Comment(by Sebastian):

 Some comments on your notes:

  * I think that's a good idea, but probably for a later patch. I was
 aiming for that in my heartbeat work, but that got interrupted by
 microdescriptors as an actual deliverable.
  * per-country (or geoip or entrystatistics) (all mean the same thing, and
 yes this is very confusing) seem to use the same behaviour as bridge
 statistics now. Not sure if that is intended.
  * The way we are "forgetting" geoip stats is that we re-initialize them
 to be empty when they are enabled next time. This re-initialization sets
 start_of_bridge_stats_interval in geoip.c to now, and in
 geoip_bridge_stats_write() everything that was recoreded before
 start_of_bridge_stats_interval gets removed. That does not look like
 fantastic design, but should probably get cleaned up in a later patch.
