Comment(by asn):

 Do we care about bridges giving out separate statistics for "normal"
 usage, and for pluggable transport usage? Can this harm anonymity? If we
 like doing this, we should spec. it.

 The implementation plan for providing client geoip statistics to bridge
 authorities could be something like: When using Extended ORPort, everytime
 we receive a client address through `USERADDR`, pass it to
 `geoip_note_client_seen()` like we are currently doing in
 `connection_or_set_state_open()`.
