Bug 25903: Perform accounting for new CIRC_BW fields.

Two new values in each direction. DELIVERED counts valid end-to-end circuit
data that is accepted by our end and OVERHEAD counts the slack unused data in
each of the relay command cells for those accepted cells.

Control port changes are in the next commit.
