       Points:               |    Sponsor:
-----------------------------+--------------------------------
 * Make directory mirrors (which FetchDirInfoEarly) fetch from fallback
 directory mirrors, before they try authorities
 * Modify directory_should_fetch_from_authorities():
   * move FetchDirInfoEarly to directory_fetches_dir_info_early, and make
 directory_fetches_dir_info_early fetch from the fallback directory mirrors
   * change DirPort_set to dir_server_mode() or similar (requires #12538)
 and move to directory_fetches_dir_info_early
   * move refuseunknown to directory_fetches_dir_info_early
 Directory mirrors shouldn't need a different schedule to fetch from
 fallback directory mirrors, they can simply fetch on their standard
 schedule.
