b67a5ba498 lower the reachability timeout, so we're more likely to act
quickly if a server stops being reachable.

1fc5eb329b We screwed up in anticipating how to add new dirservers:
Old servers won't realize they're supposed to stay connected
to the new dirservers, so they'll expire connections to them,
but that means the dirservers will list them as unreachable.

So the fix is to stop requiring an open connection when deciding
if a server is reachable. This makes us slightly less accurate,
but at least it will work.

43a4f8c7f3 Be more aggressive about throwing away expired router descriptors: they are of no use to anybody. Better still: dont serve expired descriptors by fingerprint. The only people who ask for them are busted 0.1.1.10 Tors that will throw them away and re-request them after 30 minutes.

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   got is obsolete, and the router is 0.1.1.9-alpha-cvs or later, ask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.

      to see whether caches support v2 stuff.

- Parse, cache, and serve network-status objects properly.

  here could be more memory-efficient.
