This patch extend rte_flow API.
The purpose is to provide necessary programming interface for virtual
switch software (such as OVS) to take advantage of incoming device's
vSwitch acceleration capability when using DPDK as data plane.

Below is summary of changes:

1. Support to specify flow's destination as an ethdev interface.

Add action RTE_FLOW_ACTION_TYPE_ETHDEV_PORT, use port_id as the identification
of the destitation. A typical use case is, with a smart NIC used for vSwitch
acceleration, flow is defined to redirect packet between switch port that is
managed by a Port Representor.

2. Enhanced flow statistics query.
Enhanced action RTE_FLOW_ACTION_COUNT by adding last hit timestamp tracking which is
the requirement from OVS.

3. Add protocol headers which will be supported by incoming device.

New protocal headers include IPV4 ARP, IPV6 ICMP , IPV6 extent header.

4. Add packet modification actions which will be supported by incoming device.

Add new actions that be used to modify packet content with generic semantic:

RTE_FLOW_ACTION_TYPE_FIELD_UPDATE: update specific field of packet
RTE_FLWO_ACTION_TYPE_FIELD_INCREMENT: increament specific field of packet
RTE_FLWO_ACTION_TYPE_FIELD_DECREMENT: decreament specific field of packet
RTE_FLWO_ACTION_TYPE_FIELD_COPY: copy data from one field to another in packet.

All action use struct rte_flow_item parameter to match the pattern that going
to be modified, if no pattern match, the action just be skipped.
These action are non-terminating action. they will not impact the fate of the
packets, since pattern match is expected to be performed before packet be modified.

Note:
- The driver to demonstrate the new APIs is still in development, 
  but we hope it could be accepted early to make OVS integration smoothly.
- Testpmd command line support does not be included and will be submitted
  seperately in future.
