Unit test cases are added for pdump library.
Primary process will act as server, forks a child secondary process.
Secondary process acts as client.
Server will do pdump init to serve any pdump client requests.
Server will create a vdev, send/receive packets continuously in a separate
thread.
Client will create virtual rings to receive the packet dump.
Client sends pdump enable/disable requests using either port id or device id.
Packet flow direction can be tx/rx/tx&rx.
In Server, appropriate pdump callbacks are triggered when packets are
transmitted/received.
Pdump packet is copied to client rings.

This will not work in 18.08, see http://patches.dpdk.org/patch/43102/
Can we perhaps make it a standard test-app function? It is already
duplicated in two places, this will make it third.
