ab245746a9 Hey kids, guess why connection_mark_for_close() started giving an assert when called for an even-numbered line? Right, because I made it a bitfield, when it was really a line number. Why did I think it was a bitfield? A stale comment. Let that be a lesson to us all.

fba01c3cc0 bugfix: we were whining about using socks4 or socks5-with-local-lookup
even when they used an IP in the "virtual" range we designed exactly
for this case.

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.

6693031947 Use a separate type for "local view of router status". Also, even though I told arma there was no need, replace an ugly O ( n lg n ) algorithm with a nice O ( n ) algorithm when stepping through servers. Some ugliness is just too bad to stand.

87f6d526fe Refactor new directory code a bit. Keep a big list of rolled-up router status info, including # of download failures (not yet used). Update this list from networkstatuses when they arrive, then update routers from this list. Only download 128 routers at a time, to avoid gargantuan URLs.

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.

it has failed not only when the connection attempt fails, but also
if the conn reaches eof before we get a response that we're happy with.

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.

1b04f38145 subtle change to avoid some false positives:
if a server went down for six hours and then came back, we would
complain to it that it's unreachable. now we wait until the third
consecutive descriptor post that we thought it was unreachable,
before complaining to it.

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.
