Summary:
Libinput returns -1 when calling libinput_event_touch_get_slot on an event
from a single-touch touchscreen. The returned value is used in
DecorationEventFilter to determine the touch which is acting on it. The value -1
is used to signify that the decoration is not being acted on. Thus when
releasing the touch, it checks whether it was being dragged, and as it thinks
it isn't, it doesn't handle it and the decoration is still being dragged.
Clicking on the decoration then crashes kwin.
Test Plan: Move a window by dragging the decoration with a single-touch touchscreen.

Summary:
Making QActions with the Connection as a parent is dangerous as it gets
moved to a new thread, moving all child objects to that thread.
KGlobalAccel and QAction aren't thread safe and we shouldn't be using it
in two threads. This was notably seen when runnng invokeShortcut over
DBus which then invokes it on the main thread. Something my laptop was
doing when I closed the lid.
This patch simply moves the code to the Input class, where we set up the
libinput connection.
Test Plan:
Closed lid, kwin_wayland was still there when I resumed
Set manual shortcut for toggling touchpad, that still worked

Go for a more intuitive unset behaviour of scroll method and acceleration
profile properties.
Summary:
Unsetting a scroll method should only work, if the scroll method is currently
active. For example when scroll-two-finger is active (i.e. scroll-edge,
scroll-on-button-down is not active):
* unsetting scroll-two-finger should deactivate it and activate no-scroll
* but unsetting for example scroll-edge should _not_ deactivate scroll-two-
finger and _not_ activate no-scroll
Reworked setting scroll method auto test in order to test it.
Regarding acceleration profiles: Unsetting one, should always switch to the
other possible one as long as both are supported. In this case
LIBINPUT_CONFIG_ACCEL_PROFILE_NONE is not a valid option in contrast to the
definition of the scroll method enums.

This is a larger patch rewriting some parts of the config saving functionality
in device.cpp in order to:
1. Make it possible to save ScrollMode as integer instead of using three booleans
2. Simplify the addition of new keys or types in the future
Changes in detail:
a) Adds new ConfigKey ScrollMethod and removed now unnecessary keys per method
b) Adds constructors to the ConfigData struct. This allows to create ConfigData
entries for s_configData without the need of stating empty brackets and the
useage of default values.
c) Use plain member function pointers instead of std::function, in order to
compactify code and have better compile output in case something goes wrong.
c) Cleans up ScrollMethod functions and adds interface methods for transforming
the saved integer into type enum libinput_config_scroll_method.
d) Adjusts auto test for loading the ScrollMethod value from the config file.

- Write leftHanded property to config file
- When saving the touchpad scroll mode, write false to all other ones.
Otherwise it will always enable the last read entry after reboot.
- Use macro for setLeftHanded(bool) and setNaturalScroll(bool)

Summary:
Device gets a KConfigGroup injected and supports loading device-specific
settings. This is invoked from Libinput::Connection when adding a new
Device.
Whenever a Device option is changed successfully through the DBus
interface it gets synced into the KConfigGroup, thus on next loading of
the Device it gets restored.
The config group follows a pattern of:
[libinput][vendor][product][name]
Thus every device has a specific and persistent configuration.
Test Plan: So far only tested through autotests

Summary:
If KWin interacts with Libinput the RelativePointerManager interface
gets created on the Wayland server. The ForwardInputEventFilter does
forward the relative motion events in addition to the normal motion
events.
In order to properly support the relative motion events as they are
expected by the Wayland protocol the handling of pointer motion events
got slightly adjusted:
* Libinput Pointer event extended by the additional data points
* Libinput Pointer event carries the delta as a QSizeF instead of
QPointF
* PointerInputRedirection adjusted to take a pointer motion event with
more arguments
* Custom QMouseEvent subclass adjusted to carry the additional members
The DebugConsole is adjusted to show the relative motion events in
addition to the global position.
Test Plan:
Verified the manager object is created and verified the
events in DebugConsole. Unfortunately not aware of any test application.

