       One-Call function for Fapi_PcrExtend

       Performs an extend operation on a given PCR.

           TSS2_FAPI_RC_TRY_AGAIN if an I/O operation is not finished yet and this function needs
           to be called again.
           TSS2_FAPI_RC_PATH_NOT_FOUND if a FAPI object path was not found during authorization.
           TSS2_FAPI_RC_KEY_NOT_FOUND if a key was not found.
           TSS2_FAPI_RC_GENERAL_FAILURE if an internal error occurred.
           TSS2_FAPI_RC_AUTHORIZATION_UNKNOWN if a required authorization callback is not set.
           TSS2_FAPI_RC_AUTHORIZATION_FAILED if the authorization attempt fails.
           TSS2_FAPI_RC_POLICY_UNKNOWN if policy search for a certain policy digest was not
           successful.
           TSS2_ESYS_RC_* possible error codes of ESAPI.
           TSS2_FAPI_RC_NOT_PROVISIONED FAPI was not provisioned.
           TSS2_FAPI_RC_BAD_PATH if the path is used in inappropriate context or contains illegal
           characters.

   Fapi_PcrExtend_Finish (FAPI_CONTEXT * context)
       Asynchronous finish function for Fapi_PcrExtend
