/**
* 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>>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).
* @throws IOException if certificate does not get closer
