Non-current output modes were deprecated due to various reasons, e.g.
it's not possible to remove some nodes; two modes can have the same
resolution and the refresh rate but different flags, but wl_output.mode
fails to communicate that properly; the usefulness of non-current modes
is questionable. For more details, please refer to [1].

This is needed for keyboard grabs. If the seat is notified about a
keyboard event, it will need to forward the event to the grab object,
which in its turn will decide what should happen to the event.
This change renames methods that are used by the compositor to notify the
seat about input events.
There isn't anything special about the proposed naming scheme, for what
it is worth, it was established in weston. "notify" methods are used to
notify kwaylandserver about something, and "send" methods actually send
relevant events to wayland clients.
This rewrites the wl_seat protocol implementation to adhere to the new
design principles.
Effectively, we've been supporting wl_seat v7 so the version was also
bumped from 5 to 7.
With this design, a single PointerInterface manages multiple wl_pointer
objects. This makes the API tidier and allows implementing things such as
keyboard grabs more easier.
In addition to that, the PointerInterface doesn't inject its own frame
events anymore. It's up to the compositor to decide when it has to be
sent. However, the PointerInterface may still send a frame event if the
pointer focus changes.
Besides re-writing the pointer interface, this change, unfortunately,
also affects the implementation of pointer-gestures and relative-pointer
protocols because previously they were coupled to individual instances
of PointerInterface.
The main reason why we have factory methods is that up to some point,
kwayland had its own signal to indicate when globals have to be removed.
Now that all globals add destroy listeners for the wl_display object,
we don't have that signal. Most factory methods are equivalent to doing
new T(display).
Besides adding unnecessary boilerplate code, another reason to get rid
of the factory methods is to reduce the amount of merge conflicts. If
several persons work on implementing wayland protocols at the same time,
sooner or later someone will have to resolve merge conflicts in Display.
And make them public in th keyboard_interface, there's no point in
wrapping this in seat_interface with new approach

This was done mostly because I wanted to get rid of the Resource
dependency in AbstractDataSource so I can make our xwl bridge direct,
but this also fixes up some issues with object lifespan present in the
previous version and keeps all our clipboard code in-line.
The current xdg-shell wrappers don't match existing abstractions in the
xdg-shell protocol well, which makes it more difficult to refactor code
that is responsible for managing configure events and geometry in kwin.
Given that the xdg_decoration and the xdg_shell protocols are tightly
coupled together, I had to rewrite our wrappers for the xdg_decoration
protocol as well.
wl_shell_surface has been deprecated for quite a long time. Nowadays
most clients use the xdg-shell protocol to create desktop-style user
interface elements.
Summary:
Remove unused variables and members.
We were often storing the q of classes without ever needing them. I'd
just do it when it's useful. We do it in the private class so it can
always be added, removes boilerplate code.
Don't use std::move when returning temporary QImage. The compiler is
smart enough to know to do it but produces the warning "moving a
temporary object prevents copy elision".
Remove unused lambda captured variables.

Summary:
Right now it worked in kwin, but was in fact breaking the spec sending
buffers before it was configured.
There also seems to be an unclearly written (but very very sensible)
rule about comitting the surface after initial properties in order to
recieve the configure event.
After these changes it works in Weston too.

Summary:
This allows a dev to move the window before creating the popup which
is extremely useful in testing constraints. Also makes it very easy to
mod this code into a grabbing popup for other tests.
This patch also improve the painted surfaces to show the anchor rect
around where we place the popup which is easier for visual debugging.
No library code changes
Test Plan:
Ran the test
KWin doesn't position the popup according to all constraints

Summary:
Implement the "foreign" wayland protocol.
A client can export a surface with an unique string as handle,
then another client can refer to that surface and set an own surface as
child of that surface.
Potential use cases are out-of-process dialogs, such as file dialogs,
meant to be used by sandboxed processes that may not have the access
it needs to implement such dialogs.
The handle needs to be shared between the processes with other means,
such as dbus or command line paramenters.
The public api of the server side only tracks parent/child relationships as this is the only data kwin would need it for, the rest of the api is not exported so should be safer from eventual protocol changes
Test Plan:
the autotest works, but has a lot of random crashes when deleting surfaces,
unfortunately backtraces don't tell much and the crashes never occur when running into valgrind
behavior may still be wrong, depending on how the protocol is supposed
to work if more clients try to set the same exported surface as parent

Summary:
The main clever part that's not just boring boiler plate is how we
handle the structure change
A surface now has an XDGSurface which then has a an Xdg TopLevel or a
Xdg Popup
We need to fit this into the public API which assumes a surface has a
Surface or a Popup.
The old Surface is similar to the new TopLevel.
The shoehorning works by relying on the fact that a surface without a
role is pretty useless.
Clients create the surface implicitly with the toplevel or implicitly
with the popup.
The server only announced it has a new "XdgSurface" when it gets a new
zxdg_surface_get_toplevel.
----
Popup decisions:
- On popup creation the server should copy the current info from the
positioner and then it gets deleted. Given kwaylands job is to keep
state, we expose all these parameter via popup.
- Due to this positioner is not exposed as a resource anywhere.
- Server API is 100% backwards compatiable.
i.e new code will work identically with v5 clients.
- Client API is not. Grabs are called separately from the constructor,
and the parent surface changed to an xdgsurface, not a raw surface.
V5 code still works as-is, just not with the new constructors.
It seemed better to match the v6 (and what will be the stable v7) than
to try and do hacks and lose functionality.
Given the client needs to change the code to opt into V6 anyway. I don't
think this is a huge problem.
Test Plan: Current test still passes.

Summary:
Especially for Xwayland windows the compositor might not have a themed
icon name. Resulting in a task manager not having dedicated icons for
Xwayland windows.
This change deprecates the way how a compositor is supposed to set the
window icon. Instead of passing the themed icon name, it is now supposed to
pass the QIcon. In case it's a themed icon the existing way to pass to
the client is used.
Otherwise a new event is used to inform the client that there is an icon
- no data is transmitted at this point. The client can then create a
file descriptor and pass it to the compositor. The compositor serializes
the icon into the file descriptor and the client can read from it. This
all happens transparently on client side there is no api change at all.
The writing and reading of the icon is done in a thread. Due to that
Qt5::Concurrent is now a required dependency instead of an optional
dependency.

The test application creates a sub-surface tree consisting of overall
three surfaces:
* blue main surface
* red sub surface
* green sub surface to the red sub surface
All surfaces are in synchronized mode. There is a timer to turn the
green surface into yellow after five seconds.
Uses QWidgets to render a very small UI.
* lists each Output
* for each output shows whether dpms is supported
* and which dpms mode it's in
* and provides a button to change the mode
Server can set a themed icon name, client gets it directly turned into a
QIcon. That only works with QGuiApplications as can be seen in the
adjusted paneltest.
This change demonstrates how one can install a custom event dispatcher
before creating the QGuiApplication and how to process Wayland events
using the event dispatcher to e.g. start an Xwayland server prior to
creating the application.
It also allows to use
--platform wayland
on the test application. The wayland QPA plugin will connect to the
KWayland server started prior to creating the application.
Please note that such a setup will freeze unless QtWayland has commit
1e32e71 [1].

Instead of performing dispatchEvents for a hard coded number of
expected events from Xwayland, we use select on the pipe to figure
out whether Xwayland has started writing the display number. As long
as select does not indicate that the pipe is ready we need to dispatch
further events.
