Clean-up the duplicate code in QFuture and QFutureWatcher
QFuture<void> and QFutureWatcher<void> are specialized to not contain
any of result fetching methods, but otherwise they share almost the same
implementation with QFuture<T> and QFutureWatcher<T> respectively.
This change unifies their implementations to get rid of unnecessary code
duplication.
