b9d37a2d58 Add a new controller event type that allows controllers to get all 
server descriptors that were uploaded to a router in its role as authoritative
dirserver.

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   got is obsolete, and the router is 0.1.1.9-alpha-cvs or later, ask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

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.

cdc912714e I love the smell of C in the morning. Make router-download rules smarter (download more so long as we dont duplicate existing requests; relaunch at staggered intervals); relaunch one a minute or on failure; reset 60 minutes; always open 3 requests if we can; add authority opinion to networkstatus; make naming rule correct. There is a remaining bug where we retry servers too quickly; We need to look at that harder.

5c6c88e76d More stuff for new directories. 
- Distinguish v1 authorities (all currently trusted directories) from
  v2 authorities (all trusted directories).
    - Add configuration option for which dirs are v1 authories.
    - Add configuration option for whether to be a v1 authority.
    - Make trusted dirserver selection functions take options to
      choose which functionality we need.
    - Remove option when getting directory cache to see whether they
      support running-routers; they all do now.  Replace it with one
      to see whether caches support v2 stuff.

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

- Serve compressed groups of router descriptors.  The compression logic
  here could be more memory-efficient.

54a6a8f0ef Start implementing the server side of the new directory protocol. 
Probably very buggy, since I can't actually run an authdir.

Features
- Generate and publish new network-status format
- Code to cache and re-serve network-status objects generated by others.
- Publish individual descriptors (by fingerprint, by "all", and by
  "tell me yours.")  [Still needs compression logic]
- Publish client and server recommended versions seprately.
- Add digest of descriptor to routerinfo_t, so we can track them better, and
  length, so we can server them more easily.

Cleanups
- Unify code to sign directory-like things
- Make resolve_my_address() able to tell you which name it wound up resolving.
- Unify code to store and serve directory-like things so it all uses
  cached_dir_t.
- Unify code to set the value of cached_dir_t objects.

a120cc20c1 Dirservers now do their own external reachability testing of each 
Tor server, and only list them as running if they've been found to
be reachable.

Dirservers also log trouble servers, but only start complaining loudly
after they've been up for an hour, to reduce false positives. We still
need to do something about the fact that it is quite loud when there
are many trouble servers.
