e6296a4e2f Refactor onion_generate_cpath to build cpaths one hop at a time. This 
is a the first step in computing hops one step at a time.  Next, we move
the responsibility for calling onion_extend_cpath into circuit.c

(Later, we may want to special-case onion_extend_cpath to treat entry
and exit routers differently.)

dafb0e6a6e Make AP connections wait for a circuit if none exists. 
Also:
  - Refactor socks request into a separate struct
  - Add a separate 'waiting for circuit' state to AP connections
    between 'waiting for socks' and 'open'.

Arma: can you check out the XXX's I've added to connection_edge? I may
be mishandling some async and close logic.

7604cfe61b Clock skew fixes. 
Allow some slop (currently 3 minutes) when checking certificate validity.

Change certificate lifetime from 1 year to 2 days.  Since we
regenerate regularly (we regenerate regularly, right??), this
shouldn't be a problem.

Have directories reject descriptors published too far in the future
(currently 30 minutes).  If dirservs don't do this:
    0) Today is January 1, 2000.
    1) A very skewed server publishes descriptor X with a declared
       publication time of August 1, 2000.
    2) The directory includes X.
    3) Because of certificate lifetime issues, nobody can use the
       skewed server.
    4) The server fixes its skew, and goes to republish a new descriptor Y
       with publication time of January 1, 2000.
    5) But because the directory already has a "more recent" descriptor X,
       it rejects descriptor "Y" as superseded!

This patch should make step 2 go away.

4139c1c86a - fixed a bug in the id switching code -- setgid has to happen before 
setuid, because after we setuid we don't have the priviledges we
  need to setgid anymore, duh.  merged switch_user() and
  switch_group() into switch_id(), since that code has to be wound
  together.

- return -1 from switch_id() if it's not defined to do anything else.

- moved daemoinize(), write_pidfile(), and switch_id() from main.c to
  util.c

b1eca56b77 added User and Group options -- if you set them, tor will try to 
setuid and setgid respectively, and die if it can't.

(If the User option is set, tor will setgid to the user's gid as well.)

This happens after the pidfile is created, so that in cases where tor
needs to be root to work with the pidfile, it will at least be able to
create it, although it won't be able to delete it.  That sucks, but
it's somewhat better than not being able to create the pidfile in the
first place.

4a66865d0b send the end cell when we realize we're going to end, 
not when we're closing the stream.

this lets us put a payload in the end cell if we want to,
to describe why we're closing the stream.

there are still some places where we don't send the end cell
immediately. i need to track them down. but it's a low priority,
since i've made it send the end cell when we close the stream if
we haven't already sent it.

If DebugLogFile is specified, log to it at -l debug
If LogFile is specified, log to it at the -l from the commandline
  (default info)
If no LogFile *and* not a Daemon, then log to stdout.
Make conn->s = -1 by default (this might break things)
When kill -USR1, prefer to log at INFO, but make sure they always see it.

9e5cafc395 first pass: obey log convention 
ERR is if something fatal just happened

WARNING is something bad happened, but we're still running. The bad thing
is either a bug in the code, an attack or buggy protocol/implementation
of the remote peer, etc. The operator should examine the bad thing and
try to correct it.
(No error or warning messages should be expected. I expect most people
to run on -l warning eventually.)

NOTICE is never ever used.

INFO means something happened (maybe bad, maybe ok), but there's nothing
you need to (or can) do about it.

DEBUG is for everything louder than INFO.

3d4ccb781a Refactor buffers; implement descriptors. 
'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.

40d0fca63a cleanups, bugfixes, more verbose logs 
Fixed up the assert_*_ok funcs some (more work remains)

Changed config so it reads either /etc/torrc or the -f arg, never both

Finally tracked down a nasty bug with our use of tls:
  It turns out that if you ask SSL_read() for no more than n bytes, it
  will read the entire record from the network (and maybe part of the next
  record, I'm not sure), give you n bytes of it, and keep the remaining
  bytes internally. This is fine, except our poll-for-read looks at the
  network, and there are no bytes pending on the network, so we never know
  to ask SSL_read() for more bytes. Currently I've hacked it so if we ask
  for n bytes and it returns n bytes, then it reads again right then. This
  will interact poorly with our rate limiting; we need a cleaner solution.

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.

22df330f14 Get directories working. 
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.

Roger: If you can answer the question with your name on it, you may
prevent a segfault before it happens. :)
