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.
