c0308cd895 ipsec: rework SA replay window/SQN for MT environment
With these changes functions:
  - rte_ipsec_pkt_crypto_prepare
  - rte_ipsec_pkt_process
 can be safely used in MT environment, as long as the user can guarantee
 that they obey multiple readers/single writer model for SQN+replay_window
 operations.
 To be more specific:
 for outbound SA there are no restrictions.
 for inbound SA the caller has to guarantee that at any given moment
 only one thread is executing rte_ipsec_pkt_process() for given SA.
 Note that it is caller responsibility to maintain correct order
 of packets to be processed.

4d7ea3e145 ipsec: implement SA data-path API
Provide implementation for rte_ipsec_pkt_crypto_prepare() and
rte_ipsec_pkt_process().
Current implementation:
 - supports ESP protocol tunnel mode.
 - supports ESP protocol transport mode.
 - supports ESN and replay window.
 - supports algorithms: AES-CBC, AES-GCM, HMAC-SHA1, NULL.
 - covers all currently defined security session types:
        - RTE_SECURITY_ACTION_TYPE_NONE
        - RTE_SECURITY_ACTION_TYPE_INLINE_CRYPTO
        - RTE_SECURITY_ACTION_TYPE_INLINE_PROTOCOL
        - RTE_SECURITY_ACTION_TYPE_LOOKASIDE_PROTOCOL

For first two types SQN check/update is done by SW (inside the library).
For last two type it is HW/PMD responsibility.

1e0ad1e36d ipsec: add SA data-path API
Introduce Security Association (SA-level) data-path API
Operates at SA level, provides functions to:
    - initialize/teardown SA object
    - process inbound/outbound ESP/AH packets associated with the given SA
      (decrypt/encrypt, authenticate, check integrity,
      add/remove ESP/AH related headers and data, etc.).

9f7b43141c lib: introduce IPsec library
Introduce librte_ipsec library.
The library is supposed to utilize existing DPDK crypto-dev and
security API to provide application with transparent IPsec processing API.
That initial commit provides some base API to manage
IPsec Security Association (SA) object.
