Summary:
Prior to this change various event filters performed deep calls into
Xkb class to figure out the modifiers relevant for global shortcuts (aka
consumed modifiers). This shows that this is a general useful
information which should be available to all input event filters
directly.
Thus it's now added to the input events and exposed directly in
InputRedirection so that the calls into Xkb are no longer needed.

Summary:
The TabBox performs the scrolling of the items by itself in order to
support wheel events even if the mouse is not on the TabBox. For that
KWin grabs pointer events on X11 (on Wayland an input filter is used)
and forwards them to the TabBox.
Qt uses Xinput2 for scrolling on the QQuickWindow. Due to that KWin
does not get any xcb core button press/release events when scrolling
inside the QQuickWindow and thus scrolling doesn't work.
There are three possible approaches to fix this:
1. Implement scrolling support in each of the QML switchers
2. Add an xinput2 filter to TabBox
3. Intercept the QWheelEvents on the QQuickWindow
The first approach has the disadvantage that all themes need
adjustment and that there might be behaviorial difference whether one
scrolls on the TabBox window or outside the window.
The second approach would be most in line with the other filters, but
is difficult due to the nature of xinput2 (no xcb bindings, etc).
Thus the third approach might be the best solution. Wheel events are
only delivered to the QQuickWindow if the native events were not already
intercepted, thus we know it won't have side effects for the case that
Wayland is used or xinput2 is not supported.
The implementation installs an event filter on the QQuickWindow which
gets created when showing the TabBox and inside the filter waits till
there is an angleDelta of +/-120 and scrolls by one per every 120 angle
delta as described in the QWheelEvent documentation.

Summary:
The interaction is changed to trigger the check for release from the
TabBoxInputFilter instead of reacting on modifier changes. That way
it's possible to check for the relevant modifiers getting released
instead of getting all modifiers in. Also this means that the checks
are only performed when relevant.

Summary:
So far TabBox used highlight windows by passing window ids around through
an X property. This doesn't work on Wayland where we don't have window
ids for our TabBox and the Wayland windows.
This change introduces a new Effect::Feature for HighlightWindows which
the HighlightWindowsEffect provides. The EffectsHandlerImpl has a new
method to highlightWindows which it delegates to that effect if it is
loaded by invoking a new performFeature method.
The TabBoxHandler now passes the highlighting to the effects system
instead of updating the x11 property. Thus this works on Wayland and
at the same time improves the X11 side by no longer having to go through
the property protocol.
Test Plan: Verified that Alt+Tab highlights the windows on Wayland correctly.

Summary:
Toplevel::window() is the actual X11 window. This makes it difficult
to use as the generic identifier for both X11 and Wayland. The Wayland
ShellClient already had a windowId() which is now added to Toplevel as
a virtual method. On X11 (Toplevel default) it returns the window().
The method window() now returns XCB_WINDOW_NONE for classes without
the Toplevel::m_client, such as ShellClient. Thus it allows to properly
check whether we are on Wayland or X11.
The code is adjusted to use windowId where a generic id is needed and
to properly check whether the window is valid before using it where
a window() is used.
This also fixes at least one additional unknown issue in
Workspace::setActiveClient
where the windowId of a Wayland client was passed to X11.

The TabBox implements methods for those events and performs same
logic as on X11. Click outside of TabBox closes. If the event is on
the TabBox we don't filter the event out and let the internal filter
forward the event.
By using QWindow we can also find the TabBox window on Wayland where
the winId is not really helpful.
This also changes the elevation from Unamanged to Toplevel, so that
it is no longer X11 specific.
Result: TabBox stays on top of all windows also on Wayland.
-use qstringliteral only when necessary (i.e. not in concat or comparison)
-use qbytearray instead of qstring when dealing with latin1 input and output (glplatform)
-use qstringref to extract numbers from strings (glplatform)
-define qt_use_qstringbuilder to optimize all string concatenations
-anidata: use ctor init lists, add windowType member initialization

not everytime the current screen changes.
a) that pollutes the geometry when the tabbox is invoked
b) it's insufficient for "Active Screen follows mouse" (the default)
c) less overhead (ok: "on multiscreen")

This is a temporary workaround for bug 349992 which causes freezes
during startup as kwin and kamd dead lock each other on DBus.
To workaround we don't call Activities::create and check in every
usage of Activities::self() whether the pointer is valid.
As a result kwin_wayland now starts pretty fast.

