078c5ab617 leave the socks handshake on the inbuf until it's complete
this paves the way for supporting socks5 and other handshakes
it also removes those pesky AP-only variables from connection_t

also hacked a fix for a bug where some streams weren't ending properly --
maybe because marked connections weren't flushing properly?

9a33b59ece relay queues are obsolete (woo!)
they used to be used for
* queueing relay cells at the edge of the network, when windows are empty
* queueing relay cells that arrive after an onion but before the onion
  has been processed.
both of these uses are gone. so out they go.

1c6def292b remove dead code
circuits no longer queue more cells when the windows are empty --
they simply don't package it from the buffer if they're not going to want it.

we can restore this code later if we need to resume queueing.

e1d37ed6ab divorce circuit building from user connections
now we rebuild the circuit periodically (but only if it's been used),
and we can further abstract it to do incremental circuit building, etc.

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.
