c35373a2cf major overhaul: dns slave subsystem, topics
on startup, it forks off a master dns handler, which forks off dns
slaves (like the apache model). slaves as spawned as load increases,
and then reused. excess slaves are not ever killed, currently.

implemented topics. each topic has a receive window in each direction
at each edge of the circuit, and sends sendme's at the data level, as
per before. each circuit also has receive windows in each direction at
each hop; an edge sends a circuit-level sendme as soon as enough data
cells have arrived (regardless of whether the data cells were flushed
to the exit conns). removed the 'connected' cell type, since it's now
a topic command within data cells.

at the edge of the circuit, there can be multiple connections associated
with a single circuit. you find them via the linked list conn->next_topic.

currently each new ap connection starts its own circuit, so we ought
to see comparable performance to what we had before. but that's only
because i haven't written the code to reattach to old circuits. please
try to break it as-is, and then i'll make it reuse the same circuit and
we'll try to break that.

9d3e80a589 use a rbtree for replay detection, rather than linear search
when we had lots of new onions coming in, we were using 40% of
our time searching through the tracked_onions linked list.

bd97deb919 onions expire after a day, not an hour
this was a major faq, because it would fail with an error only on
the *server* side when the client-side time was wrong. the client would
simply not work.

8f18647a33 create cells are now queued and processed only when idle
we also queue data cells destined for a circuit that is
pending, and process them once the circuit opens

along with its collected data cells

121d029584 fix subtle race condition
If you weren't connected to a given router, and you made a directory
request to it simultaneously with a new web query that caused you to
want to connect to that OR... it would think you're already connected.

connections; and the proxy can handle when you suspend your laptop
and then emerge hours later from a new domain.

6934eb9f10 mozilla actually cares about the reply version
tor can now interface directly with mozilla, as a socks 4 host.
but note that mozilla does the dns resolution itself, so you're leaking
anonymity.

253f0f160e laying the groundwork for dynamic router lists
revamped the router reading section

reference counting for crypto pk env's (so we can dup them)

we now read and write pem pk keys from string rather than from FILE*,
  in anticipation of fetching directories over a socket
  (so now on startup we slurp in the whole file, then parse it as a string)

fixed a bug in the proxy side, where you could get some circuits
  wedged if they showed up while the connection was being made
