The mutter tests require to run in a valid environment where a display
is available and a session bus, however currently we rely on the current
environment, and this may lead to unexpected behaviors.
So let's just ensure that a display is running through xvfb-run and
that a session bus is running in a temporary directory.
We also ensure to use the gsettings memory backend, even because by
setting TestEnvironment we ensure that no other env variable is leaked
to the test.

The cogl tests need to run with a display server set, however since we
use TestEnvironment, only the listed env variables will be exposed to
the test and so no DISPLAY will be set when launching it with
gnome-desktop-testing-runner.
As per this, just run the tests using xvfb-run so that we match what's
happening in CI and we ensure that the tests are run in a safe
environment.

When running multiple tests at once (with --all) as in the
installed-tests cases, we may open and close the display multiple times,
this leads to setting the alarm filter each time that the x11 display is
opened (causing a critical error) because we never disconnect from the
::x11-display-opened signal.
So disconnect from the signal on test destruction, to avoid this to be
emitted multiple times.

We first initialized the Wayland infrastructure, then the display, but
on shutdown, we first teared down the Wayland infrastructure, then the
display.
Make things a bit more symmetric and tear down the display before
Wayland. This however means we need to tear down some things Wayland a
bit earlier than the rest. For now this is a separate function, but
eventually, it can be replaced with a signal shared by the backend's
'prepare-shutdown' signal.

This way we can initialize without having any way to retrieve it via
some global variable. This isn't needed now, but will be once Wayland
infrastructure initializiation is done in a single step.

This is especially important as we might end up here when initializing
the Wayland infrastructure. Later that will be done in one step, meaning
the "get_default()" function will not work properly.

It might not be there when shutting down, so get it from a more managed
place. Note that this isn't strictly needed right now, but eventually,
the MetaWaylandCompositor pointer will be cleared using a g_clear*()
helper, which clears the pointer before freeing the instance, which
wouldn't work here.

This will allow us less awkward startup, where previously we had to
pre-initialize Wayland very early so Cogl could bind the Wayland display
when it initialized. Move things around so we bind the Wayland EGL
display when initializing the rest of Wayland infrastructure.

This object takes over the functionality of meta-idle-monitor-dbus.c,
meta-idle-monitor.c and meta-backend.c, all related to higher level
management of idle watches etc.
The idle D-Bus API is changed to be initialized by the backend instead
of MetaDisplay, as it's more of a backend functionality than what
MetaDisplay usually deals with.
It also takes over the work of implementing "core" idle monitors. The
singleton API is replaced with thin wrapper functions on the backend.

It just complicates things; we can't run them right now, so just get rid
of the runtime variability; just change the macros if you want to tweak
the test, would you be able to get it running.

Wayland support is not really a "backend" thing, it just lacked a better
place to store its instance pointer. Eventually we'll have a better
place, but prepare for that by initializing it together with the more
similar subsystems.

The rest of debug flag details are in util.c and util.h, make things
less scattered by moving the rest to util.c too.
While at it, put the coredump:ability setting needed for being suid
there too, so we have a common place for initializing "debug utils".

Commit 64c9c9c5b0 fixed monitor
screencasting, when fractional screencasting is enabled.
For the remote desktop usage, NotifyPointerMotionAbsolute() submits
the new mouse pointer position in addition to the stream, where the
mouse pointer was moved.
When not using fractional scaling, the mouse pointer position is
correct.
With the usage of fractional scaling, the mouse pointer position is
wrong, as the scale of the position is applied two times.
Fix this behaviour, by reverting the second scale by dividing by the
logical monitor scale, when fractional scaling is used.

When finalizing, the MetaDisplay instance will already be gone, so to be
able to gracefully tear down the clipboard integration, make sure to
close sessions before the display is closed, i.e. on prepare-shutdown.

The callback on_displayfd_ready() would unconditionally set the return
value to TRUE, regardless of the condition.
Use the GIO condition to determine if there was data written and adjust
the return value accordingly.

Some clients such as mpv might set the WM_TITLE as a UTF8_STRING based
on some unconverted/unvalidated metadata that is not actually UTF8. This
would then be set as the title of a MetaWindow (in the absence of a
valid UTF8 _NET_WM_TITLE). The shell then tries to use this window title
for things like the overview or the window switcher where it would
trigger an UTF8 validation error and leave the shell in an unusable
state.

This commit adds scaling support to clutter_stage_capture_into, which
is currently used when screencasting monitors. This is supposed to
fix graphical issues that arise when using fractional scaling.

We initialize, but might not start, e.g. when a test case just needs a
backend and doesn't start mutter. When cleaning up, we'll still try to
clean up Xwayland integration, and this commit handles cleaning up
without having made the mess.

We make objects inert when disabling the seat, but we requests may still
have effect. This is especially bad if disabling is followed by
destroying, but also means e.g. set_cursor() not doing an early out
after the pointer capability was disabled.
