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)

Before we resolve the hostname, we don't know whether its IP will be accepted or rejected by the exit policy of each host. So we were only going with nodes that would certainly accept -- which
was just itys and poblano.
(This bug was hidden until now by the earlier port bug.)
(Actual bugfix pending on Nick's next commit, hopefully.)

* now we know for sure if an acceptable node is available; we
don't have to keep guessing and checking
* we try options.EntryNodes first for picking the first node

directory is the string that dirserv.c and directory.c deal with
routerlist is routerinfo's that are bundled together in routers.c
rename some of the get_routerlist functions to set_routerlist
preparing to break into router.c for stuff the router does,
and routerlist.c for handling routerlist.

never work.
fix vicious bug in choose_good_exit_server that caused it to *skip over*
pending circuits, and look only at *non-pending circuits*, when choosing
a good exit node for the new circuit.
bugfix: remove incorrect asserts in circuit_get_newest()
svn:r876
bugfix in connection_ap_can_use_exit: it was using the wrong port
bugfix: the OP now handles a port of '*' correctly when the IP is not
yet known and it's trying to guess whether a router's exit policy
might accept it.
we now don't ever pick exit routers which will reject *:*
attach_circuit now fails a new stream outright if it will never work.
when you get an 'end' cell that resolves an IP, now it will fail the circuit outright if no safe exit nodes exist for that IP.
don't try building a new circuit after an 'end' if a suitable one is
already on the way.
svn:r874
bugfix: keep going when a circ fails in circuit_n_conn_open
(make circuit_enumerate_by_naddr_nport obsolete)
bugfix: make circuit_n_conn_open only look at circ's that start at us
bugfix: only try circuit_n_conn_open if we're an OP. Otherwise we
expect connections to always already be up.
bugfix: when choosing path length, pay attention to whether the directory
says a router is down.
bugfix: when picking good exit, skip routers which are known to be down
(more work needs to be done on this one)
