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.

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.

Summary:
* KWin has a Libinput version requirement bump to 1.5
* new isTouchpad property to distinguish touchpads from mice
* new lmrTapButtonMap property
* new disableWhileTyping property
* new pointerAccelerationProfile property
* new defaultPointerAcceleration property
* save to config mechanism added for new propertys and pointerAcceleration
* new D-Bus interface org.kde.KWin.InputDeviceManager and method devicesSysNames

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.

Some small improvements / fixes to the libinput backend:
- Query libinput_device_config_left_handed_get_default
- 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.

The autotests are failing on build.kde.org due to the generated DBus
object path not being valid. This might be due to sysName having been
empty by default.
Summary:
The Connection exposes a new service called org.kde.KWin.InputDevice
and every Device registers an own object exposing all properties.
This allows an external configuration tool to change the behavior of
the devices at runtime. E.g. to test configuration settings.

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.
This test mocks part of KWin::Udev, udev and libinput. The test itself
is still rather limited and only verifies whether libinput is valid or
not and that assignSeat works. Most of the interaction is not yet tested,
though to a large degree doesn't make sense and should be rather tested
in the context of LibInput::Connection.
This new test includes everything used in events.cpp to the mocked
functionality of libinput. Only key event is implemented so far, the
referenced pointer and touch functions are mocked with default values.
The test verifies that a KeyEvent gets created and the key press/release
works as expected.
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.

This reverts commit abe582c27d.
To explain: the test uses a mocked implementation of libinput. Because
of that it must not link against libinput. The whole idea is to not link
libinput.
So I'm reverting the addition of libinput to linkage. I don't know the
build error, if it gets presented to me, I'll fix it properly without
having to add a linkage to libinput.
Summary:
Device has a static QVector<Device*> into which each created Device
is added and provides a static method to match a libinput_device* to
the already created Device.
This can be used by the the libinput Event class wrapper to properly
reference the Device the event is for.

Summary:
The usage of libinput is completely mocked. The test covers all the
constant properties read by Device.
There are some features which are not yet tested:
* alphaNumericKeyboard
* supportedButtons
* enabled
The setters for leftHanded and pointerAcceleration are also covered
including the variants where it can fail.
