Revise logic used to flush state to disk. Now, we try to batch non-urgent changes so that we do not do too many writes, and we save very-non-urgent changes every once in a rare while, and we never save more than once per second.

try to rebuild long-term connections to directory authorities, and
directory authorities no longer try to rebuild long-term connections to

to look at it more carefully to avoid flapping, and we likely need to
wait til 0.1.1.x is obsolete.

474c60b743 Cleanup on time-relaqted constants. New conventions: 
1) Surround all constants by (parens), whether we'll be using them
     in a denominator or not.
  2) Express all time periods as products (24*60*60), not as multiplied-out
     constants (86400).
  3) Comments like "(60*60) /* one hour */" are as pointless as comments
     like "c = a + b; /* set c to the sum of a and b */".  Remove them.
  4) All time periods should be #defined constants, not given inline.
  5) All time periods should have doxygen comments.
  6) All time periods, unless specified, are in seconds.  It's not necessary
     to say so.

To summarize, the old (lack of) style would allow:

  #define FOO_RETRY_INTERVAL 60*60 /* one hour (seconds) */
  next_try = now + 3600;

The new style is:

  /** How often do we reattempt foo? */
  #define FOO_RETRY_INTERVAL (60*60)

  next_try = now + RETRY_INTERVAL;

652e1899ac "How about 'never'? Does 'never' work for you?" 
Weasel says circuit_get_by_conn is his main timesink.  Most of its
users were just checking whether OR conns had circuits, so add a
circuit count to OR conns, and check that. One was
circuit_about_to_close_conn, which was doing an O(n^2) series of calls
to get all circs on an OR conn, so make an O(n) function for that.
Finally, circuit_get_by_edge_conn was using it as a sanity test that
has been around for a while but never found any actualy insanity, so
kill that.

circuit_get_by_conn is finally dead, which is good, since it was never
sane to begin with.

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.

d2400a5afd Introduce a notion of 'internal' circs, which are chosen without regard 
to the exit policy of the last hop. Intro and rendezvous circs must
be internal circs, to avoid leaking information. Resolve and connect
streams can use internal circs if they want.

New circuit pooling algorithm: make sure to have enough circs around
to satisfy any predicted ports, and also make sure to have 2 internal
circs around if we've required internal circs lately (with high uptime
if we've seen that lately).

Split NewCircuitPeriod config option into NewCircuitPeriod (30 secs),
which describes how often we retry making new circuits if current ones
are dirty, and MaxCircuitDirtiness (10 mins), which describes how long
we're willing to make use of an already-dirty circuit.

Once rendezvous circuits are established, keep using the same circuit as
long as you attach a new stream to it at least every 10 minutes. (So web
browsing doesn't require you to build new rend circs every 30 seconds.)

Cannibalize GENERAL circs to be C_REND, C_INTRO, S_INTRO, and S_REND
circ as necessary, if there are any completed ones lying around when
we try to launch one.

Re-instate the ifdef's to use version-0 style introduce cells, since
there was yet another bug in handling version-1 style. We'll try switching
over again after 0.0.9 is obsolete.

Bugfix: when choosing an exit node for a new non-internal circ, don't take
into account whether it'll be useful for any pending x.onion addresses --
it won't.

Bugfix: we weren't actually publishing the hidden service descriptor when
it became dirty. So we only published it every 20 minutes or so, which
means when you first start your Tor, the hidden service will seem broken.

324b192f68 Make Tor use Niels Provos's libevent instead of it's current 
poll-but-sometimes-select mess.  This will let us use faster async cores
(like epoll, kpoll, and /dev/poll), and hopefully work better on Windows
too.

There are some fairly nasty changes to main.c here; this will almost
certainly break something.  But hey, that's what alphas are for.

when an application request comes in during this state, be

and if it works, begin making circuits.

Put the check-if-requested-exitrouter-will-reject-us code in the
circuit_attach loop, so it gets checked periodically and not just
once at the beginning. This is useful in case the routerlist changes,
but also in case the address gets resolved into something that we learn

57536f138a Fetch running-routers. 
Split logic to initiate dirfetch, running-routers fetch, and
descriptor post.  arma: There are some XXXs here that raise design
questions which we should solve before the next release.

The biggest problem is this: Right now, the directory is about 50X as
large as running-routers uncompressed, and about 36X as large
compressed.  Assuming:

    - everybody gets the compressed version of everything,

    - everybody gets cached directories from random dirservers and
      uncached r-r from authdirservers

    - everybody downloads r-r at the same rate they now download dirs,

then using r-r from will *increase* authdirserver directory bandwidth usage
if there are significantly more caches than authdirservers.

I think it's safe to leave this in for now, since there aren't 3x36 caching
dirservers, but we should make everybody with a dirport cache running-routers
soon.  But I could be wrong.
