Summary:
Commit 5d9027b110 introduced a regression in TabBox by using the generic
framework inside KWin to test for same application. What I did not
consider was that the code in TabBox was "broken by design". It didn't
use the generic check as that is too strict and considers windows from
different processes as not belonging to the same application. But this
is not wanted in the case of TabBox.
On the other hand the change itself is an improvement to also support
Wayland in a better way and not have special handling situations. Thus
just reverting would not help.
Instead this change addresses the problem by extending the internal API
and to allow more adjustements. So far there was already an
"active_hack" boolean flag. This is extended to proper flags with an
additional flag to allow cross application checks.
The checks in Client which would filter out different applications check
for this flag and are skipped if set. In addition ShellClient also adds
support for this flag and compares for the desktop file name.
Thus we get in TabBox the same behavior as before with the advantage of
having a better shared code base working on both X11 and Wayland.

Test Plan:
Started two kwrite processes on X11, clicked new in one of them,
used Alt+` and verified that there are three windows shown.

Summary:
So far KWin always updated the active window property even if the actual
window id hasn't changed. E.g. if a Wayland window was active and another
Wayland window gets activated the window id was and stays 0.
Nevertheless KWin updated the property causing wakeups in X server and
any application listening to property changes on the root window.
Futhermore this situation is an information leak: we leak when a Wayland
window gets activated to X11.
To solve this problem RootInfo caches the active window id and only
updates if it changes.
Test Plan:
Verified with xev -root that the active window does not get
updated needlessly.

Preparation for X free KWin. Code is called for both X11 and Wayland
windows. So make it not crash if we would not have an X server.

Summary:
On X11 one needs to force activate a panel to pass it focus. This change
implements something similar for Wayland but a little bit more stateful
by using a request on the PlasmaShellSurface. If set KWin will activate
the panel.

QDialog or at least QMessageBox does this and I doubt Lubos' idea was to
"allow focus stealing if the client nags enough" - switching the VD is a
major interrupt and prevented when a new window shows up.
It should not be possible to stomp on ground and then receive
focus - notably not on the other desktop.
I assume the original idea was to let clients distribute focus *inside*
across virtual desktops, maybe also permit when no client was active,
but hardly otherwise.

This allows to pin the focus on certain window as well
as to more easily give it away on others (typically launchers)

AbstractClient now also supports mainClients, so we can do the
fullscreen window check on setActive in a general way. This ensures
that we do get proper stacking changes for activating fullscreen
shell clients.
This fixes yet another regression from the transient refactoring.
The passed in client might be null, so we need a nullptr check. There
are several already in that code.
Was tricky given that I removed a cast there.
AbstractClient::mainClients is virtual and overriden in Client,
allMainClients has only a common implementation in AbstractClient.
In activation.cpp we still need one case where a temporary ClientList
needs to be constructed. Once transients are fully migrated that should
be removable again.
othrwise closing a keepabove or desktop group
window would activate some random window and break
the state as a side-effect

instead of "just" the direct transient.
Reason is that many windows set dialogs transient
for an entire group (eg. all their document windows)
If there's only one window, that is equivalent to choosing
the direct transient leader.
Originally I wanted to allow this for any amount of
leaders and picked the first one, but that means if
you open 2 kwrite windows (from one PID!) and an
open dialog for kwrite #2 and close the latter,
the focus would be passed to kwrite #1
-> The focus chain is the better choice here.
(One could look up all leaders in the focus chain
OR the stack and use the most recent/top one,
but that's probably voodoo)

Moves the implmentation to AbstractClient. Methods are no longer virtual,
setActive calls a virtual protected method which is implemented in Client
for Client specific activation code.
The change is mostly straight forward. Effects are straight forward
adjusted. Client::findModal is moved up, this causes still a few
dynamic_casts to Client. Mostly because Workspace::activateClient still
operates on Client.
apparently some clients (randomly?) set
_NET_WM_USER_TIME to 0 (recorded for libreoffice,
audacity and perhaps firefox), so we allow to
forcefully have them accept the focus here

We are only using the UrgencyHint, InputHint and GroupLeader from
WMHints. Those are provided by NETWinInfo, so we can use the
functionality provided by NETWinInfo instead of calling XGetWMHints.

Use the timestamp from the xcb event which triggers the update whenever
possible. If we don't have access to the latest event, let's at least
update our own xTime prior to using it.
Slightly unrelated change included: Group switches the userTime from
XLib datatype to xcb datatype.

The Xcb::Property can wrap the xcb_get_property call and provides
convenient access methods to read the value of the reply with checks
applied. For this it provides a templated ::value method for reading a
single value or reading an array. There's also a ::toBool and
::toByteArray which performs the conversion directly with default values
for the type and format checks.
Xcb::TransientFor is changed to be derived from Property instead of
Wrapper directly, so that the reading of the property value can be
shared.
Xcb::StringProperty is a convenient wrapper derived from Property to
handle the reading of a string property providing a cast to QByteArray
operator. This replaces the ::getStringProperty from utils. Though the
separator functionality from ::getStringProperty is not provided as that
is only used in one function and handled there.
All the custom usages of xcb_get_property or getStringProperty are
replaced to use this new wrapper. That simplifies the code and ensures
that all properties are read in the same way.

Only delegated to Cursor::pos() anyway, so let's just use that directly.
Fixes the annoyances of having to mock it in the unit tests which include
utils.cpp.

Instead of passing the macro based Predicate to findClient it now
expects a function which can be passed to std::find_if.
Existing code like:
xcb_window_t window; // our test window
Client *c = findClient(WindowMatchPredicated(window));
becomes:
Client *c = findClient([window](const Client *c) {
return c->window() == window;
});
The advantage is that it is way more flexible and has the logic what
to check for directly with the code and not hidden in the macro
definition.
In addition there is a simplified overload for the very common case of
matching a window id against one of Client's windows. This overloaded
method takes a Predicate and the window id.
Above example becomes:
Client *c = findClient(Predicate::WindowMatch, w);
Existing code is migrated to use the simplified method taking
MatchPredicate and window id. The very few cases where a more complex
condition is tested the lambda function is used. As these are very
local tests only used in one function it's not worthwhile to add further
overloads to the findClient method in Workspace.
With this change all the Predicate macro definitions are removed from
utils.h as they are now completely unused.

As can be seen in [1] the patches to KWin were in CVS HEAD before the
protocol got standardized and it never got any adoption. It's neither in
the NETWM spec, nor implemented in Qt4 nor in Qt5. KWin did not even add
the protocol to the NET::Supported property.
Thus it doesn't make much sense to keep a protocol which nobody speaks.
Still the code around the protocol is kept and also the names are kept.
Only difference is that Client::takeActivity got removed and the code
moved to the only calling place in Workspace. Motivated by that change
the enum defined in utils.h is moved into Workspace, it's turned into
a proper QFlags class and used as a type in the method argument instead
of a generic long.

They just delegate to same method from NET:: and those were used already
quite a lot in KWin already as classes inherit from NET and thus get it
directly.
