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.)

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.

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.
