Most uses of the iterator are like this:
it, _ := rlp.NewListIterator(data)
for it.Next() {
do(it.Value())
}
This doesn't require the iterator to be a pointer and it's better to
have it stack-allocated. AFAIK the compiler cannot prove it is OK to
stack-allocate when it is returned as a pointer because the methods of
`Iterator` use pointer receiver and also mutate the object.
The iterator type was not exported until very recently, so I think it is
still OK to change this API.
