1fb9f6f13a Switch to SPDX license markers
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.

In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.

684b4b635e Use more traditional doxygen style
Summary:
So far we were following a bit unique and rare doxygen comment style:

    /**
     * Contents of the comment.
     **/

Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.

    /**
     * Contents of the comment.
     */

Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.

This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

8af2fa73dc Run clang-tidy with modernize-use-override check
Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.

The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.

Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.

A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!

The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.

The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.

Test Plan: Compiles.

7b20e1f66f Overhaul doxygen comments
Summary:
We have a mix of different doxygen comment styles, e.g.

    /*!
      Foo bar.
     */

    /**
     * Foo bar.
     */

    /** Foo bar.
     */

    /**
     * Foo bar.
     */

    /**
     * Foo bar.
     **/

To make the code more consistent, this change updates the style of all
doxygen comments to the last one.

Test Plan: Compiles.

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.

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.

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.
