68c675d00d Make source code more relocatable
Occasionally, I see complaints about the file organization of kwin,
which is fair enough.

This change makes the source code more relocatable by removing relative
paths from includes.

CMAKE_CURRENT_SOURCE_DIR was added to the interface include directories
of kwin library. This means that as long as you link against kwin target,
the real location of the source code of the library doesn't matter.

With autotests, things are not as convenient as with kwin target. Some
tests use cpp files from kwin core. If we move all source code in a src/
directory, they will need to be adjusted, but mostly only in build
scripts.

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.

aa6c8f8116 Add support for activating screenedges through touch swipe gestures
Summary:
Each Edge creates a SwipeGesture for touch activation. The swipe needs to
be a single finger starting from the edge into the screen for at least
20 %. The SwipeGesture and GestureRecognizer is extended to support the
use cases of the touch screen edge swipe.

New features supported by the gesture system are:
 * minimum and maximum position
 * a minimum delta for the swipe
 * progress signal based on the minimum delta
 * starting a swipe with a start point

The Edge has the progress signal connected to its approach signal, thus
visual feedback is provided through the screen edge effect.

The screen edge system supports touch only for the edges (corners are
too difficult to activate on touch screens). At the moment the following
features are supported:
 * screen edge show/raise of windows (e.g. auto hidden panels)
 * trigger the configured action
 * trigger the configured callback function (e.g. script)

In future it might make sense to add a touch specific configuration
action to support different actions for screen edges activated by mouse
and touch.

BUG: 370323

Test Plan:
configured a screen edge and triggered through touch,
added an auto-hiding panel and triggered through touch

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.
