Some ASN.1 OID-identified algorithms require additional parameters, such as an initialisation vector for a block cipher. The structure of the parameters is defined by the individual algorithm. Extend asn1_algorithm() to allow these additional parameters to be returned via a separate ASN.1 cursor. Signed-off-by: Michael Brown <mcb30@ipxe.org>
