Re-tune mempool parametes based on testing on peacetime: use smaller chuncks, free them a little more aggressively, and try very hard to concentrate allocations on fuller chunks.  Also, lots of new documentation.

7239262f71 Don't tell anybody, but we're going OO here. This patch splits
circuit_t into origin_circuit_t and or_circuit_t.  I fixed some
segaults; there may be more.  We still need to move more rendezvous
stuff into subtypes.

This is a trial run for splitting up connection_t; if the approach is
insane, please say so soon so we can do something smarter.

Also, this discards the old HALF_OPEN code, which nobody seems to
want.

fe221f3dff Start the process of treating internal circuits and exit circuits
separately. It's important to keep them separate because internal
circuits have their last hops picked like middle hops, rather than like
exit hops. So exiting on them will break the user's expectations.

- Stop cannibalizing internal circuits for general exits, and stop
  cannibalizing exit circuits for rendezvous stuff.

- Don't let new exit streams attach to internal circuits.

- When deciding if we have enough circuits for internal and for exit,
  don't count the wrong ones.

- Treat predicted resolves as predicted port 80 exits.

ec83652357 Logic to implement rendezvous/introduction via unknown servers.
- Add a new extend_info_t datatype to hold information needed to
  extend a circuit (addr,port,keyid,onion_key).  Use it in cpath and
  build_state.  Make appropriate functions take or return it instead of
  routerinfo_t or keyid.

- #if 0 needless check in circuit_get_by_edge_conn; if nobody triggers this
  error in 0.1.0.10, nobody will trigger it.

- Implement new hidden service descriptor format, which contains "extend
  info" for introduction points, along with protocol version list.
  - Parse new format.
  - Generate new format
  - Cache old and new formats alongside each other.
  - Directories serve "old" format if asked in old way, "newest available"
    format if asked in new way.
  - Use new format to find introduction points if possible; otherwise fall
    back.  Keep nickname lists and extendinfo lists in sync.
  - Tests for new format.

- Implement new "v2" INTRODUCE cell format.
  - Accept new format
  - Use new format if we have a versioned service descriptor that says the
    server accepts the new format.

- Add documentation for functions and data types.

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.

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.

79fc52170e For hidden services: handle INTRODUCE2, send ESTABLISH_INTRO, RENDEZVOUS1.
Also:
- Add a pending final cpath element to build_state
- Rename S_RENDEZVOUSING to S_CONNECT_REND
- Add [CS]_REND_JOINED
- Split out logic to initialize cpath crypto objects.
- Have circuits/cpaths remember the KH element from their handshake, so they
  can use it for other authentication later. (As in ESTABLISH_INTRO)
