If the output is off a double tap (touch) can re-enable it. The two
taps have to happen in the double click interval (we don't have
something better and it kind of matches) and have to be by only one
touch point. If there are multiple touch points it's not considered
as a double tap. A todo is to restrict the possible distance of the
two taps to one thumb.

So far the DrmOutput connected to all input events when going into
power saving. As we now have the input filters it's better to just
install a filter when an output goes into powersave and remove the
input filter again when all outputs are enabled again.
To make this work InputRedirection gains a new method to add a new
filter as the first filter. This is a potentially dangerous method
as it allows to have a filter before LockScreenFilter gets the
events. But in case of DPMS it's something we actually want.
A nice new feature possible with the input filter is that we can
filter out the event which re-enables the outputs. Thus when getting
on a system with output off and screen locked, the first key hit
doesn't go to the lock screen.

BUG: 341201
Fixed-in: 5.6.0 (Wayland-only)
This is needed to make KWin build-able on non-Linux, but is actually
only a workaround. The dependency should also be available on non-Linux.
This disables the EGL integration in the Wayland backend (QPainter still
available) and the EGL fallback in the qpa plugin (preferred context
sharing still available, but requires a working OpenGL Scene).

The implementation of VirtualTerminal is too linux specific and doesn't
compile on e.g. freebsd. Currently the most usage is in combination with
libinput. Only usage is:
* libinput related functionality in InputRedirection
* backends without custom input handling
Thus binding the feature to whether libinput is available is currently
the least invasive approach to get it compile on non-Linux.
In the long run this needs a different solution. The functionality
provided by VirtualTerminal is required and without the backends don't
work. It's needed to get notified about VT switches, when KWin needs to
stop rendering. So a solution for non-Linux needs to be found if
non-Linux wants to provide Wayland in future.

All backends already have an init method so far called from the ctor.
This change moves the call to init out of the OpenGL backends and makes
it the responsibility of the creating code to also call init on the
backend.
This change makes it easier to have virtual methods being called during
the initialization.
The backend is prepared for managing multiple x11 windows. Currently
it's still only one window, but it's all internally working through
the architecture for multiple windows.
We use the hw module's backlight and set the color to either 0
or FF depending on whetehr we want to have the screen on or off.
This turns the backlight off properly. It is bound to the toggleBlank
functionality so that we always turn on/off the backlight depending
on whether our compositor is on or off.
In addition we listen to key release events on the power button to
toggle the state.

If we don't have a dedicated device identifier we should use the default
mechanismn which involves using the WAYLAND_DISPLAY or WAYLAND_SOCKET env
variable.
We are going to switch to a proper nested approach similar to the
x11 backend. Given that we don't want to run on fullscreen anymore
but just open a nested window.
This gives a better tear down experience as it goes to black instead
of showing outdated screen and also it disables vsync which fixes a
crash on teardown.
For the functions from GL_FOO_robustness we want to resolve it by
ourselves in order to add a custom implementation if it's not available.
Unfortunately once epoxy.h is included this breaks as epoxy defines the
names and so through the preprocessor epoxy always wins.
So we need different names: all functions from robustness get a "kwin"
prefix and the usage is changed everywhere in kwin source code.

Begin of proper multiscreen support!
We load configuration sets for the connected outputs. Each set of
screens represents a unique configuration. For that we use the md5
sum of the edid+connector as uuid of an output. Each of the md5 sums
is then used to create a uuid of the output set. We can be quite certain
that this will generate unique ids for the use cases we will face.
The uuids are used as group names. And from there we read the global
position.
The uuids are considered internal information. It is not intended for
users to configure manually in the config file. The intended way to
configure will be the OutputManagementInterface which recently got added
to KWayland. Once KWin applies a configuration it will store it to config
so that it can be loaded on next startup.
The configuration looks like:
[DrmOutputs][abcdef0123][0123abcdef]
Position=0,0
[DrmOutputs][abcdef0123][fbca3bcdef]
Position=1280,0
This is an example for two outputs set next to each other.
