 * CERT_PKIXVerifyCert
 *
 * Verify a Certificate using the PKIX library.
 *
 * Parameters:
 *  cert    - the target certificate to verify. Must be non-null
 *  params  - an array of type/value parameters which can be
 *            used to modify the behavior of the validation
 *            algorithm, or supply additional constraints.
 *
 *  outputTrustAnchor - the trust anchor which the certificate
 *                      chains to. The caller is responsible
 *                      for freeing this.
 *
 * Example Usage:
 *    CERTValParam args[3];
 *    args[0].type = cvpt_policyOID;
 *    args[0].value.si = oid;
 *    args[1].type = revCheckRequired;
 *    args[1].value.b = PR_TRUE;
 *    args[2].type = cvpt_end;
