Reduce the memory overhead in IP fragment management
- Deep-copy pkt.Data and hold it instead of shallow-copy (vv.Clone).
This allows the pkt's backing array, which includes the header portion,
to be freed.
- Remove fragHeap. The fragments are now held in holes struct instead.
- Stop reserving the initial capacity of holes slice.
