6c61ed4fb5 Make options no longer a global variable. 
Now we can try setting an option but back out if it fails to parse, or
  if it's disallowed (e.g. changing RunAsDaemon from 1 to 0).

c66e4c4870 Flush more changes from sandbox 
- make clients cache directories and use them to seed their router lists
   at startup.  This means clients have a datadir again.
 - Introduce a global_write_bucket.  We need to respond better to exhausting
   it.
 - Remove the last vestiges of LinkPadding and TrafficShaping.
 - Configuration infrastructure support for warning on obsolete options.
 - Refactor directory header parsing to use smartlist_split_string.
 - Respond to content-encoding headers by trying to uncompress as appropriate.
 - Reply with a deflated directory when a client asks for "dir.z".
   (We could use allow-encodings instead, but allow-encodings isn't
   specified in HTTP 1.0.)

dc7951a5a7 a whole swath of fixes 
introduce an authdir_mode() macro to match the others.
don't initialize uptime to the number of seconds since 1970.
non-authoritative dirservers don't cache their directory on disk.
make only authdirservers use clique_mode.
only read approved-routers file if you're an authdirserver.
even authdirservers fetch a new directory in do_hup.
retry_all_connections() is now called retry_all_listeners().
router_parse_list_from_string() correctly reports the router number
  it's working on.
only call dirserv_add_own_fingerprint() and
   dirserv_add_descriptor() on startup if we're an authdirserver.
if AuthDir and !ORPort then fail.
if AuthDir and ClientOnly then fail.

a5ff0527e6 it turns out we weren't looking at the result from getsockopt(). 
now we do.
but i'm not sure it matters, since we also poll for reads, and if
there's an error with the connecting socket, poll is supposed to
return readable, so we should notice it then.

who knows.

2ba2f02181 Integrate the new "rephist" [rep(utation) hist(ory)] module to trace 
successful/failed connections, successful/failed extends, and
connection uptimes.

It's still not done: more tests are needed, and not everything calls
connection/circuit_mark_for_close properly.  This skews the results.

Also, there needs to be a 'testing' mode for non-OP ORs, where they
periodically build circuits just to test whether extends work.

Apparently, when a DNS failure was already cached, then when we tried

c5bbb571d2 Refactor mark_for_close, connection_edge_end and friends. Now, everybody 
who wants to shut down a connection calls connection_mark_for_close instead
of setting marked_for_close to 1.  This automatically removes the connection
from the DNS cache if needed, sends a RELAY END cell if appropriate, and can
be changed to do whatever else is needed.

Still to do:
  - The same for circuits, maybe.
  - Add some kind of hold_connection_open_until_flushed flag, maybe.
  - Change stuff that closes connections with return -1 to use mark_for_close,
    maybe.

c485725c5a Fix the dns bug: children weren't dying 
We were telling a child to die by closing the parent's file descriptor
to him. But newer children were inheriting the open file descriptor from
the parent, and since they weren't closing them, the socket never closed,
so the child never read eof, so he never knew to exit.

As a side effect to this bug, we were probably failing to properly close
connections to remote hosts, ORs, and OPs, after a dns child was born.

I'm surprised Tor worked at all.

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.

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.

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?

c336c99e60 Start of port to win32. Missing are: 
- signal support
  - forking for DNS farm
  - changes for async IO
  - daemonizing

In other words, some files still don't build, and the ones that do build,
do nonblocking IO incorrectly.

I'm also not checking in the project files till I have a good place
for them.
