dp_core: Introduce offloads module

Smart nics may have ability to parse and act the Vrouter tunneled packets.

So, according to the Vrouter tunnels, aka MPLSoGRE, MPLSoUDP, and VXLAN, the
inner packet 5-tupples and the outer packet specifications, the HW can do
some actions. For example, the HW can detect MPLSoGRE packets and to do RSS
on the inner packet 5-tupples or just tag the packets based on the packet HW parser.

Using this HW feature the Vrouter parformance can be improved.

Add a Vrouter offloads module to use the described HW ability.

dpdk: Implement Rx offloads module

Now, when the user specifies "--offloads" in the dpdk command line,
the next RX offloads will accelarate the RX path:

1. RSS on inner 5-tupple for MPLSoGRE packets.
2. Destination my outer IP lookup.
3. MPLS nexthop lookup.
4. VXLAN nexthop lookup.
5. Inner flow lookup.

btable: optimize entry address calculation

The btable uses division and modulo calculations, which are quiet
expensive in the most platforms, for the entry address calculations.

In case the allocation limit of a btable is power of 2 number,
the calculations can be optimized to use simple bit calculations.

Optimize the entry address calculations in the aforementioned case.
