descriptors have address 0.0.0.0 until directory fetch

Descriptors received from the controller via the POSTDESCRIPTOR directive are interpreted to have address 0.0.0.0. This is corrected at the time of the next periodic directory fetch, at which point the addr field of the routerinfo_t is populated with the correct address from the descriptor. Note that even if no descriptors with the same nickname or identity as the one received from the controller are received from the periodic directory fetch, the address of the descriptor received from the controller will apparently be changed to be the right one.

Indeed, this means that sending the HUP signal to the Tor process will always fix the problem, but ideally we should figure out why directory fetches are necessary to fix descriptors passed in from the controller.
