e5fe3137b8 Fix the ignore struts multi-screen handling
Summary:
The checks in Client::adjustedClientArea were a little bit too
agressive, excluding also valid setups.

This change addresses the regression by keeping the actual intended
improvements in place.

The check in Client::adjustedClientArea is now only done for the
special case of desktopArea == area. This ensures that a strut excluding
a complete screen won't affect the overall workarea.

In addition new checks are introduced in Workspace::updateClientArea.
When calculating the new sareas a check is performed whether the
intersection with the adjustedClientArea would result in the sarea
becoming empty (thus a screen being completely removed). If that's the
case the geometry is ignored to not exclude a complete screen.

Interestingly I should have noticed that something with the logic is
odd. As the test case had two commented geometries which we now get.

2343a90aa5 UpdateClientArea from ShellClient::doSetGeometry if the ShellClient has a strut
Summary:
This ensures that resizing a panel updates the client area. On X11 there
is an event when the struts change, but on Wayland the struts are implied
from window type (panel) and the panel behavior, so we need to trigger it
manually.

58db477796 Fix the strut handling for wayland clients
Summary:
The implementation was broken as it transformed the QRects into QRegions,
subtracted the geometries and took the bounding rect again. In several
setups this could result in the strut getting ignored.

This change improves the calculation of the struts by creating a QMargin
which describes the area which needs to be subtracted from a screen rect.
The QMargin is only adjusted for the edge the window borders. We can
assume that a window with a strut needs to border a screen on Wayland.

With this change we are also able to support panels between screens.
On Wayland a panel placed on the right of a left screen affects the
maximization area of the left screen, but does not affect the overall
workarea.

1a23ab7cf0 [autotest] Add test case exposing problem of bug 363804
The test case sets up apol's screen setup and the panel as described
in the attachements in bug 363804. As the test shows the panel's strut
is incorrectly ignored.

bc25677caf Strut sanity checking: ignore struts which would exclude a complete screen
Summary:
Mostly meant for multi-screen setups: we don't want that a strut set on
a window on screen 0 results in screen 1 completely being excluded. Even
if that's strictly seen a client bug, it's better to just ignore the
strut from KWin's side.

The sanity check is implemented in Client::adjustedClientArea.

From a pure standard point of view this change is a EWMH violation and
thus can cause regressions: struts by clients no longer working.

A test case for struts is added, including some invalid combinations
whose strut is ignored with this change.
