stream: filter out elements without demand
This will also mean that completion will not be blocked by elements that
will later be filtered out.

One particular use case of that would be a kind of partitioning use case,
where you put several streams behind a broadcast and each consumer will filter
out elements not handled there. In that case, the broadcast can get head-of-line
blocked when one of the consumers currently has no demand but also wouldn't
have to handle any elements because they would all be filtered out.
