Changing the shape of rust Future & Stream

On the tokio chat, @carllerche suggested that one way to simplify the "errors on streams" problem (rust-lang/futures-rs#206) would be to remove the error alternative from Future & Stream. This idea stuck with me, and I want to sketch out a possible alternative, to see how it would look.

Currently

• Future<Item, Error>: A future resolves to either an item or an error type, exactly like an async version of Result.
  • poll() -> Poll<Item, Error>: not ready, or an item, or an error
• Stream<Item, Error>: A stream emits elements that are each either an item or error, exactly like an async iterable of Result.
  • poll() -> Poll<Option<Item>, Error>: not ready, or the end of the stream (Ready(None)), or an item, or an error
