I wish AlgorithmParameters was actually AlgorithmIdentifier which is OID+params, but it's too late. Sigh.

The existing spec was very strict in the way set and get parameters were handled.  This modifies that slightly by allowing null to be returned by the get methods when it is unsupported after the parameters have been set. Since null was an allowed return value, this minimizes the backwards compatibility chances.
