This will make clients immediately aware of the output disappearing,
while still allowing for a grace period of 10 seconds for attempting to
bind to it before it turning into a protocol error. This API added as
part of wayland 1.18.
This requires us to not add the output resource to the output resource
list, if the output was made inert. This effectively makes the resource
useless, but that is harmless, since shortly after, the client will
clean it up anyway.

This will be crucial when we start to remove the global directly when an
output is removed, as that means Xwayland might have removed the output
before we managed to get our queries in.

We setup Xwayland in an early phase of the X11 display, before we had a
MetaX11Display, and teared down in a couple of places happening when
tearing down the Xwayland integration if the X server died or
terminated. It was a bit hard to follow what happened and when it
happened. Attempt to clean this up a bit, with things being structured
as follows:
* Early during X11 display connection setup, only setup the rudimentary
X11 hooks, being the libX11 error callbacks, and adding the local
user to XHost.
* Move "initialize Xwayland component" code to a new
'x11-display-setup' signal handler. Things setup here are cleaned up
in the 'x11-display-closing' handler.
* Connect to 'x11-display-setup' and 'x11-display-closing' up front,
and stay connected to these two.

This old handling of session files looked on ~/.mutter, which has
been unused and unsupported for a long time. It also had paths were
the GError was leaked. Fix both by dropping the legacy code, and
falling back to the common error paths.

This warning is actually dead code, since should_be_mapped and
must_be_realized are always set to the same value, so it does not
make sense to check for "a && !b".
Turn this into an assert so we avoid the dead branch, but do not
remove the variable duplication so the more aptly named variable
is used where it belongs, for clarity.

When grabbing the devices, there's no error paths that would quit
late enough that both pointer and keyboard would need ungrabbing,
so the keyboard checks were dead code.
Fix this by dropping the boolean variable checks, and adding goto
labels to unroll the operation properly at every stage.

The monitor orientation tests do a lot of things in sequence. Replace
some of the comments with g_test_message() so that the log from a failed
test gives us a better idea of how far we got.

Previously, we were waiting up to 300ms for the signal, then proceeding
anyway. However, 300ms is not necessarily long enough to wait on an
autobuilder that might be heavily loaded, particularly if it's a non-x86
with different performance characteristics.
Conversely, if mutter responds to the D-Bus signal from the mock sensor
before we have connected to the signal, then we cannot expect to receive
the signal - it was already emitted, but we missed it. In this case, we
need to avoid waiting.
One remaining use of wait_for_orientation_changes() that would previously
always have timed out was in
meta_test_orientation_manager_has_accelerometer(), which does not
actually expect to see an orientation-changed signal. Make this wait
for the accelerometer to be detected instead.

When we use gbm together with the NVIDIA driver, we want the EGL/Vulkan
clients to do the same, instead of using the EGLStream paths. To achieve
that, make sure to only initialize the EGLStream controller when we
didn't end up using gbm as the renderer backend.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2052>
This switches the order of what renderer mode is tried first, so that
the gbm renderer mode is preferred on an NVIDIA driver where it is
supported.
We fall back to still try the EGLDevice renderer mode if the created gbm
renderer is not hardware accelerated.
The last fallback is still to use the gbm renderer, even if it is not
hardware accelerated, as this is needed when hardware acceleration isn't
available at all. The original reason for the old order was due to the
fact that a gbm renderer without hardware acceleration would succeed
even on NVIDIA driver that didn't support gbm.

This replaces functionality that MetaRenderDevice and friends has
learned, e.g. buffer allocation, EGLDisplay creation, with the usage of
those helper objects. The main objective is to shrink
meta-renderer-native.c and by extension meta-onscreen-native.c, moving
its functionality into more isolated objects.

All render devices that have a device file backing them might be able to
allocate dumb buffers, so add a helper for doing that. Will indirectly
result in an error up front on a surfaceless render device due to lack
of a device file.

It might not be needed by the user of the buffer, so don't always
require it up front. Instead make sure that any user that needs it first
calls "meta_drm_buffer_ensure_fb_id()" to create the ID.
Only the plain gbm implementation creates the ID lazilly, the other
still does it on construction due to the objects used to create them
only existing during construction.

Mostly calls into gbm_bo_* API, or something somewhat similar when on
dumb buffers. Added API are:
* get offset for plane
* get bpp (bits per pixel)
* get modifier
This will allow users of MetaDrmBuffer to avoid having to "extract" the
gbm_bo to get these metadata.

The purpose of MetaRenderDevice is to contain the logics related to a
render device; i.e. e.g. a gbm_device, or an EGLDevice. It's meant to
help abstract away unrelated details from where it's eventually used,
which will be by MetaRendererNative and the MetaOnscreenNative
instances.

Meant for MetaRenderer and everything related that deals with turning
composited frames, or client buffers, into mode set updates. This is
slightly related to the debug topic 'kms' is meant for the KMS details.

It was a feature relevant for when Clutter was an application toolkit
that wanted the application window to communicate a minimum size to the
windowing system.
Now, clutter is part of the windowing system component, so this feature
doesn't make any sense, so remove it.

This feature was configured depending on whether the Cogl backend
reported COGL_WINSYS_FEATURE_MULTIPLE_ONSCREEN or not. All cogl backends
do report this, so any code handled the 'static' case were never used.
While we only ever use one stage, it's arguable more correct to
consilidate on the single stage case, but multiple stages is something
that might be desirable for e.g. a remote lock screen, so lets keep this
logic intact.
This has the side effect of completely removing backend features, as
this was the only left-over feature detection that they handled.
