Pass error in stream.destroy()

Why stream.destroy is not call with err argument ?

In my stream object it will be nice to get the error.

```
class AskReply extends Transform {
destroy(error) { //error is always undefined
return super.destroy(error);
}
}
```

Start by reading the stream.destroy() handling in pump and the Transform subclass example, then trace how the error reaches super.destroy(error). Done means the originating stream error is available as the destroy() argument for the other stream, with behavior covered by an appropriate regression test.
