This one is a little tricky.  Our BEGIN_DIR implementation has a
 problem: the dirserv conns will decide they can flush all their data
 immediately, since the edge_conns will read greedily.
 
 For our 0.1.2 workaround, we track which or_conn a bridged dirserv
 conn is attached to, and stop writing when its outbuf is too full, and
 start writing again when the or_conn's outbuf empties out a little.
 
 This requires a bit of pointer management.  Let's hope it works.

Remove redundant check for whether _connection_write_to_buf_impl is called with a zlib and a non-directory connection: TO_DIR_CONN will already assert if it gets a non-dir connection.

cb472fc550 break out the big guns: reject dir requests much more
aggressively. my vidalia bandwidth graph, when rate limiting
to 32kB/s, has the "write" line constantly at 32kB. I can't
imagine what's going on with the relay latency but it can't
be good.

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.

6452aecedb when calling connection_get_by_identity_digest, don't do a memcmp
for non-OR conns. this should save a bit of time.

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   got is obsolete, and the router is 0.1.1.9-alpha-cvs or later, ask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.

be more fair on loaded Tor servers, and it might resolve our
Windows crash bug. It might also slow things down.

logs in cases where a calling function's log was downgraded and we wouldn't
get any log message otherwise.
