2147898577 Implemented router twins
I modified new_route so we don't pick twins back-to-back in the path.

I also had to patch my previous uses of connection_twin_get_by_addr_port()
because they assumed that "addr" and "port" would be the same for a twin
as for the original router.

267434bdea Implemented congestion control
Servers are allowed to send 100 cells initially, and can't send more until
they receive a 'sendme' cell from that direction, indicating that they
can send 10 more cells. As it currently stands, the exit node quickly
runs out of window, and sends bursts of 10 whenever a sendme cell gets
to him. This is much much much faster (and more flexible) than the old
"give each circuit 1 kB/s and hope nothing overflows" approach.

Also divided out the connection_watch_events into stop_reading,
start_writing, etc. That way we can control them separately.

ccdef66b68 new link padding scheme
we're now much more robust when bandwidth varies: instead of forcing a
fixed bandwidth on the link, we instead use what the link will give us,
up to our bandwidth.

through the cvs messages), and added my router on mosg.cl.cam.ac.uk to
the list of routers.

117cbeeaaf Implemented link padding and receiver token buckets
Each socket reads at most 'bandwidth' bytes per second sustained, but
can handle bursts of up to 10*bandwidth bytes.

Cells are now sent out at evenly-spaced intervals, with padding sent
out otherwise. Set Linkpadding=0 in the rc file to send cells as soon
as they're available (and to never send padding cells).

Added license/copyrights statements at the top of most files.

router->min and router->max have been merged into a single 'bandwidth'
value. We should make the routerinfo_t reflect this (want to do that,
Mat?)

As the bandwidth increases, and we want to stop sleeping more and more
frequently to send a single cell, cpu usage goes up. At 128kB/s we're
pretty much calling poll with a timeout of 1ms or even 0ms. The current
code takes a timeout of 0-9ms and makes it 10ms. prepare_for_poll()
handles everything that should have happened in the past, so as long as
our buffers don't get too full in that 10ms, we're ok.

Speaking of too full, if you run three servers at 100kB/s with -l debug,
it spends too much time printing debugging messages to be able to keep
up with the cells. The outbuf ultimately fills up and it kills that
connection. If you run with -l err, it works fine up through 500kB/s and
probably beyond. Down the road we'll want to teach it to recognize when
an outbuf is getting full, and back off.

0a3da3ae37 put in the support for 'router twins'
basically, a twin is a router which is different except it shares
the same keypair. so in cases where we want to find a "next router"
and all we really care is that it can decrypt the next onion layer,
then a twin is just as good.

we still need to decide how to mark twins in the routerinfo_t and in
the routers config file.

d982925593 Integrated onion proxy into or/
The 'or' process can now be told (by the global_role variable) what
roles this server should play -- connect to all ORs, listen for ORs,
listen for OPs, listen for APs, or any combination.

* everything in /src/op/ is now obsolete.
* connection_ap.c now handles all interactions with application proxies
* "port" is now or_port, op_port, ap_port. But routers are still always
  referenced (say, in conn_get_by_addr_port()) by addr / or_port. We
  should make routers.c actually read these new ports (currently I've
  kludged it so op_port = or_port+10, ap_port=or_port+20)
* circuits currently know if they're at the beginning of the path because
  circ->cpath is set. They use this instead for crypts (both ways),
  if it's set.
* I still obey the "send a 0 back to the AP when you're ready" protocol,
  but I think we should phase it out. I can simply not read from the AP
  socket until I'm ready.

I need to do a lot of cleanup work here, but the code appears to work, so
now's a good time for a checkin.

bd627daa40 First cut at cleaning out a lot of the extra stuff.
The summary here is that I'm requiring all developers to have
auto* (aclocal, autoconf, automake) installed on their machine.

Since different versions of auto* generate vastly different output,
I'm going to leave its output out of the repository. This means that
whenever you check out a repository, you need to run auto* to generate
a configure file, then run ./configure to get a Makefile, then build.

If you don't have auto* and can't get it, let me know (and I'll try to
convince you to develop on moria).

The benefit here is that while developers have a bit more work to keep
things straight, we can build snapshots that will install just about
anywhere (once we make configure.in work, that is ;)
