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

Background:
It is often necessary/advisable to schedule tasks on thread pools !=
globalInstance(). As Herb Sutter writes in
http://www.drdobbs.com/parallel/use-thread-pools-correctly-keep-tasks-sh/216500409
and the Qt Training Material stresses, tasks you schedule on a (global)
thread pool should be non-blocking, which currently rules out using any of
the QtConcurrent functions for, say, file I/O.
Nonetheless it's often convenient to have thread pools also for file I/O, as
the thumbnail viewer exercise in the Qt Training Material shows. In this
case, you'd use a dedicated thead pool, leaving the global thread pool for
CPU-bound tasks.
Yet, none of the QtConcurrent functions allow to pick the QThreadPool
instance on which to schedule the work created with them.
This patch prepares for them to do so.
This is the first part of the forward-port of
https://qt.gitorious.org/qt/qt/merge_requests/1281.
Implement by using a new QThreadPool* member that defaults to nullptr,
and adding setThreadPool to set this member, then using it in lieu of
QThreadPool::globalInstance() everywhere.
I chose to leave m_pool == nullptr to mean globalInstance() to avoid
creating the global instance whenever a QFuture is created, even if the
future represents the result of a calculation not run on the global thread
pool.
[ChangeLog][QtCore][QFuture] Can now be used with any QThreadPool, not
just globalInstance().

This is extremely useful, since the most common action after a failed
compare-and-swap is to loop around, trying again with the current
value as found in memory.
Code currently written as:
do {
Type value = atomic.load();
...
} while (!atomic.testAndSetRelaxed(value, desired));
Becomes:
Type value = atomic.load();
do {
...
} while (!atomic.testAndSetRelaxed(value, desired, value));
In most CPU architectures, the value that was found in memory is known
to the compare-and-swap code, so this is more efficient than the
previous code. In architectures where the value is not known, the new
code is no worse than before.
The implementation sometimes modified an existing function, sometimes
it added a new one, depending on whether more registers were needed in
the assembly (like ARMv6-7), the code became more complex (ARMv5), the
optimizer failed (C++11), or it was just plain equivalent (MIPS).

The current synchronization mechanism was racy: decrementing waitingThreads
and then hoping that the wakeOne will wake a thread before its expiry
timeout happens. In other words, on timeout, a just-assigned task would
never run. And then no other task would run, if maxThreadCount is reached.
Fixed by using a queue of waiting threads (rather than just a count), and by
moving the wait condition into the thread itself, so we know precisely
which one we're waking up, and we can remove it from the set of waiting threads
before waking it up, and therefore it can determine on wakeup whether it
has work to do (caller removed it from the queue) or it expired (it's still
in the queue). This is reliable, whereas the return value from QWaitCondition::wait
isn't reliable, when the main thread has already decided that this thread
has work to do.

The code uses a QSignalSpy to check whether the thread started,
but the signal emission (and subsequent appending to the spy) and
the check for spy.count() before the final thr.wait() are not
synchronized:
The signal emission happens-after the thr.start() and -before the
final thr.wait(). Likewise, the spy.count() happens-after thr.start()
and -before thr.wait(), but neither one happens-before the other.
Thus, there is a data race.
The wait(200) between thr.start() and mutex.unlock() doesn't help,
either, because we check only that it doesn't return true, iow, we
check that it timed out. But it will happily do that if the thread
has not yet started executing, so there's no happens-before relation
to be had via that avenue, either.
I first fixed by moving the spy.count() check to after thr.wait().
In that case:
signal emission happens-before thread finishing
happens-before thr.wait() returning
happens-before spy.count()
so no race.
Arguably, that makes the check rather useless, so I decided to remove
it completely.

QTBUG-21051 has a testcase where activeThreadCount() could actually
end up at -1 (converted to an autotest in this commit).
The reason was: start() calls tryStart() which returns false due to
too many active threads (reserveThread() causes this), so it calls
enqueueTask() - which actually wakes up the waiting thread, but
it didn't decrement the number of waiting threads.
Note that tryStart() is "if I can grab a waiting thread, enqueue task and wake it"
while start(), in case tryStart() fails, wants to "enqueue, and then if I can grab
a waiting thread, wake it". This is why enqueue shouldn't wake; waking must happen
only if we can grab a thread (d->waitingThreads > 0).
