Whitelist some System.Buffer methods * System.Buffer.BlockCopy( System.Array, System.Int32, System.Array, System.Int32, System.Int32 ) * System.Buffer.ByteLength( System.Array ) * System.Buffer.GetByte( System.Array, System.Int32 ) * System.Buffer.SetByte( System.Array, System.Int32, System.Byte ) interopgen: don't needlessly overwrite subfiles as this would cause c++ rebuilds everytime
