22c91df2ec Add support for global touchpad swipe gestures
Summary:
This change adds global touchpad swipe gestures to the
GlobalShortcutsManager and hooks up the swipe gestures as defined at the
Plasma Affenfels sprint:
 * swipe up: Desktop Grid
 * swipe down: Present Windows
 * swipe left: previous virtual desktop
 * swipe right: next virtual desktop

The main work is handled by two new classes: SwipeGesture and
GestureRecognizer. This is implemented in a way that it can be extended
to also recognize touch screen gestures and pinch gestures.

The SwipeGesture defines what is required for the gesture to trigger.
Currently this includes the minimum and maximum number of fingers
participating in the gesture and the direction. The gesture gets
registered in the GestureRecognizer.

The events for the gesture are fed into the GestureRecognizer. It
evaluates which gestures could trigger and tracks them for every update
of the gesture. In the process of the gesture tracking the
GestureRecognizer emits signals on the Gesture:
 * started: when the Gesture gets considered for a sequence
 * cancelled: the Gesture no longer matches the sequence
 * triggered: the sequence ended and the Gesture still matches

The remaining changes are related to hook up the existing shortcut
framework with the new touchpad gestures. The GlobalShortcutManager
gained support for it, InputRedirection and EffectsHandler offer methods
to register a QAction. VirtualDesktopManager, PresentWindows and
DesktopGrid are adjusted to support the gesture.

32f4e115e2 Drop KWin's internal global shortcut handling
Summary:
During the Wayland porting a KWin internal global shortcut handling got
implemented prior to the porting of KGlobalAccel. This allowed to trigger
global shortcuts with a KGlobalAccel still on X11 and unknown to KWin.

Nowadays KWin directly provides KGlobalAccel, thus it's no longer
required. The code was runtime dead as we always have a KGlobalAccel.

7dfe408506 Pass Qt::Key to GlobalShortcutsManager::processKey
So far this method translated the keysym to Qt::Key. This is no longer
needed as the only method which invokes processKey has access to the
translated key. Thus saving one translation for every key press.

4235871667 Remove not-wanted modifiers prior to evaluating global shortcuts
Summary:
When triggering global shortcuts we are more interested in the hold
keys than the currently active modifiers. E.g. capslock should not
be seen as "shift is hold". Similar we need to remove consumed
modifiers. Shift+5 is % and not Shift+% - the shift modifier is
consumed and needs to be removed from shortcut evaluation.

To support this we need to have the actual state directly from
xkbcommon. Thus a new method is added which exposes the modifiers
relevant for global shortcut matching. In addition on every key press
all consumed modifiers are calculated and kept so that they can be
used for shortcut matching.

In addition a workaround is added for Backtab. Similar workaround
exists in kglobalaccel for X11. The problem is that our shortcuts are
stored incorrectly: Shift+Tab instead of Backtab. Thus a mapping back
is required. To make everything worse KWin registers the wrong key
sequence "Alt+Shift+Backtab" which doesn't make any sense and is
broken on X11 at least.

The workaround supports both special cases. The one for Backtab should
be turned into Shift+Tab and also KWin's special case of adding shift
to backtab.

316914a38b Change supported platforms of kglobalaccel plugin to "org.kde.kwin"
Overwrite the platform name through the environment variable and ensure
that the plugin is not picked in non-kwin Wayland sessions as that puts
kglobalaccel5 into a crash restart loop.

3041a7c32d [wayland] Add a plugin for kglobalaccel
The KGlobalAccelD which gets created by KWin needs a plugin for the
platform specific parts. This change introduces such a plugin. It's
linked against kwin so that it can integrate with the core.

On enable the plugin registers itself in the InputRedirection and
GlobalShortcutsManager checks the plugin whether a shortcut got
triggered.

As the loading of the plugin must happen after InputRedirection is
fully created a dedicated init method is added to InputRedirection.

org.kde.kglobalaccel to prevent kglobalaccel5 from starting.

24b23dfc01 Beginning of global shortcut handling inside KWin
A new GlobalShortcutsManager is introduced which is responsible for
holding the registered shortcuts and triggering the matching action.

The InputRedirection checks with the GlobalShortcutManager whether a key
press event triggers a global shortcut and stops processing the event in
that case.

At the moment the GlobalShortcutsManager only supports the very basics
for KWin internal usage. External applications can not yet make usage of
the global shortcut system inside KWin.
