When we are loading state info from disk, never believe any date in the future.  Doing so can keep us from retrying guards, rotating onion keys, storing bandwidth info, etc.  Fixes bug 434, and others. Backport candidate, once it has been tested.

99bfb1bebe If there's a never-before-connected-to guard node in our list,
never choose any guards past it. This way we don't expand our 
guard list unless we need to. [Bugfix in 0.1.2.x]

I'm not sure if this will solve all our problems, but it is at least
something.

237cdfdf48 if we already have a bridge in our state file, it won't be
in the networkstatuses, so we'll mark it unusable when we
load it, and then when we get a new routerinfo for it, we'll
still think it's unusable. fix that.

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.

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.

   - Ditto with RelayBandwidth*.
   - 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().
