This requires mostly making moc a bit more permissive, which has the
advantage that it also simplifies the code a little bit.
The newly added test case demonstrates how to connect such a property
with a change signal.
One test case needed to be changed regarding the callback as the
publicProperty member now has a (permanent) observer and therefore
re-assigning the binding will re-evaluate it as the value might have
changed.

When a class has multiple QProperty members to implement functionality,
it is common to have functions in the class that react to changes. For
example to emit a compatibility signal, in case of Qt Quick to mark the
scene graph as dirty, etc. etc.
To faciliate this use-case, this patch adds an internal
QPropertyMemberChangeHandler template that allows connecting a QProperty
field to a member function callback.
At the moment that callback is still 3 * sizeof(pointer). This could in
theory be reduced to 2 by eliminating the back-pointer (prev) as the
observer lives as long as the property. That however belongs into maybe
a future patch.
In order to get a pointer back to the surrounding object that holds the
QProperty as well as provides the callback function, the property system
was changed to pass through the address of the QProperty member at
run-time, and at compile time the delta from the QProperty member to the
beginning of the surrounding class is calculated. Through subtraction we
obtain the pointer to the owning object.

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.

(This reintroduces c17a5cec19,
which was reverted in Qt 5 because it requires API level 23.)
This flag tells the app to use as much of the screen as possible
while still keeping system UI visible, and can be supported on Android
by using translucent system UI, similar to iOS.
What this does:
1. It changes the current fullscreen/not-fullscreen logic to
allow three states: fullscreen, fullscreen with translucent
decorations and not-fullscreen.
2. In order for it to work, we have to send the actual
screen geometry and available geometry, at least in the case
where the user needs to know the available geometry to
know the safe area of the window. So we get the real screen
metrics and pass these to the QPA plugin (API level 17, so
we can do that now that the minimum version is 21.)
3. Note that getting the insets and calculating the useable
area does not work for non-fullscreen windows, since Android
is quite inconsistent in this respect. So in this case we
just use the window size and origin of 0,0 for the available
geometry.
4. Since we are touching this code anyway, this patch also tries to use
more consistent wording (calling it "available geometry" everywhere
instead of desktop geometry in some places and just geometry in
others, etc.)

flag is now supported, and will make the window fullscreen, but keep

Duplicating the number of classes is a high price to pay to be able to
have some QAction functionality behave differently, or be only available
in widgets applications.
Instead, declare the entire API in QtGui in QAction* classes, and
delegate the implementation of QtWidgets specific functionality to
the private. The creation of the private is then delegated to the
Q(Gui)ApplicationPrivate instance through a virtual factory function.
Change some public APIs that are primarily useful for specialized tools
such as Designer to operate on QObject* rather than QWidget*. APIs that
depend on QtWidgets types have been turned into inline template
functions, so that they are instantiated only at the caller side, where
we can expect the respective types to be fully defined. This way, we
only need to forward declare a few classes in the header, and don't
need to generate any additional code for e.g. language bindings.
