The function, pkcs7_verify_one(), will be utilized to rework signature verification logic aiming to support intermediate certificates in "chain of trust." To do that, its function interface is expanded, adding an extra argument which is expected to return the last certificate in trusted chain. Then, this last one must further be verified with signature database, db and/or dbx. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org>
