At this time only two complementary operations are supported by the enclave: copying a value from outside the enclave into a default buffer within the enclave and reading a value from the enclave's default buffer into a variable accessible outside the enclave. In preparation for more operations supported by the enclave the names of the current enclave operations are changed to more accurately reflect the operations and more easily distinguish it from future operations: * The enums ENCL_OP_PUT and ENCL_OP_GET are renamed to ENCL_OP_PUT_TO_BUFFER and ENCL_OP_GET_FROM_BUFFER respectively. * The structs encl_op_put and encl_op_get are renamed to encl_op_put_to_buf and encl_op_get_from_buf respectively. * The enclave functions do_encl_op_put and do_encl_op_get are renamed to do_encl_op_put_to_buf and do_encl_op_get_from_buf respectively. No functional changes.
