> PortableDataStream should be a factory

> Key: SPARK-11449

> {{PortableDataStream}}'s close behavior caught me by surprise the other day.
> I assumed incorrectly that closing the inputstream it provides would also
> close the {{PortableDataStream}}. This leads to quite a confusing situation
> in when you try to reuse the {{PortableDataStream}}: the state of the
> {{PortableDataStream}} indicates that it is open, whereas the underlying
> inputstream is actually closed.
> I'd like either to improve the documentation, or add an {{InputStream}}
> wrapper that closes the {{PortableDataStream}} when you close the
> {{InputStream}}. Any thoughts?
