07c6878ff0 Introduce a KWin internal on-screen-notification service
Summary:
Recently we noticed that there are multiple areas where KWin needs to
inform the user about how to operate. Examples are:
* Screenshot
* ColorPicker
* Pointer constraint enabled
* Pointer constraint about to be removed
* Kill Window

For Screenshot and ColorPicker we used an EffectFrame to render it. But
this is not an optimal solution as it's lacking many features we would
need. We cannot properly use it from within KWin core, we cannot
implement features like hide on mouse over, etc. etc.

This change introduces an OnScreenNotification which supports:
* showing an icon
* showing a message
* timeout

It is Qml styled, so that it can be easily adjusted. This is a big
improvement over the EffectFrame solution. The Qml file creates a Plasma
Dialog of type OSD. Thus KWin places it like the normal OSD windows and
also looks kind of similar. In the case of KWin the focus is more on the
message, than an icon, so the icon is placed left of the text.

While the OnScreenNotification is supposed to be used like a singleton,
it doesn't use the KWin singleton pattern. Instead a small wrapper
namespace OSD is introduced which provides a convenient API for KWin
internal areas to show/hide the notification. By not using the KWin
singleton pattern, the OnScreenNotification does not depend on any other
parts of KWin and can be easily unit-tested.

A few features are still missing and will be added in further commits:
* hide-out on mouse over
* optional skip close animation (needed for screenshot)
* X11 support (not that important as it's mostly for Wayland features)

6383f83047 Place OSD windows again on size changes
Summary:
The position of an OSD is based on the size of the window. If the
size of the OSD changed, it would not be positioned correctly any more.

With this change the OSD window gets placed again if the size changes.
Thus it's also placed correctly even if the window changed it's size.

a7f5c16754 Reduce code-duplication of socketpair in WaylandServer
Summary:
WaylandServer creates a socketpair for several Wayland connections. So
far this duplicated code quite a bit.

This change introduces one method to perform the socketpair and the

f906e21f3d [platforms/hwcomposer] Support for hwcomposer 1.4 and 1.5 version
Summary:
HWcomposer version 1.4 introduced setPowerMode, which replaces the
blank(). This adds support for it. There are various code paths
possible,

- If KWin is built against hwcomposer 1.3 headers, then setPowerMode
code is not compiled in, and it will use blank to turn display off.

- If KWin is built against hwcomposer 1.4 headers, it will have
setPowerMode code path compiled in. It will be used only on devices with
1.4 and 1.5 version of hwcomposer.

This is slightly insane, because Android can report hwcomposer 1.5 even
when headers are of 1.4 version..

Test Plan: Tested this on Nexus 5X which reports 1.5 version of hwcomposer

0c5ca405cc Implement support for pointer constraints
Summary:
There are two types of constraints supported:
1. Pointer confinement
2. Pointer locking

In the case of confinement the pointer is confined to a given region of
the surface. This is comparable to general operation where the pointer
is confined to the screen region.

In the second case the pointer gets locked. That means it cannot move at
all. No further position updates are provided, only relative motion
events can go to the application. There is a hint about cursor position
update on unlock which is not yet implemented in KWayland::Server, thus
also not in this change.

The implementation in KWin grants the requests for pointer constraints
when the pointer enters the constrained region, either by pointer
movement or by e.g. stacking order changes. There is no confirmation
from user required to enter that mode. But we want to show an OSD when
the pointer gets constrained, this is not yet implemented, though.

Breaking an active constraint is relatively easy. E.g. changing the
stacking order will break the constraint if another surface is under the
cursor. Also (in case of confinement) moving the pointer to an
overlapping window breaks the confinement. But as soon as one moves the
pointer back to the window a constraint might get honoured again.

To properly break there is a dedicated event filter. It listens for a
long press of the Escape key. If hold for 3sec the pointer constraint is
broken and not activated again till the pointer got moved out of the
window. Afterward when moving in the pointer might activate again.

The escape filter ensures that the key press is forwarded to the
application if it's a short press or if another key gets pressed during
the three seconds. If the three seconds way fires, the later escape
release is not sent to the application.

This basic interaction is also ensured through an added auto test.

This change implements T4605.

2defd6bb64 [platforms/wayland] Use a ConfinedPointer if available
Summary:
This supports "grabbing" the pointer on right ctrl key just like on X11.
If the Wayland server supports pointer constraints protocol, the nested
Wayland compositor creates a confined pointer if the right ctrl key is
pressed.

On another right ctrl press the (active) constraint gets removed again.

To indicate the current state the window title gets updated. This also
implements window title support for the first time.

This change implement T4604.

fd07b1dc98 [libinput] Change unset of scroll method and acceleration profile
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:

This allows to pick a point on the screen which we need to screenshot
the screen under the mouse cursor and in future for color picking.

The screenshot effect provides two new dbus methods to (interactively)
select a screen or fullscreen. This allows spectacle to screenshot the
(full) screen with still having the user in control.

87150816c7 [libinput] Rework device config writing and save enum of ScrollMode as integer
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.

451bbb54dd [effects] Handle windowShown and windowHidden in fade effect
Summary:
For Wayland windows we can have a sequence of window unmapped
(windowHidden signal) followed by a windowClosed way later when the
application quits. This is for example the case with menus.

The result of this was that the fade out animation triggered when the
application quit showing all the already closed menus again.

This change implements a windowShown and windowHidden handler and
triggers the fadeIn/Out animation on it. If the window gets shown
again the existing fadeOut animation gets cancelled, so that it can run
again.

If a window gets closed for which a fade out animation has been run
already, it's not triggered again, thus ensuring that we don't see
zombie windows.

fbab204968 [effects] Add a screenshot dbus method which takes a file descriptor
Summary:
The idea behind this mode is to support applications like spectacle
(see T4458). The calling application passes a file descriptor (created
through e.g. a pipe) and the screenshot effect writes the captured image
into that fd.

The advantage over the existing variant which writes to a file in the
/tmp directory is that this is peer-to-peer between the requesting
application and KWin. No other application can get to that image.

The change also includes setting SIGPIPE to ignore. It showed that when
the reading side already cancelled the read prior to KWin writing out
the image we get a SIGPIPE which results in application termination,
which is not what we want in case of a Wayland compositor. The sigpipe
can be ignored as Qt (and libpng) handles that error just fine at
runtime.

cfdc1acbd3 [effects] Show info message in interactive window screenshot mode
Summary:
While taking an interactive screenshot we should inform the user about
what's going on, how to take the screenshot and how to cancel it.

For this the effect creates an EffectFrame with the required
information.
