redo all the config files for the new format (we'll redo them again soon)
fix (another! yuck) segfault in log_fn when input is too large
tor_tls_context_new() returns -1 for error, not NULL
fix segfault in check_conn_marked() on conn's that die during tls handshake
make ORs also initialize conn from router when we're the receiving node
make non-dirserver ORs upload descriptor to every dirserver on startup
add our local address to the descriptor
add Content-Length field to POST command
revert the Content-Length search in fetch_from_buf_http() to previous code
fix segfault in memmove in fetch_from_buf_http()
raise maximum allowed headers/body size in directory.c

'buf_t' is now an opaque type defined in buffers.c .
Router descriptors now include all keys; routers generate keys as
needed on startup (in a newly defined "data directory"), and generate
their own descriptors. Descriptors are now self-signed.
Implementation is not complete: descriptors are never published; and
upon receiving a descriptor, the directory doesn't do anything with
it.
At least "routers.or" and orkeygen are now obsolete, BTW.

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?

your client exits if you're running a version not in the
directory's list of acceptable versions (unless you have a
config variable set to override).

Or at least, directories get generated, signed, download, and checked, with
nobody seeming to crash.
In config/*, added 'signing-key' blocks to dirservers and routers.or, so
that everyone will know about the directories' signing keys.
In or/directory.c, refrained from using a dirserver's signing key when
no such key is known; added more debugging output.
In or/main.c, added debugging output and fixed a few logic errors.
In or/routers.c, added debugging output and prevented a segfault on
routers_resolve_directory. The interleaving of arrays and lists on
routerinfo_t is still messy, but at least it seems to work again.
svn:r278
prkey is only fetched when it's needed
tor nodes who aren't dirservers now fetch directories and autoconnect
to new nodes listed in the directory
default role is a non-dirserver node
svn:r120
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
svn:r110
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.
svn:r50
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.
