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)

- Exit policies now support bitmasks (18.0.0.0/255.0.0.0) and bitcounts
18.0.0.0/8. Policies are parsed on startup, not when comparing to them.
- desired_path_len is now part of an opaque cpath_build_state_t structure.
- END_REASON_EXITPOLICY cells no longer include a port.
- RELAY_COMMAND_CONNECTED cells now include the IP address we've connected
to.
- connection_edge now has a client_dns cache to remember resolved addresses.
It gets populated by RELAY_COMMAND_CONNECTED cells and END_REASON_EXITPOLICY
cells. It gets used by connection_ap_handshake_send_begin. We don't
compare it to exit policies yet.

is a the first step in computing hops one step at a time. Next, we move
the responsibility for calling onion_extend_cpath into circuit.c
(Later, we may want to special-case onion_extend_cpath to treat entry
and exit routers differently.)

Also:
- Refactor socks request into a separate struct
- Add a separate 'waiting for circuit' state to AP connections
between 'waiting for socks' and 'open'.
Arma: can you check out the XXX's I've added to connection_edge? I may
be mishandling some async and close logic.

Allow some slop (currently 3 minutes) when checking certificate validity.
Change certificate lifetime from 1 year to 2 days. Since we
regenerate regularly (we regenerate regularly, right??), this
shouldn't be a problem.
Have directories reject descriptors published too far in the future
(currently 30 minutes). If dirservs don't do this:
0) Today is January 1, 2000.
1) A very skewed server publishes descriptor X with a declared
publication time of August 1, 2000.
2) The directory includes X.
3) Because of certificate lifetime issues, nobody can use the
skewed server.
4) The server fixes its skew, and goes to republish a new descriptor Y
with publication time of January 1, 2000.
5) But because the directory already has a "more recent" descriptor X,
it rejects descriptor "Y" as superseded!
This patch should make step 2 go away.
