/**
 * KeyUsage extension plays a important rule during looking for the issuer
 * of a certificate or CRL. A certificate issuer should have the keyCertSign
 * bit set, and a CRL issuer should have the cRLSign bit set.
 *
 * Sometime, a delegated CRL issuer would also have the keyCertSign bit set,
 * as would be troublesome to find the proper CRL issuer during certificate
 * path build if the delegated CRL issuer is a self-issued certificate, for
 * it is hard to identify it from its issuer by the "issuer" field only.
 *
 * In the test case, the delegated CRL issuers have keyCertSign bit set, and
 * the CAs have the cRLSign bit set also. If we cannot identify the delegated
 * CRL issuer from its issuer, there is a potential loop to find the correct
 * CRL.
 *
 * And when revocation enabled, needs to check the status of the delegated
 * CRL issuers. If the delegated CRL issuer issues itself status, there is
 * a potential loop to verify the CRL and check the status of delegated CRL
 * issuer.
 *
 * The fix of 6852744 should addresses above issues.
