adaf3d31e6 hidden service client connections were using some of their
60 seconds fetching the hidserv descriptor, which made them
more likely to fail on the first attempt, yet they work fine
on the second. so now give them extra time for the first try.

38be533c69 Handle unavailable hidden services better. We try each intro point
until none are left, then we try to refetch the descriptor. If it's
the same one we had before, then close streams right then. Whenever
a new stream arrives, even if it's right after, optimistically try
refetching the descriptor, just in case.

cfcc93296c bugfix for cvs: we were needing a rendezvous circ, so we cannibalized
a general circ, and called rend_client_rendcirc_has_opened(), which
called connection_ap_attach_pending(), which was needing a rendezvous
circ, so it cannibalized a general circuit, and called ...

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over again after 0.0.9 is obsolete.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.

c1dc17e6e2 put in initial support for ".nickname.exit" addresses, to let alice
decide what exit node to use; based on a patch by geoff goodell.

needs more work: e.g. it goes bananas building new circuits when the
chosen exit node's exit policy rejects the connection.
