Samples: Add SMP pktqueue application

This sample application simulates a network router with several
interfaces which performs IP Header Validation(calculation
of CRC16 header checksum). Each interface is represented
by sender queue(initialized with packet headers) and receiver queue.
Every header first is fetched from sender queue, than the header
CRC16 is calculated, and finally if hashsum is correct
the header is stored in receiver queue.
Each interface is can be processed independently by multiple threads.

This application can be used for testing the correctness
of synchronization mechanisms on multi-core systems.
