a0b0d16981 Add an ap_bridge function to do a socketpair and skip socks.
This allows us to do a directory connection *through* tor just
as if we're doing it as an application.

Make ap_conns tolerate it when the application sends stuff before
The socks handshake is done (it just buffers it).

Tell directory_initiate_command the length of the payload (because
it might include nuls).

Add a directory_has_arrived function to, for example, start building
the rendezvous service descriptor.

56dfc3151f work around a tsocks bug
when an AP connection dies early, be sure to do a socks reject
for it. if you just hang up, tsocks goes into an infinite loop.

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.

419a672222 holding until flush was borked
we were never writing anything when hold_open_until_flushed was set,
since conn_write returns early if marked_for_conn is set.

seems a bit better now.

a1e4c6dc85 Fix assertion failure spotted by arma.
Apparently, when a DNS failure was already cached, then when we tried
to mark the exit connection as closed, we'd try to remove it from the
pending queue anyway, and hit an assert.  Now, we put failed-resolve
connections in a separate state so that mark_for_close does the right
thing.

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.

Jan 18 04:11:43.312 [warn] connection_edge_send_command(): no circ. Closing.

i think it was while sending a connected relay cell back.
reason for having the circ gone is still not known. presumably the end cell
arrived at just the right time.
