5d9256a367 but only close the new conn if one of the earlier helper nodes
that we mark up is actually reachable, fast enough, etc to use.

c1145138ea but only close it if we have marked an earlier helper as up.
that way we don't close it too needlessly.

60cd03069a when we connect to a helper node for the first time, close
that connection and its circuits. this lets us go back to
using the old helper nodes rather than immediately using
the last one in the list.

f46c135fac when we succeed at connecting to a helper that we've never connected
to before, mark all the previous helpers as up. This is handy if the
network went away and then returned.

case, but many edge cases still need testing.

Also, when picking the helper node for a given circuit,
exclude the circuit's exit from your choices.

58366ffd24 when we changed from log_fn to debug/info/notice/warn/err,
we screwed up the formatting in wild and unpredictable ways.

fix it before it becomes convention to format logs in wild and
unpredictable ways.

still need to do src/common/ someday.

ea7fe0c267 Fix a bug found by Lasse Overlier: when we were making internal circuits
(intended to be cannibalized later for rendezvous and introduction
circuits), we were picking them so that they had useful exit nodes. There
was no need for this, and it actually aids some statistical attacks.

7aae63994f Recover better from TCP connections to Tor servers that are broken but
don't tell you (it happens!); and rotate TLS connections once a week.

1) If an OR conn becomes more than a week old, make it obsolete.
2) If it's obsolete and empty, kill it.
3) When an OR makes a second connection to you, allow it.
4) If we want to send a new create cell, but the best conn we've
   got is obsolete, and the router is 0.1.1.9-alpha-cvs or later, ask
   for a new conn instead.
5) When we time out on circuit building on the first hop, make that
   connection obsolete.

f824fb5f83 Bugfix: it looks like some middleman circuits were spending the
first few moments of their existence in CIRCUIT_STATE_OPEN, then
when Alice sent an extend request for a Tor that they're not connected
to, they switched to CIRCUIT_STATE_OR_WAIT and spent the rest of
their sorry little lives in that state, even when the connection
was established and they were shuttling relay cells back and forth.

And I'm not going to backport this (yet), because somehow it worked!

61ea516885 Check for named servers when looking them up by nickname;
warn when we'recalling a non-named server by its nickname;
don't warn twice about the same name.

Fix a bug in routers_update_status_from_networkstatus that made nearly
all clients never update routerinfo_t.is_named.

Try to list MyFamily elements by key, not by nickname.

Only warn about names that we generated ourself, or got from the local
user.

On TLS handshake, only check the other router's nickname against its
expected nickname if is_named is set.
