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over again after 0.0.9 is obsolete.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.

9c8c90ec2f Sometime post 0.0.9, we should integrate an http proxy into Tor (maybe
as a third class of worker process), so we can stop shipping with the
beast that is Privoxy.

dcf8b18215 when the hidden service launches a rendezvous circ, make sure it
provides good uptime if any virtual_port of the service wants that.

49fe4cba74 when deciding if a port is handled and the port demands uptime, don't
consider it handled if there's a circ that fits but isn't high-uptime.

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.

84c81e0783 Annotate circuits w/ whether they aim to contain high uptime nodes and/or
high capacity nodes. When building circuits, choose appropriate nodes.

New config option LongLivedPorts to indicate application streams
that will want high uptime circuits.

When attaching a stream to a circuit, pay attention to its requirements.

This means that every single node in an intro rend circuit, not just
the last one, will have a minimum uptime.

Boost the min uptime from an hour to 24 hours.

f468ff04ea when we haven't fetched a directory yet, or the last time we
tried they were all unreachable, assume we are not connected to
the network.

when an application request comes in during this state, be
optimistic and assume we just reconnected. fetch a new directory
and if it works, begin making circuits.
