This patch adds symmetric crypto data-path APIs for Cryptodev. Direct symmetric crypto data-path APIs are a set of APIs that provide more HW friendly enqueue/dequeue data-path functions as an alternative approach to ``rte_cryptodev_enqueue_burst`` and ``rte_cryptodev_dequeue_burst``. The APIs are designed for external libraries/applications that want to use Cryptodev as symmetric crypto data-path accelerator but not necessarily mbuf data-path centric. With the APIs the cycle cost spent on conversion from their data structure to DPDK cryptodev operations/mbufs can be reduced, and the dependency on DPDK crypto operation mempool can be relieved.
It is expected that the user can develop close-to-native performance symmetric crypto data-path implementations with the functions provided in this patchset.