The change is mostly straight forward. Effects are straight forward
adjusted. Client::findModal is moved up, this causes still a few
dynamic_casts to Client. Mostly because Workspace::activateClient still
operates on Client.
As external interface it still returns Client* to not force the casts
to be done at usages. This will be changed once the users are migrated
to AbstractClient*.
This is now crucial, because while before
(the minimized) windows were conditionally
shown, but are now always behind the desktop.
Also, it makes the tabbox more consistent.

KWin::connection() uses the property to resolve the value instead of
using QX11Info. In practice this doesn't change anything at the moment,
but allows kwin_wayland to provide an xcb connection without depending
on QX11Info.
As we cannot make xcb_connection_t* available as a metatype, the
property's type is set to void*.
KGlobalAccel sets the timestamp as a property and we need to set our
x11Time to it otherwise following keyboard grabs might fail.
Requires 61e2a156678eef033b2629f7c72530dc78d7c3ac in kglobalaccel.
when restacking for shaded windows and uncomposited tabboxes
the group check should not be applied since we know better

Only needed for ScopedCPointer which can be defined in both utils and
xcbutils.h.
Not having utils.h in xcbutils.h makes it easier to have unit tests use
xcbutils.h as it removes the dependencies.
The build option got introduced for Plasma Active back in a time
when we did not properly aim for convergence. In a Plasma 5 world
we want to have only one shell and one window manager which adjust
itself. This means we don't want a differently compiled kwin for
plasma active, but the same one. Thus the build option doesn't
make much sense any more. A KWin for touch interface needs to support
screenedges for the case that mouse is plugged in.

Like with WindowSwitcher the configured value might be for the
look and feel package and thus we should first try to locate it
from the look and feel package.
We assume the configured layout name is a look and feel package. Thus
the Switcher is located at contents/windowswitcher/WindowSwitcher.qml
of that package.

We need to send the event to a QQuickItem which accepts focus. Just
sending it to the Window or to the contentItem doesn't work as there is
no activeFocusItem (might be related to having the keyboard grabbed).
We try to send the event to all children of the Window's content item.
There should hopefully be one item which accepts the event and properly
reacts on cursor keys.

Both were only added for the use case of Plasma Active. In the next
iteration we won't need the embedded any more as Plasma is able to draw
thumbnails by itself. So there is neither need for the embedded
functionality nor for the D-Bus interface.
REVIEW: 118464
We don't have access to the margins specified in anchors resulting in
incorrect thumbnail position. To fix this we need to create a dummy item
which does the anchoring and the thumbnail needs to just be an
anchors.fill: parent.

Instead of passing the macro based Predicate to findUnmanaged it now
expects a function which can be passed to std::find_if.
Existing code like:
xcb_window_t window; // our test window
Unmanaged *u = findUnmanaged(WindowMatchPredicated(window));
becomes:
Unmanaged *u = findUnmanaged([window](const Unmanaged *u) {
return u->window() == window;
});
In addition an overload is added which takes the window id to cover
the common case to search for an Unmanaged by its ID. The above example
becomes:
Unmanaged *u = findUnmanaged(window);
The advantage is that it is way more flexible and has the logic what
to check for directly with the code and not hidden in the macro
definition.
Forward all key press events to the TabBox if it is currently grabbed and
connect the TabBox to the modifiers changed signal for checking if TabBox
should be ended.
