134266b984 Change the condition on the nonlive timeout counting.

cf2afcd707 Fix typos and comments, plus two bugs
A) We were considering a circuit had timed out in the special cases
where we close rendezvous circuits because the final rendezvous
circuit couldn't be built in time.
B) We were looking at the wrong timestamp_created when considering
a timeout.

feccaa5c83 Choose early circuit idle timeout better.
Don't discard all circuits every MaxCircuitDirtiness, because the
user might legitimately have set that to a very lower number.

Also don't use up all of our idle circuits with testing circuits,
since that defeats the point of preemptive circuits.

6eba08e22f Use our variable directly for timeout.

113ba0e727 make some bug 1090 warnings go away
When we excluded some Exits, we were sometimes warning the user that we
were going to use the node regardless. Many of those warnings were in
fact bogus, because the relay in question was not used to connect to
the outside world.

Based on patch by Rotor, thanks!

8c29b7920a Add some fixes after discussion with Nick.
- Refactor geoip.c by moving duplicate code into rotate_request_period().
- Don't leak memory when cleaning up cell queues.
- Make sure that exit_(streams|bytes_(read|written)) are initialized in all
  places accessing these arrays.
- Read only the last block from *stats files and ensure that its timestamp
  is not more than 25 hours in the past and not more than 1 hour in the
  future.
- Stop truncating the last character when reading *stats files.

The only thing that's left now is to avoid reading whole *stats files into
memory.
