954570486f Resolve a FIXME: use identity comparison, not nickname comparison, to 
choose circuit ID types.  This is important because our view of "the
nickname of the router on the other side of this connection" is
skewed, and depends on whether we think the other rotuer is
verified--and there's no way to know whether another router thinks you
are verified.

For backward compatibility, we notice when the other router chooses
the same circuit ID type as us (because it's running an old version),
and switch our type to be polite.

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).
Use parse_line_from_str rather than parse_line_from_file.

fb2279b90b since we don't support truncateds much, don't bother sending them; 
just close the circ.

(this wasn't relevant before, because we were mis-handling destroys.)

0ba9ab5fb0 Add rendezvous-related metadata and code to circuits. Initially, we 
thought that a complicated adjunct structure would be necessary, but
it doesn't look that way anymore.

Of course, I might have forgotten something.

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.

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.
