The InputConfig was introduced to handle tests that don't have valid
kwinApp object. Those tests have been either reworked or dropped, so
let's drop the InputConfig to tidy the config stuff.
These concepts are hard to map to InputDevice abstractions, so remove
them and let kwin use its own internal keymap instead (rather than
get it overridden by the host compositor's keymap) and track modifiers
based on the events it receives.
If the goal is to have these at any cost, I think the way out of it
would be to provide wayland backend specific signals. I would like to
avoid doing that though because it breaks encapsulation and we would
need some casts in kwin to wire in these events.
reconfigure is hooked up to a config watcher that is applicable on X11
and wayland.
A runtime check is added to reconfigure, if we're not initialised we
have nothing to reconfigure. initialise calls reconfigure at the end of
the method.
This makes KWin switch to in-tree copy of KWaylandServer codebase.
KWaylandServer namespace has been left as is. It will be addressed later
by renaming classes in order to fit in the KWin namespace.
The .clang-format file is based on the one in ECM except the following
style options:
- AlwaysBreakBeforeMultilineStrings
- BinPackArguments
- BinPackParameters
- ColumnLimit
- BreakBeforeBraces
- KeepEmptyLinesAtTheStartOfBlocks
This ensures that we get a warning if the config header is not included
instead of compiling the code as if it was disabled. Interestingly, some
checks already used #if KWIN_BUILD_*, so those were generating -Wundef
warnings when the feature is disabled. Commit 886173cab assumed that all
those features were already 01, so this unbreaks the build if any of the
features is disabled.

Same as real hardware wl_keyboard, key should be sent before modifier
change. For example, Left Ctrl press and release should produce
key events in the order of Control_L and Control+Control_L.
The main motivation behind this change is to prepare input abstractions
for virtual input devices so the wl_seat can properly advertise caps or
the cursor getting properly mapped/unmapped when a fake pointer is
added/removed on a system without a hardware mouse connected.
With this, there are three abstractions - InputDevice, InputBackend, and
InputRedirection.
An InputDevice represents an input device such as a mouse, a keyboard, a
tablet, etc. The InputBackend class notifies the InputRedirection about
(dis-)connected devices. The InputRedirection manages the input devices.
Such design allows to unify the event flow for real and virtual input
devices.
There can be several input backends active. For example, the libinput
backend and an input backend that provides virtual input devices, e.g.
libeis or org_kde_kwin_fake_input.

BUG: 375518
Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.
This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.
We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
If user set custom name for the layout, country flag is not displayed.
Instead, Display Name is shown in the applet.
This reveals shortcomings in current DBus API design.
We need more data to pass over DBus to fix this.
Then, multiple improvements are possible:
- fix aforementioned bug
- add flags to context menu
- display correct translated Layout Name in the context menu
- simpler, cleaner DBus API and applet implementation
- etc.
When deciding do OSD or not, we need to consider not only last saved layout,
but last actual layout also, when comparing it to current one.

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.
We were calling it from tests that were not running a KWin::Application
and not even including the symbols from main.cpp and main.h. The only
reason they linked was that it was static_casting up the QCoreApplication.
Summary:
Qt has its own thing where a type might also have corresponding list
alias, e.g. QObject and QObjectList, QWidget and QWidgetList. I don't
know why Qt does that, maybe for some historical reasons, but what
matters is that we copy this pattern here in KWin. While this pattern
might be useful with some long list types, for example
QList<QWeakPointer<TabBoxClient>> TabBoxClientList
in general, it causes more harm than good. For example, we've got two
new client types, do we need corresponding list typedefs for them? If
no, why do we have ClientList and so on?
Another problem with these typedefs is that you need to include utils.h
header in order to use them. A better way to handle such things is to
just forward declare a client class (if that's possible) and use it
directly with QList or QVector. This way translation units don't get
"bloated" with utils.h stuff for no apparent reason.
So, in order to make code more consistent and easier to follow, this
change drops some of our custom typedefs. Namely ConstClientList,
ClientList, DeletedList, UnmanagedList, ToplevelList, and GroupList.

