e3adcbdb95 Big commit: clients start downloading and using network-statuses.
Only caches need to get running-routers; nobody needs to parse, store,
or use it.  Same for the router-status line in the directories.  Add
many #if 0's that can get removed once I'm convinced they don't
contain anything I'm forgetting.

Start all newly-parsed routers as non-running and non-valid; update
them from the list of network statuses.

Update all routers when a new networkstatus comes in.

After 3 tries for a networkstatus, clients give up until they're told
to try again.

29c57b54d4 Add functions to extend and compress new router store logic. (Basic idea: use a journal of newly received router descriptors, and periodically replace the old file. This avoids the "too many files" problem and the "too many rewrites" problem.)

3dc5e77b58 Numerous changes to move towards client-side v2 directories.
connection.c:
- Add some more connection accessor functions to make directory
  download redundancy checking work.

directory.c, or.h, router.c, routerlist.c:
- Start on logic to note when networkstatus downloads fail.

dirserv.c, routerlist.c, routerparse.c:
- Start maintaining an is_named field in routerstatus_t.  Don't
  actually look at it yet.

dirserv.c, routerlist.c:
- Remove expired networkstatus objects.

or.h:
- Make some booleans into bitfields
- Add prototypes

routerlist.c:
- Sort networkstatus list by publication time
- Function to remove old (older than 10 days) networkstatus objects.
- Function to set a list of routerinfo_ts' status info from the
  current set of networkstatus objects.
- Function to tell which routerinfos we need to download based no the
  current set of networkstatus objects.
- Do not launch a networkstatus download if a redundant one is in progress.

routerparse.c:
- Keep router entries in networkstatus sorted by digest.

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.

- Keep the signed descriptor inside routerinfo_t.  This makes

ef6c9d18e7 New circuit building strategy: keep a list of ports that we've used in the past 6 hours, and always try to have 2 circuits open or on the way
that will handle each such port. (We can extend this to include addresses
if exit policies shift to require that.) Seed us with port 80 so web
browsers won't complain that Tor is "slow to start up".

This was necessary because our old circuit building strategy just involved
counting circuits, and as time went by we would build up a big pile of
circuits that had peculiar exit policies (e.g. only exit to 9001-9100)
which would take up space in the circuit pile but never get used.

Fix router_compare_addr_to_addr_policy: it was not treating a port of *
as always matching, so we were picking reject *:* nodes as exit nodes too.

If you haven't used a clean circuit in an hour, throw it away, just to
be on the safe side.

This means after 6 hours a totally unused Tor client will have no
circuits open.
