Originally fips_validation tests treats them both as GCM test vectors. This patch introduce automatic test type recognition between the two: when plaintext length is 0 the prepare_gmac_xform and prepare_auth_op functions are called, otherwise prepare_gcm_xform and prepare_aead_op functions are called. - NIST GCMVS also specified externally or internally IV generation. When IV is to be generated by IUT internally IUT shall store the generated IV in the response file. This patch also adds the support to that.
