New controller event "clients_seen" to report a geoip-based summary

of which countries we've seen clients from recently. Now controllers
like Vidalia can show bridge operators that they're actually making
a difference.

guessing the wrong parts of our address as our address.

Tor has received and validated a new consensus networkstatus.

is received, if Tor needs to fetch certificates.)

These events apply only to streams entering Tor (such as on a SOCKSPort,
TransPort, or so on). They are not generated for exiting streams.
4.1.14. Per-country client stats
The syntax is:
"650" SP "CLIENTS_SEEN" SP TimeStarted SP CountrySummary CRLF
We just generated a new summary of which countries we've seen clients
from recently. The controller could display this for the user, e.g.
in their "relay" configuration window, to give them a sense that they
are actually being useful.
Currently only bridge relays will receive this event, but once we figure
out how to sufficiently aggregate and sanitize the client counts on
main relays, we might start sending these events in other cases too.
TimeStarted is a quoted string indicating when the reported summary
counts from (in GMT).
The CountrySummary keyword has as its argument a comma-separated
set of "countrycode=count" pairs. For example,
650-CLIENTS_SEEN TimeStarted="Thu Dec 25 23:50:43 EST 2008"
650 CountrySummary=us=16,de=8,uk=8
