Summary:
And finally nothing inside libkwineffects, libkwinglutils,
libkwinxrenderutils and kwineffect and kwin core uses KWin::display.
We are finally XLib free!
This change drops KWin::display and removes the include to QX11Info from
kwinglobals.h. And the libraries no longer need to link X11Extras. Due
to that removal a few seeming unrelated changes are required to add the
include where needed and linkage to X11Extras.
The biggest change is to x11 platform plugin which still needs the
display and caches it in the Platform and passes it to various places in
a way that the code doesn't need to be adjusted.

Summary:
The method xRenderBlendPicture created a static XRenderPicture on
first usage. To cleanup a XRenderPicture an xcb_connection_t* is needed.
As it's static the cleanup happens on exit handler and at that time Qt
already destroyed the xcb_connection_t*. With a certain chance this will
crash.
To expose the problem a Q_ASSERT(qApp) is added in the destructor of
XRenderPicture. Using xrenderBlendPicture() will hit this assert on
application exit. This is demonstrated by the added auto test.
The actual fix to the problem is moving the static variable out of
the method and introduce a global cleanup method just like the init
method. This is now called from Workspace dtor, so before application
goes down.

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.

Removes a diversion between X11 and Wayland. The base class Platform
creates an instance of class Edge with plugin implementations being
able to create a different type.
The X11StandalonePlugin does that and creates a WindowBasedEdge. For
this the implementation of WindowBasedEdge is moved from screenedges
into the plugin.
Unfortunately an ifdef is needed to make the screenedge test still
work as expected. This should be improved in future, e.g. have a good
way to load the platform plugin from the tests.

By moving XRandrScreens the creation of screens gets simplified a lot
as there is no need to have windowing system specific init code. It all
just goes through the platform.
This also marks the point where the first X11 specific code is removed
from kwin_wayland.

-use qstringliteral only when necessary (i.e. not in concat or comparison)
-use qbytearray instead of qstring when dealing with latin1 input and output (glplatform)
-use qstringref to extract numbers from strings (glplatform)
-define qt_use_qstringbuilder to optimize all string concatenations
-anidata: use ctor init lists, add windowType member initialization

This is the beginning of a new testing era for KWin: finally we are
able to test against a running KWin. This works by making use of the
new virtual framebuffer backend for Wayland. It starts a specific
Application subclass which is mostly a fork of ApplicationWayland.
The individual tests are able to influence the socket name and the
size of the virtual screen. This is supposed to be done in
initTestCase. To know when KWin is fully started one can use the
workspaceCreated signal of KWin::Application. KWin is not started in
another process, but the kwin library is used, so the test has pretty
much full introspection to everything going on inside KWin. It can
access the Workspace, WaylandServer, fake input events through
InputRedirection and so on.
Once the test KWin is running it's possible to connect to it using
KWayland::Client library. This allows to introspect the Workspace
to see whether all worked as expected (e.g. correct stacking order,
active window and so on).
This first autotest is mostly meant to illustrate how to setup a
test and how one can use KWayland::Client to interact with the mock
KWin. For more tests it is suggested to move the connections to the
Wayland server in the init() and cleanup() methods.
The change also affects the qpa plugin: the specific check to only
run in binaries called kwin_wayland doesn't hold any more. This can
now be overwritten by an env variable.
Please note that this first test will probably fail in the CI system
as it might not have XWayland which is needed by KWin.
With Qt 5.5 the physicalSize of a screen is broken if the X system does
not provide the XRandR extension. This caused our screen edge test to
fail on the CI system (Xvfb) due to approach window being based on the
dpi.
The problem itself is addressed for Qt in:
https://codereview.qt-project.org/126808
This change just worksaround till the change has made it into our CI
system (at which point the expected fails will break).

