Comment(by andrea):

 Begin code review:

 How will we pick the fallback servers/how long is the list expected to be?
 In 5c51b3f1f0d4c394392aa6fce89bbe0960117771, for example, you're
 introducing router_get_fallback_dirserver_by_digest() that searches a
 smartlist, which was fine for the short list of trusted authorities, but
 in comments further up on this ticket I'm seeing numbers like 500 servers
 being bandied about, which makes me a bit nervous about linear-time
 searches.  Is this going to be so infrequent an operation it isn't worth
 worrying about, though?
