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.
Otherwise we'll show a dangling cursor but otherwise the cursor will be
updated by other code paths, so we end up with a weird cursor in the
middle of the screen that doesn't move.
It is possible for updateOutputs to be called when a pageflip is pending.
Freeing a DrmOutput with a pending pageflip is not allowed (see ~DrmOutput assert - the page flip handler will be called on the freed memory, possibly leading to use-after-free).
This works around the problem by delaying the destruction with teardown().

In atomic setting mode, when external display tears down, it will blank
crtc with dump buffer by legacy api, then re-plug the external display,
the blank can not be removed. We think the blank is not needed in atomic
mode setting.

Currently in order to load an Xcursor theme, kwin uses libwayland api,
which looks really awkward because of the way how the compositor talks
to itself via the internal connection.
The main motivation behind this change is to limit the usage of kwayland
client api in kwin.
Since ScreenEdge no longer uses physicalDpiX() and physicalDpiY() from
the QPaintDevice class in favor of our own helpers, we need to ensure
that the X11 platform provides valid output physical dimensions.

We don't need to bind disabled outputs to surfaces that overlaps them.
This prevents error down the line and warnings about ignoring surface.enter events with Qt.

In previous code we used to update/show cursor even when the pointer
device was present, e.g mobile device. Guard it behind the cursor
enabled check.

Summary:
windowIcon.pixmap().bits() creates and deletes the QPixmap object.
Which means data is dangling when we call m_winInfo->setIcon()
Surprisingly harmless in real life.

Given that we now query the current X11 time stamp on Wayland, we can
enable synchronized resizing for Xwayland clients.
Differential Revision: https://phabricator.kde.org/D29250
Assume that Xwayland's current X11 time stamp corresponds to the system
monotonic time. Unfortunately, we cannot make roundtrips to Xwayland and
we cannot query the time stamp asynchronously because it may introduce
regressions in the standalone X11 window manager.

It turns out DRM connectors are not static and may change over time.
This patch refreshes them right before looking for new outputs.

Summary:
AbstractOutput::name() behaviour is changed so that it matches the X11
behaviour, showing an identifier like "HDMI-0".
XdgOutput.name is set to this name.
XdgOutput.description is currently set to the manufacturer name and
model, but it's not exposed to Qt so we probably don't care too much.
This should fix plasmashell changing applets when switching between X11
and wayland.
Test Plan:
Relevant unit test
I still need to run it on my laptop.
