3d641bde0e Refine r10571: more work on bridge stuff.
- Only listen to responses for "authority" fetches if we're configured
    to use Bridges. Otherwise it's safe (and maybe smarter) to silently
    discard them like we used to.
  - React faster to download networkstatuses after the first bridge
    descriptor arrives.
  - Don't do dir fetches before we have any bridges, even when our 
    dirport is open.

af658b7828 More work towards making bridge users able to connect via bridges:
- demand options->Bridges and options->TunnelDirConns if 
    options->UseBridges is set.
  - after directory fetches, accept descriptors that aren't referenced by
    our networkstatuses, *if* they're for a configured bridge.
  - delay directory fetching until we have at least one bridge descriptor.
  - learn how to build a one-hop circuit when we have neither routerinfo
    nor routerstatus for our destination.
  - teach directory connections how to pick a bridge as the destination
    directory when doing non-anonymous fetches.
  - tolerate directory commands for which the dir_port is 0.
  - remember descriptors when the requested_resource was "authority", 
    rather than just ignoring them.
  - put bridges on our entry_guards list once we have a descriptor for them.
    When UseBridges is set, only pick entry guards that are bridges. Else
    vice versa.

6ede110c4d When choosing an entry guard for our circuit, avoid using guards

07bf274d98 Interim commit: new config options Bridge and UseBridges.
It is becoming increasingly clear to me that bridges should
be a special case of entry guards, not a whole separate pile
of nearly identical functions.

Initial version of circuit-based cell queues.  Instead of hammering or_conns with piles of cells, queue cells on their corresponding circuits, and append them to the or_conn as needed.  This seems to work so far, but needs a bit more work.  This will break the memory-use-limitation patch for begin_dir conns: the solution will be a fun but fiddly.

Node-picking fixes: Never warn when a down node is listed in a config option (bug 348); always warn when a node in a config option is unnamed.  Also, when entrynodes is configured, then build the guard list as: (parts of EntryNodes that were guards before), (the rest of EntryNodes), (the rest of the old guards).  This last point ensures that EntryNode users will get the EntryNodes they want with the minimum change to their guard list.

   - Decide to leave in the "hey, you didn't set end_reason!" BUG log message,
     but stop telling people to bug me personally.
   - Postpone strengthening assert_connection_ok(): it's important, but 
     it's also a good way to introduce weird bugs.
   - Move some expensive consistency checking from dns_free_all() into
     assert_cache_ok().

Improvement to last entry guards patch: track when we last attempted to connect to a node in our state file along with how long it has been unreachable.  Also clarify behavior of parse_iso_time() when it gets extra characters.

Refactor entry guard status logic a lot; allow more factors [like not
 having a Guard flag or being listed in ExcludeNodes] to render a guard
 "unlisted" (now called "unusable"); track guard down status (now
 called "unreachable") separately from is_running.

Add more warnings to the list of those we tolerate. Start using GCC attributes more, for better error checking and better code generation.

Refactor connection_t into edge, or, dir, control, and base subtypes.  This might save some RAM on busy exit servers, but really matters most in terms of correctness.

7239262f71 Don't tell anybody, but we're going OO here. This patch splits
circuit_t into origin_circuit_t and or_circuit_t.  I fixed some
segaults; there may be more.  We still need to move more rendezvous
stuff into subtypes.

This is a trial run for splitting up connection_t; if the approach is
insane, please say so soon so we can do something smarter.

Also, this discards the old HALF_OPEN code, which nobody seems to
want.

it is still the case that we ignore it with respect to entry guards
that we've already picked.

0071d67efd when only one router is labelled as a guard, and we've
already picked him, we would cycle endlessly picking him
again, being unhappy about it, and so forth.

now we specifically exclude guards when picking a new guard.
