we add support for bridges

In the rare event that a user resumes activity after a period between the
"reduced connection timeout" and the full value, and that user has not set
reduced padding, this is a distinguisher on circuits that have been held idle
and open for that long.

(Briefly: "Sent" is sometimes unobservable, so we should use
"queued" as a reasonable proxy.)

(This is largely determined by reverse-engineering tor's current
behavior.)

Also explain what should happen if those assumptions are violated.

The main points here are:

  * We assume that flow measurements are unidirectional, so
    each side must make sure to send traffic.
  * So we restart our timer when sending, only.
  * We restart the timer whether we're sending real traffic or
    padding traffic.
  * The logic for `max(X,X)` timing  applies even though we aren't
    using a bidirectional trigger for timing.

This has already been discussed somewhat on a pad; now we can move
to an MR and fill in the missing parts.
