Summary:
Windows we can't find an app icon for using the normal means
get the icon used by the windowing system in the Task Manager.
This fallback icon was then not updated when changed on the
window, only occasionally as a side-effect of cache evictions
and model data requests.
This patch notes which windows hit the fallback path, and for
those windows evicts the cache when the icon changes on the
window, causing it to be re-retrieved from the windowing system
as views respond to the dataChanged signal for the decoration
role.
Evicting the entire cache is a little bit costly, but:
- This is a fallback codepath.
- Apps conventionally update title and icon in one go, meaning
the cache is often already getting evicted anyway.
- Icons don't change that often.

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:
This introduces a TryIgnoreRuntimes key in taskmanagerrulesrc's Settings
group that can be used to list known runtime executables that can be
ignored when trying to identify the application owning a window by the
command line of the associated process.
A concrete example is the Frozen Bubble application. Frozen Bubble
installs a frozen-bubble.desktop with Exec=frozen-bubble, yet its
WM_CLASS is ("perl", "perl") and its command line is as follows:
/usr/bin/perl /usr/bin/frozen-bubble
The existing servicesFromPid() (now split into servicesFromPid() and
servicesFromCmdLine()) does not find the frozen-bubble service because
it works with the leading executable in the command line.
In this patch, TryIgnoreRuntimes is introduced with a default of
"perl". In the new code, after the initial command line matching pass
fails, TryIgnoreRuntimes is checked for whether the leading command
line executable is on the list, and if so, a second command line
matching pass is run with the remainder of the process' command line,
now succeeding.
Note that the approach of "try one more thing" rather than checking
against TryIgnoreRuntimes first is deliberate: The Exec= key in many
.desktop files contains a complete command line prefixed with the
runtime executable. In those cases we don't want to ignore the runtime
executable, or matching would fail.
To complement this, the "perl" WM_CLASS is added to the
MatchCommandLineFirst rc key. Due to the shoddy metadata Frozen
Bubble already ended up in servicesFromPid() regardless, but this
saves some busywork for this WM_CLASS, which can reliably be presumed
bad.
The patch also fixes a small logic error in the match-command-line-
without-arguments block, where the result of a KServiceTypeTrader
query was ignored and immediately overridden by another.

Summary:
We currently match Krita by Name. It's classClass is "krita",
but its DesktopEntryName is org.kde.krita.desktop. However,
Krita also installs numerous additional .desktop entries to
associate more file types by itself, all of which match by
name, and the first one in the list isn't the right one. All
of those extra .desktop files are NoDisplay=true however, so
we can filter them out, which brings the match list down to
the one and only .desktop file we care for.

WM_CLASS instance and general classes are checked against StartupWMClass

This matches the fd.o spec more closely and makes Chrome Apps and

win.

Summary:
Hitting again a bug where switching desktops shows a delay of several seconds
before the taskbar updates, I noticed that this code path was called 81
times in 7 seconds (!) for kmail (maybe because I start it from cmdline
rather than via a .desktop file).
After the 4 slow calls to KWindowSystem::icon it seems definitely worth
it to cache the result.
Overall the main performance bug is still there though, switching
desktops is still slow, but now all backtraces show QML triggered
by model/view dataChanged signals, no idea yet, other than hoping
for the pending QSFPM patches to help with this (no need to re-sort
when the dataChanged roles are unrelated to the roles used for sorting).

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.

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.

The latter is a thematically related cleanup I did along the way.
The strange original code was probably to handle the NULL_UUID, but

developed the ability to do this since.

Summary:
Utility windows (NET::Utility/_NET_WM_WINDOW_TYPE_UTILITY) should
not be on the Task Manager, but they should be on the Pager. This
patch achieves this by evaluating the window type in the
AbstractTasksModel::SkipTaskBar data role.
I considered the alternative approach of making a new
AbstractTasksModel::IsUtilityWindow (or similar) data role and
adding a pass to evaluate it to TaskFilterProxyModel, then
configuring the filter models in TasksModel and the Pager backend
differently. But this is not very extensible. Then I realized that
AbstractTasksModel data roles do not and should not reflect X11
idioms anyway; the point of the library is to abstract for the
purpose of UI, and what XWindowTasksModel considers "SkipTaskBar"
is really an implementation detail. This makes all the more sense
considering on Wayland we have no notion of window types (beyond
"popup") yet, and don't quite now how it's going to evolve.
Various API docstrings have been changed to better reflect that
the meaning of the data role doesn't map to anything specific in
the tasks.

This makes grouping work for apps we can't find on the system and
can't produce a launcher URL for, such as wine clients. Any better
app will use our superior codepath, the wonky ones like wine then
get left to making sure their WM_CLASS Class makes sense as per the
ICCCM spec.
Of course this doesn't work for XWayland clients on Wayland though.
