Generator has problems with multiple "out" parameters

[maxkatz6]

Consider:

HRESULT SaveBookmarkToBytes(IAvnString*fileUri, IAvnString**err, IAvnString**ppv);

Somehow it generates:

public void SaveBookmarkToBytes(IAvnString fileUri, IAvnString err, IAvnString res)

and

__target.SaveBookmarkToBytes(global::MicroCom.Runtime.MicroComRuntime.CreateProxyOrNullFor<IAvnString>(fileUri, false), INVALID, INVALID);

I will take a look once I get to that.
