Previously QFutureInterface::setProgressValue was silently ignoring
the progress range and allowed to set any progress value.
Also no checks were performed in QFutureInterface::setProgressRange,
which allowed the user to set minimum > maximum.
Add checking of the current progress range, when settings the
progress value.
Add checks for minimum and maximum values while setting the progress
range.
The implementation of the checks is mostly based on the logic
that is used in QProgressBar.
- If maximum is smaller than minimum, minimum becomes the only legal
value.
- If the current progress value falls outside the new range, the
progress value is set to be minimum.
- If both progressMinimum() and progressMaximum() return 0, the
current progress range is considered to be unused, and any progress
value can be set.
- When setting the value using setProgressValue(), if the value falls
out of the progress range, the method has no effect.

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.

Added QFuture::then() methods to allow chaining multiple asynchronous
computations.
Continuations can use the following execution policies:
* QtFuture::Launch::Sync - the continuation will be launched in the same
thread in which the parent has been executing.
* QtFuture::Launch::Async - the continuation will be launched in a new
thread.
* QtFuture::Launch::Inherit - the continuation will inherit the launch
policy of the parent, or its thread pool (if it was using a custom one).
* Additionally then() also accepts a custom QThreadPool* instance.
Note, that if the parent future gets canceled, its continuation(s) will
be also canceled.
If the parent throws an exception, it will be propagated to the
continuation's future, unless it is caught inside the continuation
(if it has a QFuture arg).
Some example usages:
QFuture<int> future = ...;
future.then([](int res1){ ... }).then([](int res2){ ... })...
QFuture<int> future = ...;
future.then([](QFuture<int> fut1){ /* do something with fut1 */ })...
In the examples above all continuations will run in the same thread as
future.
QFuture<int> future = ...;
future.then(QtFuture::Launch::Async, [](int res1){ ... })
.then([](int res2){ ... })..
In this example the continuations will run in a new thread (but on the
same one).
QThreadPool pool;
QFuture<int> future = ...;
future.then(&pool, [](int res1){ ... })
.then([](int res2){ ... })..
In this example the continuations will run in the given thread pool.
