Eliminate pull mode traversal of streams.
All wrapIterator methods are gone.
Short-circuit terminal ops (and iterator()) now work by wrapping an iterator
around the (source iterator, sink chain) with a buffer at the end to catch
results, and dispensing those from iterator.
Short-circuit intermediate ops (such as limit) work by adding a
feedback channel in Sink.