It's a convenient class to encapsulate the ICCCM WM_SIZE_HINT.
Instead of exposing just the properties it provides accessors for
the interesting parts and applies sanity checks.
A new implementation of the Screens interface is added which uses XRandR
directly instead of relying on QDesktopWidget. The implementation is
provided in a new implementation file screens_xrandr.cpp.
XRandRScreens comes with a unit test. Unfortunately it's rather difficult
to provide a proper unit test against XRandR. Xvfb (which is obviously
used on the CI system) doesn't provide the XRandR extension. Also on a
"normal" developer system one would not want to just execute the test as
the results are not predictable (number of available outputs?) and the
test would mess up the setup resulting in nobody wanting to execute the
test.
As a solution to both problems the unit test starts Xephyr as a nested
X server. This allows to have at least some limited tests against XRandR.
Nevertheless there are a few things which I was not able to test:
* multiple outputs
* no output at all
The nested X Server approach makes the interaction rather complex. Qt
opens it's connection against the main X Server thus QX11Info provides
a wrong connection and also KWin::connection() which is heavily used by
xcbutils and thus all the RandR wrappers have the wrong connection. To
circumvent this problem the test is GUILESS. In case it would call into
any code using QX11Info, it would probably either runtime fail or crash.

The new test does not cover ScreenEdges completely, so far the
following areas are handled:
* creating of the edges
* reserving of edges
* trigger callback
* cursor pushback
* blocking of edges for fullscreen active clients
This is a very interesting auto test as Screens uses both Workspace
and Client. Thus it operates in the "impossible to mock" area.
The solution is to provide mock includes in autotests and ensure that
when building the auto-test the mock header includes will be picked
first. There is now a mock class for Workspace and Client providing
just the API pieces used inside Screens.
As Screens is abstract and we cannot properly interact with
QDesktopWidget there is also a MockScreens class inheriting from Screens
and mocking the required functionality (by just operating on a list of
QRects).
The auto-test itself is only performing checks on the abstract class.
The mock class is indirectly tested by Screens calling into the virtual
methods. The test case is not yet complete, but looking quite good
already.
So far this new module contains:
* Display
* OutputInterface
Display manages the server socket and server event loop. In general it's
the entry point to any part of the server.
OutputInterface is the abstraction for the wl_output interface on server
side. An OutputInterface is created through the Display.
The auto tests for ConnectionThread and Output are adjusted to use the
internal server instead of starting Weston. Especially the Output test
could be extended to test much more as we have absolute control over
the server now.
The Wayland event queue is moved into a dedicated thread and a
new class is created for just creating the connection and listening
for events. The WaylandBackend creates the thread and uses an event
queue for the main thread.

Let's use the available API instead of duplicating code.
Nice side effect: client_machine.cpp doesn't include utils.h any more
which simplifies the unit test.

This is a specialized subclass of AbstractEffectLoader to load binary
effect plugins. It used the KPluginTrader to find all candidates to load.
The loader is able to detect incorrect ABI versions through the
pluginVersion() and uses the methods exposed by the new
KWin::EffectPluginFactory to check whether the Effect is supported and
should be enabled by default.
The unit test for this loader comes with two plugins: one is able to be
loaded and provides a supported and enabledByDefault method which can be
tweaked during the test to get all the conditions we want to test for.
The second plugin uses an incorrect plugin version and thus cannot get
loaded.
This implementation of the AbstractEffectLoader is able to to load the
scripted KWin Effects. It uses KServiceTypeTrader to find all the
candidates to load.
Effect loading gets split by the kind of effects KWin supports:
* Built-In Effects
* Scripted Effects
* Binary Plugin Effects
For this a new AbstractEffectLoader is added which will have several
sub-classes:
* BuiltInEffectLoader
* ScriptedEffectLoader
* PluginEffectLoader
* EffectLoader
The EffectLoader will be what the EffectsHandlerImpl is using and it just
delegates to the three other types of loaders. Thus the handler doesn't
need to care about the different kinds of effects. The loading is
supposed to be completely async and the EffectLoader emits a signal
whenever an Effect got loaded. The EffectsHandlerImpl is supposed to
connect to this signal and insert it into its own Effect management.
Unloading is not performed by the loader, but by the EffectsHandler.
There is one important change which needs to be implemented: the ordering
cannot be provided by the loader and thus needs to be added to the
Effects directly.
So far only the BuiltInEffectsLoader is implemented. It's not yet
integrated into the EffectsHandlerImpl, but a unit test is added which
tries to perform the various operations provided by the loader and the
BuiltInEffects. The test should cover all cases except the Check Default
functionality which is only used by Blur and Contrast effects. This
cannot be mocked yet as the GLPlatform doesn't allow mocking yet.
Used by Cursor to properly emit the mouseChanged signal which for
historic reasons includes the keyboard modifiers.
Again some fiddling around with the autotests and kcmrules needed to
make it compile. This needs improvement!
