Replace the implementation of blockingMappedReduced():
after calling non-blocking version of mappedReduced() we are getting
the future object, so we may call in sequence result(), which
will block and return the result when the all tasks are done.
The same is done with blockigMapped(), which calls blockingMappedReduced()
with a custom reduce function.
Looks like with this pattern we can reuse the non-blocking version
for implementing blocking version of mapped / filtered methods.

Deprecated the pause-related APIs of QFuture* classes and
added alternatives having "suspend" in the name instead.
With 2f15927f01ceef0aca490746302a5ea57ea9441c new
isSuspended()/suspended() APIs have been added to QFuture* classes for
checking if pause/suspension is still in progress or it already took
effect. To keep the naming more consistent, renamed:
- setPaused() -> setSuspended()
- pause() -> suspend()
- togglePaused() -> toggleSuspended()
- QFutureWatcher::paused() -> QFutureWatcher::suspending()
Note that QFuture*::isPaused() now corresponds to (isSuspending() ||
isSuspended()).
[ChangeLog][Deprecation Notice] Deprecated pause-related APIs of
QFuture and QFutureWatcher. Added alternatives having "suspend" in
the name instead.

Because setting QFutureInterface to paused state does not mean that
the computations that are already in progress will stop immediately,
it may be useful to get notified when pause actually takes effect.
Introduced the QFutureWatcher::suspended() signal, to be emitted when
there are no more computations in progress, and no more result ready
or progress reporting signals will be emitted, i.e. when pause took
effect. Added {QFuture, QFutureWatcher}::isSuspended() methods for
checking if pause took effect.
QtConcurrent will now to send QFutureCallOutEvent::Suspended event
when the state is paused and there are no more active threads.
[ChangeLog][QtCore][QFutureWatcher] Added a new QFutureWatcher::suspended()
signal, to be emitted when pause took effect, meaning that there are no

The virtual inheritance causes the issue, when adding
new, non-default constructor to the base ThreadEngineBase
class. It looks like classes derived from it can't
use the non-default constructor, even when it's called
explicilty from the subclass. Instead, the default constructor of the
ThreadEngineBase class is always required during compilation
and called on runtime.
In addition, the only sensible use of the virtual inheritance
is the multiple inheritance, but apparently it looks like
there is no single class in Qt which would multi inherit from
the ThreadEngineBase class, so this change shouldn't have any bad
side effects. This justifies the current lack of info on why it
was introduced originally ages ago.

QFuture's original design pre-dates C++11 and its
introduction of move semantics. QFuture is documented
as requiring copy-constructible classes and uses copy
operations for results (which in Qt's universe in general
is relatively cheap, due to the use of COW/data sharing).
QFuture::result(), QFuture::results(), QFuture::resultAt()
return copies. Now that the year is 2020, it makes some
sense to add support for move semantics and, in particular,
move-only types, like std::unique_ptr (that cannot be
obtained from QFuture using result etc.). Taking a result
or results from a QFuture renders it invalid. This patch
adds QFuture<T>::takeResults(), takeResult() and isValid().
'Taking' functions are 'enabled_if' for non-void types only
to improve the compiler's diagnostic (which would otherwise
spit some semi-articulate diagnostic).
As a bonus a bug was found in the pre-existing code (after
initially copy and pasted into the new function) - the one
where we incorrectly report ready results in (rather obscure)
filter mode.

We can't use qt_scoped_lock/qt_unique_lock here, so port to
std::unique_lock and std::lock_guard for now.
This is in preparation of deprecating QMutexLocker in favor
of std::unique_lock and std::scoped_lock.
In QFutureInterface, change the return type of mutex() from
QMutex* to QMutex&, so we don't need to deref when passing
to std::lock_guard. We need to keep the old method around
for BC reasons, so the new one needs an artificial function
argument for disambiguation. This will vanish come Qt 6.

Some modules define their own manually-maintained lists, and we can rely
on the headers generated by each module to include in the pch as well
e.g. QtCore/QtCore.
There's also e.g. QtWidgetDepends for QtWidgets, but this only
works for modules, not for tools, examples or other applications.
For now we'll use the Qt<Module>/Qt<Module> headers for the
modules we depend on.
Building with PCH can be disabled with -DBUILD_WITH_PCH=NO, and it only
works for versions of CMake newer than 3.15.20190829.
