A new method is needed that returns the length of the last certification
path validated by sun.security.validator.PKIXValidator. It is necessary
since engineValidate() may modify the length of the path before invoking
java.security.cert.CertPathValidator.validate() and there may be
PKIXCertPathCheckers that depend on the length of the path to perform
their processing (ex: a checker that checks for an extension in intermediate
CA certs needs to maintain a counter so it knows when it is passed the target
certificate).
