Update auctions in place

Previously, ZQuery provided no way to update items in place when a stream was restarted. Instead, when a stream was restarted, ZQuery would set the state to undefined, then start processing streaming responses again.

With this PR's change, we can now handle streams a bit more intelligently. ZQuery no longer sets the state to undefined when restarting a stream; instead, it calls a new onStart() reducer (if it's passed to createZQuery()). Similarly, when a stream ends, errors, or is aborted, it calls handlers for those. It also calls an onValue() reducer when a value is received from the stream.

All those reducers are now returned by a stream function that consumers pass to createZQuery(), which allows consumers to maintain a JavaScript scope over the life of a stream. This allows you to update streamed items in place, and — in combination with onEnd() — discard any items from a previous stream that aren't present in the current stream. (See the implementation and docs for more detail.)
