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.
