78a7de300c make options.ExitNodes work
if your best choices happen to include any of your preferred exit nodes,
you choose among just those preferred exit nodes.

9e6f4a3029 revamp circuit node selection to use smartlists:
* now we know for sure if an acceptable node is available; we
    don't have to keep guessing and checking
  * we try options.EntryNodes first for picking the first node

e0952d0773 terminology shift:
directory is the string that dirserv.c and directory.c deal with
routerlist is routerinfo's that are bundled together in routers.c

rename some of the get_routerlist functions to set_routerlist

preparing to break into router.c for stuff the router does,
and routerlist.c for handling routerlist.

fix vicious bug in choose_good_exit_server that caused it to *skip over*
  pending circuits, and look only at *non-pending circuits*, when choosing
  a good exit node for the new circuit.

f65e871bfd bugfix in exit node choice: we used to find the perfect exit node but then use the wrong one.
bugfix in connection_ap_can_use_exit: it was using the wrong port
bugfix: the OP now handles a port of '*' correctly when the IP is not
  yet known and it's trying to guess whether a router's exit policy
  might accept it.
we now don't ever pick exit routers which will reject *:*
attach_circuit now fails a new stream outright if it will never work.
when you get an 'end' cell that resolves an IP, now it will fail the                             circuit outright if no safe exit nodes exist for that IP.
don't try building a new circuit after an 'end' if a suitable one is
  already on the way.

f0cccc567e bugfix: don't ask for ->next of an expired circuit
bugfix: keep going when a circ fails in circuit_n_conn_open
        (make circuit_enumerate_by_naddr_nport obsolete)
bugfix: make circuit_n_conn_open only look at circ's that start at us
bugfix: only try circuit_n_conn_open if we're an OP. Otherwise we
        expect connections to always already be up.
bugfix: when choosing path length, pay attention to whether the directory
        says a router is down.
bugfix: when picking good exit, skip routers which are known to be down
        (more work needs to be done on this one)

a8eaa79e03 Improved exit policy syntax; basic client-side DNS caching.
- Exit policies now support bitmasks (18.0.0.0/255.0.0.0) and bitcounts
  18.0.0.0/8.  Policies are parsed on startup, not when comparing to them.

- desired_path_len is now part of an opaque cpath_build_state_t structure.

- END_REASON_EXITPOLICY cells no longer include a port.

- RELAY_COMMAND_CONNECTED cells now include the IP address we've connected
  to.

- connection_edge now has a client_dns cache to remember resolved addresses.
  It gets populated by RELAY_COMMAND_CONNECTED cells and END_REASON_EXITPOLICY
  cells.  It gets used by connection_ap_handshake_send_begin.  We don't
  compare it to exit policies yet.

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.
