Declan Doherty 202d375c60 app/test: add cryptodev unit and performance tests
unit tests are run by using cryptodev_qat_autotest or
cryptodev_aesni_autotest from the test apps interactive console.

performance tests are run by using the cryptodev_qat_perftest or
cryptodev_aesni_mb_perftest command from the test apps interactive
console.

If you which to run the tests on a QAT device there must be one
bound to igb_uio kernel driver.
