11d330be5e Tweaks to prevent obsolete restarting tors from hammering the dirservers. (1) Cache a received directory as soon as the signature checks out. (2) Treat a cached directory as "recent" based on its mtime. (3) If we have a recent directory, we dont need to fetch a newer one for DirFetchPostPeriod. This needs review!

e5049d5aa3 Remove routerinfo_t->is_trusted_dir, and all the twisted machinery used to
maintain it.

Have clients default to the nickname "client" in their certificates.

Give a less frightening warning on obsolete (pre-0.0.8) routerinfo_t's.

c66e4c4870 Flush more changes from sandbox
- make clients cache directories and use them to seed their router lists
   at startup.  This means clients have a datadir again.
 - Introduce a global_write_bucket.  We need to respond better to exhausting
   it.
 - Remove the last vestiges of LinkPadding and TrafficShaping.
 - Configuration infrastructure support for warning on obsolete options.
 - Refactor directory header parsing to use smartlist_split_string.
 - Respond to content-encoding headers by trying to uncompress as appropriate.
 - Reply with a deflated directory when a client asks for "dir.z".
   (We could use allow-encodings instead, but allow-encodings isn't
   specified in HTTP 1.0.)
