Manipulating a simple int from multiple threads is a data race,
thus undefined behavior.
Fix by using QAtomicInt and atomic operations instead.

When one of the QCOMPAREs in Consumer::run() fails, the consumer
returns early, leaving the producer deadlocked in a QSemaphore's
acquire() call. Change these to tryAcquire() with a large timeout,
so the producer, too, eventually leaves run().

By templating on the <chrono> types and unconditionally using
duration_cast to coerce the duration into a milliseconds, we
allowed code such as
mutex.try_lock_for(10us)
to compile, which is misleading, since it's actually a zero-
timeout try_lock().
Feedback from the std-discussions mailing list is that the
wait_for functions should wait for _at least_ the duration
given, because that is the natural direction of variance
(tasks becoming ready to run might not get a CPU immediately,
causing delays), while an interface that documents to wait
_no more_ than the given duration is promising something it
cannot fulfill.
Fix by converting the given duration to the smallest number
of milliseconds not less than the original duration. If that
is not representable in an int, use INT_MAX, emulating the
effect of a spurious wakeup, which are allowed to happen if
the function returns false in that case.
In the above example, the try_lock_for call is now equivalent
to
mutex.tryLock(1);
The tryLock() docs state that the actual waiting time does
not exceed the given milliseconds, but fixing that is a
separate issue.

This requires fixing the test on Windows: QMutex internally uses
WaitForSingleObjectEx which can wake up early, according to the system
timer resolution:
https://msdn.microsoft.com/en-us/library/windows/desktop/ms687069(v=vs.85).aspx#waitfunctionsandtime-outintervals
QTime must be so slow that it hides the early wakes, but QElapsedTimer is
accurate enough to make the test fail unless we add back some tolerance to
compensate for the early wakeups.

If the future is finished when a watcher starts watching it, it is
perfectly reasonable for the watcher to get the finished message
promptly. If you pause the watcher before any message loops get to
run, the message presently won't get through until the watcher is
resumed, but there is no reason to guarantee that; indeed, one could
consider it somewhat perverse behavior.
So move the reportFinished() calls to after the pause()s.
Also eliminate a used-once local variable and use QTRY_VERIFY() in one
place where qWait() was used before.
