a8d805e292 break out circ->rend_service 
(this breaks the compile; must fix things)

let alice react when she learns a new rendezvous descriptor

let alice launch intro and rend circuits and mark them with her query

f34e6da3e7 now circuit_get_newest returns an appropriate circ for your purpose 
connection_ap_handshake_attach_circuit attaches to a circ of the
right purpose

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)

d13857a3f0 put in hooks for alice and bob logic when circuits finish/fail 
let you specify the purpose of circuits you launch

bugfix: we used to be declaring the first successful circuit too                               early -- when the first hop finished. now we're more accurate.

0ba9ab5fb0 Add rendezvous-related metadata and code to circuits. Initially, we 
thought that a complicated adjunct structure would be necessary, but
it doesn't look that way anymore.

Of course, I might have forgotten something.

2ba2f02181 Integrate the new "rephist" [rep(utation) hist(ory)] module to trace 
successful/failed connections, successful/failed extends, and
connection uptimes.

It's still not done: more tests are needed, and not everything calls
connection/circuit_mark_for_close properly.  This skews the results.

Also, there needs to be a 'testing' mode for non-OP ORs, where they
periodically build circuits just to test whether extends work.

c5bbb571d2 Refactor mark_for_close, connection_edge_end and friends. Now, everybody 
who wants to shut down a connection calls connection_mark_for_close instead
of setting marked_for_close to 1.  This automatically removes the connection
from the DNS cache if needed, sends a RELAY END cell if appropriate, and can
be changed to do whatever else is needed.

Still to do:
  - The same for circuits, maybe.
  - Add some kind of hold_connection_open_until_flushed flag, maybe.
  - Change stuff that closes connections with return -1 to use mark_for_close,
    maybe.

 * clean up relay_crypt
 * use relay dummies if there's going to be a conflict with rh.recognized
 * check for a conflict when generating stream_ids
