Comment (by teor):
I agree with Nick's answer to this question:
> It probably makes sense for there to be two different variants of the
function -- one that sorts by ipv6 and one that sorts by ipv4. The parts
of the two functions that would be shared in common should turn into a
third function that they both would call.
I don't mind so much about the interface between get_possible_sybil_list()
and dirserv_generate_networkstatus_vote_obj().
It seems like a good idea to me to get separate lists of IPv4 and IPv6
sybils. You could try to merge them before returning to
dirserv_generate_networkstatus_vote_obj(), but that might be hard. Or you
could just loop through each list separately, and call
rep_hist_make_router_pessimal() on them all.
