conditional, and only happen when a new consensus method is
 provided.

 The problem is that the consensus-generation code in dirvote.c needs to be
 run in exactly the same way on all the authorities for all inputs, or else
 they can produce different outputs, which will make them not agree on the
 consensus.
