Summary:
KWin::updateXTime only delegates into the platform API where the method
is a no-op. The actual implementation is moved into the X11 standalone
platform as it uses QX11Info which is non functional except on the X11
standalone platform.
This change exposes a problem with timestamp handling: on Wayland the
X11 timestamp does not get updated at all, causing e.g. window sync not
work correctly (c.f. bug 374881). We cannot implement the updating in the
same way as QX11Info/Qt xcb platform does it as that would introduce a
blocking roundtrip to XWayland which is dangerous.
As a side-effect this change removes linking to Qt5::X11Extras in kwin
core as it's no longer needed.

Summary:
The overlay window is only needed for the X11 based compositors. Given
that it is better suited in the X11 platform. Unfortunately it is not
possible to completely move it into the platform plugin as it is still
referenced in KWin core (e.g. SceneXRender). Due to that the
OverlayWindow in KWin core is turned into a pure virtual class with the
implementation being moved into the plugin.
The platform API gains a new virtual factory method which is only
implemented in the X11 platform.

Summary:
KWin already used C++14 constructs in a conditional way. This doesn't
make much sense today, it's better to just require C++14.
For KWin only gcc and clang are currently compilers of relevance. Gcc
supports C++14 since version 5 and defaults to C++14 since 6.1 [1].
Clang supports C++14 since version 3.4 [2].
An overview of compiler support in various distributions:
* Debian stable (stretch): gcc 6.3, clang 3.8
* Debian oldstable (jessie): 4.9, clang 3.5
* Ubuntu 17.04: gcc 6.1, clang 3.8
* Ubuntu 16.04: gcc 5.3, clang 3.8
* openSUSE Tumbleweed: gcc 7.1, clang 4.0
* openSUSE Leap 42.3: gcc ?, clang ? [3]
* FreeBSD: clang >= 34 in ports
* Slackware 14.2: gcc 5.3
This overview shows that every distro out there has at least one
supported compiler which can still compile KWin with this change.

Summary:
Weird NVIDIA behavior fixup part 2. Now that we do no longer freeze when
NVIDIA decides to create an OpenGL error on startup
(aefb5f4dd9), we experience a new issue.
KWin is terminating (no idea why, [1]) and at the same time the OpenGL freeze
protection thread is still running. So far we did not terminate the
thread on shutdown and thus we hit an abort in Qt.
This change ensures that we properly terminate the thread on shutdown.
[1] My current theory is that games terminate KWin, common pattern of
bug reports is "steam".

Summary:
There is a regression in WindowBasedEdge::soStopApproaching. Due to
only operate when the edge activates for pointer it is possible that
the cursor polling stays active. Explaining the situation:
1. Activate switch desktop when moving window
2. Start moving a window
3. Move mouse into the approach geometry
-> doStartApproaching activates as we are moving a window
4. stop moving window
-> doStopApproaching early exits as the position does not activate for
pointer any more - we are not moving a window
-> cursor polling is still connected and whenever mouse enters edge
approaching is started
The analysis shows that the check whether activates for pointer is wrong
in the case of stop approaching. If the edge started to approach, we also
need to stop approaching.
This change addresses the problem by turning the check into whether the
connection for cursor position update is set.
This is the third bug fix to the X11 screen edge handling after
introducing touch screen edges. This needs more manual testing by
everybody in the Plasma team who is still using X11.

To get an image from KWin to the screen in the DRM pipeline we combine a CRTC,
an encoder and a connector. These objects are static in the sense, that they
represent real hardware on the graphics card, which doesn't change in a
session. See here for more details:
https://01.org/linuxgraphics/gfx-docs/drm/gpu/drm-kms.html
Until now we used DrmOutput as the main representation for such an active
rendering pipeline. I.e. it gets created and destroyed on hot plug events of
displays. On the other side we had no fixed representation of the static kernel
objects throughout the lifetime of KWin. This has several disadvantages:
* We always need to query all available static objects on an hot plug event.
* We can't manipulate the frame buffer of a CRTC after an output has been
disconnected
* Adding functionality for driving multiple displays on a single CRTC (i.e.
cloning) would be difficult
* We can't destroy the last frame buffer on display disconnect because the CRTC
still accesses it and have therefore a memory leak on every display disconnect
This patch solves these issues by storing representations of all available CRTC
and Connector objects in DrmBackend on init via DrmCrtc and DrmConnector
instances. On an hotplug event these vectors are looped for a fitting CRTC and
Connector combinations. Buffer handling is moved to the respective CRTC
instance. All changes in overview:
* Query all available CRTCs and Connectors and save for subsequent hotplug
events
* Fix logic errors in `queryResources()`
* Move framebuffers, buffer flip and blank logic in DrmCrtc
* Remove `restoreSaved()`. It isn't necessary and is dangerous if the old
framebuffer was deleted in the meantime. Also could reveal sensitive user
info from old session.
Test Plan:
Login, logout, VT switching, connect and disconnect external monitor, energy
saving mode.

Summary:
To have touch events working we need to do memory layout changes on the
xcb events. This is fine for identifying the touch events which should
trigger the screen edge. But when passed on to Qt to have QtQuick windows
(e.g. Alt+Tab) handle the touch events, this results in a problem:
Qt itself does also the memory movement and then the movement is double
and touch events break.
To prevent this problem an RAII class is added which moves the memory in
the ctor and moves it back in the dtor. So during KWin's processing it
has the right memory layout and later on in Qt's processing it has the
proper "wrong" layout which Qt can fix again.

Summary:
Another regression from enabling touch support on X11.
The approach window for pointer input gets unmapped as soon as the mouse
enters the window. This ensures that mouse motion events are not stolen
from other applications. But with the touch events we did not even react
on the enter event if it's not activated for pointer. The result was an
area around the screenedge being blocked for pointer input.
This change only creates and maps the approach window if the edge is
activated for pointer input.

Summary:
Each Edge creates a SwipeGesture for touch activation. The swipe needs to
be a single finger starting from the edge into the screen for at least
20 %. The SwipeGesture and GestureRecognizer is extended to support the
use cases of the touch screen edge swipe.
New features supported by the gesture system are:
* minimum and maximum position
* a minimum delta for the swipe
* progress signal based on the minimum delta
* starting a swipe with a start point
The Edge has the progress signal connected to its approach signal, thus
visual feedback is provided through the screen edge effect.
The screen edge system supports touch only for the edges (corners are
too difficult to activate on touch screens). At the moment the following
features are supported:
* screen edge show/raise of windows (e.g. auto hidden panels)
* trigger the configured action
* trigger the configured callback function (e.g. script)
In future it might make sense to add a touch specific configuration
action to support different actions for screen edges activated by mouse
and touch.
