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.

MetaDisplay does a lot of things, and is a central part to anything
window management. To let Wayland units have an easier time tearing
down, make it so that the Wayland infrastructure is terminated before
MetaDisplay.
This also makes sure that X11 support is turned off, so that we don't
stumble upon Xwayland terminating due to the Wayland socket connection
being broken. Will mitigate that in a better way in a later commit.

We might not be the only entity holding on to the X11 GdkDisplay,
meaning the X11 connection will stay alive indefinitely, e.g. if the gjs
context has some reference to it.
Avoid running into issues due to X11 connection errors by setting the
libX11 handlers to no-ops, so when we are terminating; that means the
GDK X11 connection can stay "alive" until its too late, and we'll just
silently ignore any connection errors that may happen due to the
lingering GDK display reference.

It keeps references to cursors, and cursors keep references to DRM
buffers. In order to be able to clean up on exit, explicitly destroy the
cursor tracker on shutdown.
We can't rely on GObject reference counting, as gjs might hold onto a
reference until it's garbage collected.

Various things, e.g, the renderer, the stage, either directly or
indirectly depends on GPU objects being alive during tear-down. Make it
so, by moving GPU cleanup after the other cleaning. This will allow
tearing down a couple of more objects.

The first phase happens early, which discards pending page flips,
meaning the references held by those page flip closures are released.
The second phase happens late, after other units depending on the KMS
abstraction, have been cleaned up.

We already swapped the front buffer, and even if it didn't get
presented, we should still swap our representation of the state, to not
get into a confused buffer tracking state.

All pointer a11y is a fabrication of Clutter backend-independent
code, with the help of a ClutterVirtualInputDevice and with some
UI on top.
On the other hand, MetaInputSettings is a backend implementation
detail, this has 2 gotchas:
- In the native backend, the MetaInputSettings (and pointer a11y
with it) are initialized early, before the ClutterSeat core
pointer is set up.
- Doing this from the MetaInputSettings also means another dubious
access from the input thread into main thread territory.
Move the pointer a11y into ClutterSettings, making this effectively
backend-independent business, invariably done from the main thread
and ensured to happen after seat initialization.

Compositor behaviour when calling `wl_data_device_manager_get_data_device`
for the same seat multiple times is not very clearly defined in
the spec and both Mutter and Weston currently don't handle
the DnD case properly.
While Weston handles DnD only for the last created data device,
Mutter, because of some internal reshuffling, ends up toggling
between two devices.
Properly handling this case requires some bigger changes. So
in order to behave predictable and in line with Weston,
only take the last created data device into account while
still keeping the previous created ones around.
The main affect client here is Firefox, which gets very
confused by the toggling behaviour and becomes more stable
with this patch.

Virtual Kernel Mode Setting (vkms) is a virtual /dev/dri/card* device
not backed by any actual hardware. It's intended for testing purposes,
e.g. to run tests suites with a reproducable setup, or in continuous
integration pipelines.
Currently mutter don't have any tests that can run on top of vkms, but
will eventually get that. To prepare for the ability to do that, and
having said kernel module loaded without causing wierd issues with any
active session, add an udev rule that tells mutter to ignore any vkms
device.
Otherwise, when vkms is loaded, mutter would detect it, assume it's a
regular monitor, configure it as such, thus add a region of the stage
that ends up nowhere, which isn't very helpful. It might also conflict
with running actual tests that need to interact with vkms if the active
session has taken control of it.
