Things such as Output, InputDevice and so on are made to be
multi-purpose. In order to make this separation more clear, this change
moves that code in the core directory. Some things still link to the
abstraction level above (kwin), they can be tackled in future refactors.
Ideally code in core/ should depend either on other code in core/ or
system libs.
This change adjusts the window management abstractions in kwin for the
drm backend providing more than just "desktop" outputs.
Besides that, it has other potential benefits - for example, the
Workspace could start managing allocation of the placeholder output by
itself, thus leading to some simplifications in the drm backend. Another
is that it lets us move wayland code from the drm backend.
AbstractOutput is not so Abstract and it's common to avoid the word
"Abstract" in class names as it doesn't contribute any new information.
It also significantly reduces the line width in some places.
The .clang-format file is based on the one in ECM except the following
style options:
- AlwaysBreakBeforeMultilineStrings
- BinPackArguments
- BinPackParameters
- ColumnLimit
- BreakBeforeBraces
- KeepEmptyLinesAtTheStartOfBlocks
Active output is a window management concept. It indicates what output
new windows have to be placed on if they have no output hint. So
Workspace seems to be a better place for it than the Screens class, which
is obsolete.
The order in which Xwayland surfaces are associated with X11 windows is
undefined, meaning that we cannot assume that a newly created X11 window
won't have a surface associated with it already.
When debugging modifier_only_shortcut_test in _waylandonly mode I saw
that it was failing, among other things, because some aspects were not
initialised.
This changes every test we have to run the new
Test::initWaylandWorkspace() that calls waylandServer()->initWorkspace()
but also makes sure that WaylandServer::initialized is emitted before we
proceed.
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.
The new signal is emitted when the Application has fully been initialized.
It allows us to change the startup sequence, for example create workspace
before starting the Xwayland server, without making any adjustments in our
test suit.
Summary:
As is KWin only had 1 Cursor which was a singleton. This made it impossible for
us to properly implement the tablet (as in drawing tablets) support and show where
we're drawing.
This patch makes it possible to have different Cursors in KWin, it makes all the
current code still follow the mouse but the tablet can still render a cursor.
Test Plan: Tests pass, been using it and works as well as before but with beautiful tablet cursors.

Summary:
Currently, we have only one shell client type - XdgShellClient. We use
it when we are dealing with Wayland clients. But it isn't really a good
idea because we may need to support shell surfaces other than xdg-shell
ones, for example input panel surfaces.
In order to make kwin more extensible, this change replaces all usages
of the XdgShellClient class with the AbstractClient class.
Test Plan: Existing tests pass.

Summary:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.
With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.
Renaming of Client to X11Client was agreed upon during the last KWin
sprint.
Test Plan: Compiles, the test suite is still green.

Summary:
Create output devices in virtual backend. For that the setVirtualOutputs call
can only come after the Wayland server has been initiliazied such that the
display exists to create the output and output device interfaces. Tests have
been adjusted for that.
Test Plan:
```
98% tests passed, 3 tests failed out of 148
Total Test time (real) = 362.97 sec
The following tests FAILED:
33 - kwin-testInternalWindow (Failed)
39 - kwin-testPointerInput (Failed)
101 - kwin-testMoveResize (Failed)
```
Failing of these tests looks unrelated to the change.

Summary:
So far KWin did not re-evaluate the window rules when the Client's
window class changes. Window class is the main (static) feature the rule
selection is based on. For dynamic changing mapping features like caption
KWin does re-evaluate the rules.
The reason for KWin to not evaluate when the class changes is that KWin
expects the class not to change. From ICCCM section 4.1.2.5:
> This property must be present when the window leaves the Withdrawn
> state and may be changed only while the window is in the Withdrawn
> state. Window managers may examine the property only when they start
> up and when the window leaves the Withdrawn state, but there should be
> no need for a client to change its state dynamically.
Unfortunately there are prominent applications such as Spotify which
violate this rule and do change the window class dynamically. While this
is a clear ICCCM violation there is nothing which really forbids it (may
not != must not) and nothing which forbids KWin to react on changes.
As also libtaskmanager started to react on it, it makes sense to also
hook up the required bits for window rules. After all KWin detects
changes to the window class for some time already and has the
functionality to evaluate the rules. So all there is, is one connect
which improves the situation for our users, while at the same time it
should be rather risk free. If a setup window rule breaks after this
change it's due to the client not being ICCCM compliant.
Test Plan:
I don't use any of the affected applications, so it's only
tested with the new added unit test.

Summary:
We used to have a toLower when reading the rule. This was removed with
4f7edb8 which turned it into a case sensitive matching to fix a
regression.
But this created another regression: existing rules written lower case
are no longer matched.
This change makes the role matching case insensitive again.
