CloseableStream exceptions [was: Re: experience trying out lambda-8-b74]

[Olexandr Demura]

Isn't ConsumerEx imply existence of StreamEx &Co. so we do not need any
wraps?
where `StreamEx<T, Ex>` extends `BaseStream<T>`
and `ConsumerEx<T, Ex> { void accept(T o) throws Ex }` is not related to
`Consumer<T>`,
just like with primitives - other essential and dominant java feature.

Then void `close() throws Exception` is natural, leading to `Closeable`
`StreamEx`.
