/**
 * Determine how close a given certificate gets you toward
 * a given target.
 *
 * @param constraints Current NameConstraints; if null,
 *        then caller must verify NameConstraints
 *        independently, realizing that this certificate
 *        may not actually lead to the target at all.
 * @param cert Candidate certificate for chain
 * @param target GeneralNameInterface name of target
 * @return distance from this certificate to target:
 * <ul>
 * <li>-1 means certificate could be CA for target, but
 *     there are no NameConstraints limiting how close
 * <li> 0 means certificate subject or subjectAltName
 *      matches target
 * <li> 1 means certificate is permitted to be CA for
 *      target.
 * <li> 2 means certificate is permitted to be CA for
 *      parent of target.
 * <li>&gt;0 in general, means certificate is permitted
 *     to be a CA for this distance higher in the naming
 *     hierarchy than the target, plus 1.
 * </ul>
 * <p>Note that the subject and/or subjectAltName of the
 * candidate cert does not have to be an ancestor of the
 * target in order to be a CA that can issue a certificate to
 * the target. In these cases, the target distance is calculated
 * by inspecting the NameConstraints extension in the candidate
 * certificate. For example, suppose the target is an X.500 DN with
 * a value of "CN=mullan,OU=ireland,O=sun,C=us" and the
 * NameConstraints extension in the candidate certificate
 * includes a permitted component of "O=sun,C=us", which implies
 * that the candidate certificate is allowed to issue certs in
 * the "O=sun,C=us" namespace. The target distance is 3
 * ((distance of permitted NC from target) + 1).
 * The (+1) is added to distinguish the result from the case
 * which returns (0).
