96759a609e streams are now 8 bytes, and are recognized by intermediate hops 
the OP only crypts the appropriate number of times depending on which
layer (hop on the path) it's for/from.

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.

7ed6c8bd39 introduced a periodic keepalive padding cell 
now tor can be run safely inside nat'ed areas that kill idle
connections; and the proxy can handle when you suspend your laptop
and then emerge hours later from a new domain.

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
