642b9fce81 QtConcurrent::run: support non default-constructible return types
The QtConcurrent::RunFunctionTask class keeps a variable to store the
result of QtConcurrent::run when it becomes available, so that it can be
reported afterwards. This requires the result type to be
default-constructible. However there's no need in storing the result, it
can be reported immediately after it becomes available.

ad2da2d27a Remove the qmake project files
Remove the qmake project files for most of Qt.

Leave the qmake project files for examples, because we still test those
in the CI to ensure qmake does not regress.

Also leave the qmake project files for utils and other minor parts that
lack CMake project files.

ff0ba7e2d7 Forbid implicit conversions between QFuture and other types
- Remove the casting operator of QFuture<T> to T. It calls
  QFuture::result(), which may lead to undefined behavior if the user
  has moved the results from QFuture via QFuture::takeResult() before
  trying to do the conversion.

- Disable implicit conversion of QFuture<T> to QFuture<void>, by making
  the constructor explicit. If the users really intend to do the
  conversion, they should do it explicitly.

[ChangeLog][Source-Incompatible Changes][QFuture] Implicit conversions
of QFuture<T> to T and to QFuture<void> have been disabled. Use
QFuture::result() or QFuture::takeResult() where you need to convert
QFuture<T> to T. Use the explicit QFuture<void>(const QFuture<T> &)
constructor to convert QFuture<T> to QFuture<void>.

cc0be95ac7 QtConcurrent: Provide a test for runWithPromise with handlers
Test runWithPromise with "then" and "onCanceled" handlers.
Test the case when QFuture::cancel() is being called when
the task's thread already started, so that a call to
QPromise::isCanceled() from inside the running thread
returns different values in the same task's run. This nicely
proves that communication between QFuture and QPromise
works between different threads.

4c793e6353 Store std::exception_ptr in QUnhandledException
For historical reasons Qt Concurrent reports QUnhandledException in
case if an exception that is not derived from QException is thrown
from a worker thread. Changing this behavior may not be a good idea,
since the existing user code may rely on it. Changed QUnhandledException
to wrap the std::exception_ptr to the actual exception, so that the
users can obtain the information about the thrown exception if needed.

[ChangeLog][QtCore][QUnhandledException] Improved QUnhandledException to
store the std::exception_ptr to the actual exception thrown from a
QtCocnurrent worker thread.

765f503b1e QtConcurrent: Introduce runWithPromise()
The differences to run() method:
1. The passed function should have additional
   argument QPromise<T> &, declared as a first argument.
2. The return value of the function must be void.
   Result reporting should be done through
   passed QPromise<T> &promise argument.
3. By default, runWithPromise() doesn't support functors
   with overloaded operator()().
   In case of overloaded functors the user
   needs to explicitly specify the result type
   as a template parameter passed to runWithPromise,
   like:

   struct Functor {
       void operator()(QPromise<int> &) { }
       void operator()(QPromise<double> &) { }
   };

   Functor f;

   runWithPromise<double>(f); // this will select the 2nd overload

34fe9232db Port from QAtomic::load() to loadRelaxed()
Semi-automated, just needed ~20 manual fixes:

$ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)load\(\)/$1loadRelaxed\(\)/g' -i \{\} +
$ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)store\(/$1storeRelaxed\(/g' -i \{\} +

It can be easily improved (e.g. for store check that there are no commas
after the opening parens). The most common offender is QLibrary::load,
and some code using std::atomic directly.
