77a425d8b2 Remove some functions that were around for hupping log files. We handle
them already in do_hup() by marking our log files as temporary and then
rotating them in options_init_from_torrc().

1da454a42d when returning a list of circuits, don't return a list of the same
conn over and over. that's really bad for memory.

652e1899ac "How about 'never'? Does 'never' work for you?"
Weasel says circuit_get_by_conn is his main timesink.  Most of its
users were just checking whether OR conns had circuits, so add a
circuit count to OR conns, and check that. One was
circuit_about_to_close_conn, which was doing an O(n^2) series of calls
to get all circs on an OR conn, so make an O(n) function for that.
Finally, circuit_get_by_edge_conn was using it as a sanity test that
has been around for a while but never found any actualy insanity, so
kill that.

circuit_get_by_conn is finally dead, which is good, since it was never
sane to begin with.

fe221f3dff Start the process of treating internal circuits and exit circuits
separately. It's important to keep them separate because internal
circuits have their last hops picked like middle hops, rather than like
exit hops. So exiting on them will break the user's expectations.

- Stop cannibalizing internal circuits for general exits, and stop
  cannibalizing exit circuits for rendezvous stuff.

- Don't let new exit streams attach to internal circuits.

- When deciding if we have enough circuits for internal and for exit,
  don't count the wrong ones.

- Treat predicted resolves as predicted port 80 exits.

ea7fe0c267 Fix a bug found by Lasse Overlier: when we were making internal circuits
(intended to be cannibalized later for rendezvous and introduction
circuits), we were picking them so that they had useful exit nodes. There
was no need for this, and it actually aids some statistical attacks.

5c949fce51 Start obeying our firewall options more rigorously:
- If we can't get to a dirserver directly, try going via Tor.
  - Don't ever try to connect (as a client) to a place our firewall
    options forbid.
  - If we specify a proxy and also firewall options, obey the firewall
    options even when we're using the proxy: some proxies can only proxy
    to certain destinations.

7aae63994f Recover better from TCP connections to Tor servers that are broken but
don't tell you (it happens!); and rotate TLS connections once a week.

1) If an OR conn becomes more than a week old, make it obsolete.
2) If it's obsolete and empty, kill it.
3) When an OR makes a second connection to you, allow it.
4) If we want to send a new create cell, but the best conn we've
   got is obsolete, and the router is 0.1.1.9-alpha-cvs or later, ask
   for a new conn instead.
5) When we time out on circuit building on the first hop, make that
   connection obsolete.

f824fb5f83 Bugfix: it looks like some middleman circuits were spending the
first few moments of their existence in CIRCUIT_STATE_OPEN, then
when Alice sent an extend request for a Tor that they're not connected
to, they switched to CIRCUIT_STATE_OR_WAIT and spent the rest of
their sorry little lives in that state, even when the connection
was established and they were shuttling relay cells back and forth.

And I'm not going to backport this (yet), because somehow it worked!