Summary:
This command line option is useful for KWin in embedded use case. That
is when KWin is just used as a compositor for one application instead of
a complete desktop environment. In such a setup global shortcuts are not
wanted and interfere with the application. E.g. one does not want Alt+F4
to close the window, that would render the system unusable.
This change introduces a command line option and disables the following
event filters and spies:
* global shortcuts
* modifier only shortcuts
* terminate session
* virtual terminal switching
* screen edges
KGlobalAccel still gets inited, otherwise the (non-functional) binary
would be launched when KWin registers it's global shortcuts.
Test Plan:
New test added based on existing tests for the global
shortcuts, ctest passes

This change brings improved num lock support to KWin. The modifier state

config is read and the NumLock key is evaluated. If the requested state
does not match the current num lock state the state is swapped.

Summary:
So far KWin started to filter out the escape key as soon as it gets
pressed. This was done by unsetting keyboard focus. The idea was to
reset keyboard focus when it is only a short press and that then the
keyboard state is correct for the application. But in practice this
does not work. The only application currently supporting pointer
constraints (Xwayland) does not do anything on a key which is pressed
when gaining keyboard focus. The result is escape not working in
pointer constrained Xwayland windows.
This change addresses this problem by changing the interaction to only
unset keyboard focus when our break constraints condition is met. This
should also result in the application not handling the key release, but
it means it gets the key press. Unfortunately I don't have a good way
to test.

Summary:
Consider the case that capslock gets pressed and released.
In the case of Weston we have a sequence of:
1. Key press event
2. Modifier changed event
3. Key release event
4. Modifier changed event
KWin however used to send the events in the following sequence:
1. Modifier changed event (on key press)
2. Key press event
3. Modifier changed event (on key release)
4. Key release event
It looks like Xwayland is not able to properly process the sequence
sent by KWin. And in fact KWin's sequence is wrong as it sends a state
which does not match. We report that the caps lock is pressed in the
modifiers prior to the application getting informed about the key press
of caps lock.
This change aligns KWin's implementation to the behavior of Weston. The
main difference is that when modifiers change Xkb internally caches the
serialized modifier states. And KeyboardInputRedirection just forwards
the modifiers to KWayland::Server::SeatInterface once the processing has
finished. SeatInterface ignores the forwarding if no states changes, so
it is fine to do it that way.
BUG: 377155
Test Plan:
Not yet tested with an affected Xwayland as I only have 1.18 and the
problem started with 1.19. But verified the sequence of events with WAYLAND_DEBUG

Summary:
The functionality regarding triggering modifier only shortcuts is moved
out of Xkb - where it doesn't belong to - and is turned into an input
event spy listening for the changes it is interested in. Previously
the state got queried by asking e.g. for the pressed buttons, now it's
tracked directly.
The X11 side needs a larger change due to that as now pushing the events
into Xkb does not trigger modifier only shortcuts any more. Instead the
"normal" way through the platform API needs to be used which triggers the
processing of filters and spies.
The problem here is that our redirections only process events if they are
inited and that only happens on Wayland. We cannot call init on them as
that would create all the Wayland filters and spies and processing would
probably break. As an intermediate solution the spies are now processed
and there we know that it won't matter. A future solution would be to
remove the init checks completely and just send through both filters and
spies and ensure that on X11 only the supported ones are loaded.

Summary:
So far KWin parsed the kxbkrc at multiple places (once in Xkb, once
in KeyboardLayout). This is now replaced by one KSharedConfigPtr hold
by kwinApp, just like the normal kwinrc. The KSharedConfigPtr is now
passed to Xkb.
As a nice side effect this makes it easier to test keyboard layout
changes as we can now properly mock the keyboard configuration. Thus
this change also comes with an autotest for loading keyboard layout
configuration. This is becoming more and more a need as we start
getting bug reports for layout specific issues like global shortcuts
not working with Greek layout.

Summary:
So far the keyboard repeat handling was triggered directly from
KeyboardInputRedirection::processKey. With the introduction of
InputEventSpies it is no longer required to be done like that, we can
split it out into a dedicated spy.
This means that processKey only has to care about processing the key
and allows us to better extend in future. So far keyboard repeat is
only functional for libinput based platforms. But it should also be
possible to use it in nested setups. By splitting it out we can
prepare for that.
Test Plan: Auto-test using repeat still passes
