* 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;
