Use 64-bit interface statistics rather than doing custom 32-bit overflow handling.
When a link has a relatively high throughput, the 32-bit packet and byte counters could overflow multiple times between accounting runs.
To accommodate this limitation, directly use 64-bit interface statistics.
This also gets rid of the internal giga-word counters.
