This patch extends rte_security API with CPU-CRYPTO mode.
Crypto PMD that wants to support that functionality would need to:
1. claim RTE_CRYPTODEV_FF_SECURITY capability supported.
2. at device .probe() allocate and initialize security context (dev->
security_ctx).
3. implement at least the following functions inside rte_security_ops:
.session_create,
.session_get_size,
.session_destroy,
.process_cpu_crypto_sym
For data-path processing consumer of that API would have to maintain:
struct rte_security_ctx *ctx,
struct rte_security_session *sess
