23c193c065 if dns resolve is valid, but our exit policy rejects it or
the connect attempt fails immediately, we were trying to
double-remove it from the dns pending list.

i think this might have been The Bug.

facb5d4221 Reload rendezvous service keys on sighup; otherwise, we wind up with a
bunch of half-initialized services.  This should solve half of
weasel's current bug.  The crash is the other half.

do rend begin cells right,
send an introduction cell (sort of)
receive a rendezvous2 cell (sort of)

7793078dff alice can now look up bob's service descriptor,
choose an intro point, connect to it,
choose a rend point, connect to it and establish a cookie,
get an ack from the rendezvous point,
and know when both circs are ready for her.

APConns don't use conn->purpose anymore

don't initiate a renddesc lookup if one is already in progress

also fix a buffer overflow in nickname parsing (only exploitable
by the operator though)

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)
