An iconified task/window is in reality hidden. For example, when
`Show Desktop` action is performed, tasks are 'Minimized'. But when
tasks are minimized, they are 'Hidden'.
This property is essential to detect check if a window is truly
iconified or not when the hidden window previews is set to 'Always'.
A window can be moved to another activity externally, for example using
the user actions menu in kwin. The window model should notify the task
manager when such an event occurs.
Window activation is tracked to implement a new front-
end feature to activate the most recently active window (or fall
through to stacking order otherwise) subsequently.

Summary:
The tasks model now exposes a window's application menu object path and service name.
No update signals set up for XOrg; not sure what to listen for.
Test Plan:
See that the model has more roles and see that they're wired to the application
menu obiect path and service name on Wayland and XOrg.

Summary:
Includes, among other things:
* A refactoring towards supporting more than one desktop per window,
for an eventual virtual desktops / activities merge
* A scheme for process-internal window ids on Wayland as DND payload
so DND in and to the Pager works in the shell
* Implemented various previously missing behavior in WaylandTasksModel
such as implicit moves of windows to the current desktop on various
actions
* Expanded VirtualDesktopInfo API so the Pager can better abstract
over windowing systems
* Implicit internal sharing of VirtualDesktopInfo since there are many
more instances now
* Various cleanups
Still missing:
* Fixing the VirtualDesktops data role in the grouping proxy
* The protocol doesn't have desktop creation/destruction yet, so some
of the related logic is still missing
* Some FIXME TODOs in the code when I was unhappy with the current
KWayland API
This code is largely untested and subject to change.
Depends on D12820 and relates to T4457.

Maniphest Tasks: T4457
Differential Revision: https://phabricator.kde.org/D13745
Summary:
Some apps initially show their window with bogus/useless window
metadata and then update to useful metadata during early startup.
For example, LibreOffice sets WM_CLASS to soffice/Soffice and
then updates to libreoffice-writer/libreoffice. This leads to
a poor user experience on particular the Icons-only Task Manager,
but also the regular Task Manager depending on settings.
Depending on its configuration (and Icons-only Task Manager is
a particular set of configuration options, as far as the model
is concerned), TasksModel will try to sort a new window task
adjacent to its launcher task. The appearance of a new window
task also causes matching (in terms of identification) launcher
or startup tasks to be filtered out. To the user, this forms a
lifecycle of the launcher being replaced by the window in-place
(and a startup state inbetween, optionally but by default).
Prior to this patch, this sorting decision was only done once,
when a new window enters the source model stack. This meant the
LibreOffice window would initially be sorted into the "wrong"
spot (the bogus metadata doesn't allow us to relate it to its
launcher) and then, following the metadata change, stick to the
wrong position.
Simply changing the code to sort things again on any metadata
change would not have been good enough: Metadata changes can
occur at any time, and things should not just move around on
the user - this sort mode is called "Manual" for a reason. Also,
the visual result would still be poor: The window would initially
appear at the wrong position, then move to the right one a bit
later.
This patch takes the following approach:
* It adds a new config key to taskmanagerrulesrc for listing
ids of matching tasks to completely hide, and of course the
code needed to implement this.
* It adds LibreOffice' bogus initial metadata to this key, so
the tasks is initially hidden.
* The sort code skips over hidden window tasks in the sort
insert queue instead of moving them. The queue is marked as
stale then, and cleared on unrelated windowing system changes.
* It resorts when tasks are unhidden (i.e. once the metadata
update has occured and the task no longer matches the above
config key).
The visual result is that the startup notification on the
launcher spins a little bit longer than before, even though the
window has already appeared (although LO lags in filling in its
contents anyway), and then morphs into the window task
representation once the client has completed the window metadata
change. This happens in such a short order as to be more or less
imperceptible.
If startup notifications are turned off it's broadly the same,
minus the spinning.

Summary:
Also better sanity-checking of found services being app services
all around.
I'm not particularly happy about adding more X11 code outside of
XWindowTasksModel, but it means greater code reuse (in something that
has experienced unwelcome drift before) and there's a precedent in
LauncherTasksModel.

Summary:
This factors the app identification heuristic out of XWindowTasksModel
and turns it into generic code in TaskTools, producing a URL from a set
of window metadata bits. The key metadata is the 'appId', which is the
classClass part of WM_CLASS on X11 and PlasmaWindow::appId on Wayland -
which KWin sets to the former for XWayland clients. The result is much
improved support for XWayland clients in the Wayland session, with most
X clients now identified correctly.
As a side effect, the Wayland model gains access to the X model's much
superior code for grabbing a suitable icon, with PlasmaWindow::icon now
serving only as a fallback, similar to KWindowSystem::icon in the X
model.
Moving the code to TaskTools also means it now sports nice API docs.
The heuristic has seen some work as well, namely adding two passes that
try to parse the appId as a path to a desktop file, which we've never
seen on X11 but is common on Wayland - this heuristic was previously in
appDataFromAppId, which has been removed here since the shared heuristic
now satisfies this case.
Further, an old codepath handling kcmshell in a special way has been
removed. This is no longer necessary as we have better ways to tell
libtaskmanager about the KCM KService now, such as the .desktop file
window hint on X11 and a reliable appId on Wayland.
This patch also fixes some bugs around app data cache eviction and
telling model clients about data changes when cache eviction happens.
The X model didn't use to evict the cache and refresh when the
taskmanagerrulesrc file was changed at runtime, and the refresh for
sycoca changes didn't refresh the LauncherUrlWithoutIcon role. It does
now, and the Wayland model - which has gained taskmanagerrulesrc support
by way of the shared heuristic - now behaves in the same way.
The combined changes achieve near behavior parity between the X
and Wayland models when it comes to identifying apps by window meta
data, with the only exception being XWayland clients that need to be
identified by the (incorrectly used by the client developer) instance
name part of the WM_CLASS window property, which we can't access (this
case is so rare it's not worth handling at this time).
Depends on D5747, D5755.

Summary:
As this happens the screen filtering higher up in the proxy chain
culimating in TasksModel needs to be re-executed, as it compares
ScreenGeometry against a property value set on the model. Without
this update, tasks may disappear from views using TasksModel.
Mapping the trigger conditions to affected rows is deliberately
maximally coarse; see implementation comment in code.

Differential Revision: https://phabricator.kde.org/D3628
Summary:
This adds support for app ids which are absolute paths to .desktop
files to WaylandTasksModel, matching the heuristic in XWindowsTasksModel.
Behavior between the two models is made more similar in various ways,
such as matching codepaths for generating the ids inserted into the
KActivities database in requestNewInstance/requestOpenUrls (also the
X11 model was missing the notifyAccessed calls) and producing launcher
URLs.
Icons are still left to KWin however, instead of reading them from
KService (which is what KWin does in any case on Wayland) or from the
.desktop file. The latter might make sense, but to avoid duplicated
code would then best be done in KWin.
