Konstantin Ananyev 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.).
