 A Tor instance should log a warning if traffic accounting is enabled and
 any of the following are true:

  * It is configured to operate two or more hidden services (e.g. there are
 two or more HiddenServiceDir lines in its configuration).
  * It is configured to operate at least one hidden service and run as a
 relay or bridge.

 This change attempts to address a possible user safety issue and can't
 break Tor in a subtle way, so I'm filing it for 0.2.3.x.