From libinput documentation:
Also optional is a feature called "drag lock". With drag lock disabled,
lifting the finger will stop any drag process. When enabled, libinput
will ignore a finger up event during a drag process, provided the finger
is set down again within a implementation-specific timeout.
From libinput documentation:
A tap immediately followed by a finger down and that finger being held
down emulates a button press. Moving the finger around can thus drag
the selected item on the screen.
Summary:
Gesture events are swipe or pinch events on a touch pad.
This change implements basic support by:
* wrapping them in LibInput::Event
* processing them in LibInput::Connection and emitting
dedicated signals
* Forwarding them in InputRedirection to PointerInputRedirection
* Support them in the internal input event filter
* Printing debug information in DebugConsole
Further handling is not yet done. In future the following should be
implemented:
* activating e.g. zoom and present windows on pinch/swipe gesture
* forwarding non global gestures to KWayland
Note that forwarding to KWayland is not yet useful as QtWayland does
not yet have support for the unstable protocol. No Qt application could
make use of it yet. So for the moment just global gestures is the best
we can get.
Test Plan: Looked at output of DebugConsole when triggering gestures

The capability tablet tool is new in Libinput 1.2. As build.kde.org
does not yet support this version, it's only an optional check.
So far the code only detects whether the capability exists and reports
this accordingly.
Summary:
Device is created from Connection::processEvents which is run in the
main gui thread, while Connection itself is in a different thread. Thus
passing *this* as parent is wrong.
This change removes the parent, moves the created Device into the
Connection thread and also deletes properly by using deleteLater.

Summary:
The signals emitted by LibInput::Connection carry the Device for which
the input event was received. This Device is passed to the input handlers.
Custom event classes are added which extend QMouseEvent, QKeyEvent and
QWheelEvent respectively and expose the Device. The Device is only passed
around as a forward declared pointer, so even if compiled without libinput
support, it should still compile.
Event handlers which need to get access to the Device can now just cast
the event pointer to the custom class and access it. This can be used in
future to handle device specific key codes, etc.
As we don't have a proper event classes for touch events the event
handlers do not yet have access to the Device. Here the internal API
needs to be adjusted in future.

Summary:
The LibInput::Device provides a way to enable/disable the device.
This is used by the Connection to toggle all touchpad devices on/off
when the touchpad key is pressed. For this KWin "steals" the global
shortcuts from the touchpad kded.
Detecting what is a touchpad is unfortunately not tivial. The code
uses the following approach:
* it's a pointer
* it's not also a keyboard or touch screen
* it's at least one of the following:
** supports multiple tap fingers
** supports disable while typing
** supports disable on external mouse
If the code finds a touchpad and changes it's state successfully,
it triggers the touchpadEnabledChanged on Plasma's osdService.
Test Plan: Tested on notebook with toggle touchpad button

Summary:
The configuration file kcminput, group Mouse is parsed to decide whether
pointer devices should be in left handed mode. The config is applied
whenever a new device is added.
In addition the Connection listens to KGlobalSettings for a mouse
settings changed signal which might be emitted by the mouse KCM.
When such a signal is emitted, all pointer devices are reconfigured.
This allows to change the mouse handed settings on Wayland.

Apparently libinput is too old and LIBINPUT_DEVICE_CAP_TABLET_TOOL is
not yet available. As we don't use it yet, it's put into the #if 0 part
for future use.
Summary:
The Device class wraps all the information we can get from libinput
about the device, like whether it's a keyboard, pointer, touch, etc.
In addition some more information is queried to figure out how "useful"
a device is. For a keyboard all alphanumeric keys are checked whether
they exist, for a pointer all (normal) buttons are queried.
All the information is exposed as Q_PROPERTY and used by the
DebugConsole. The DebugConsole gained a new tab "Input Devices" which
renders all devices and their properties in a tree view. When plugging
in/out a device, the model gets reset, so it's always up to date.
The new Device class can be used in future to configure the device,
e.g. disable touch pad, set mouse acceleration, etc.

Let's get all debug events from libinput and forward them to a custom
log handler. This in turn can pass them to Qt's categorized logging.
So it's still easy to
* disable all libinput related logging
* configure the log level
Both was not possible before.
The Connection thread fills the event queue, it gets read from the
main thread. In order to properly support the threaded approach the
setup is changed to delegate into the own thread.
When the Connection is created we move it into a dedicated thread
so that even processing happens in the thread. Currently all events
are still queued directly.
