We'll need a few of those things from the monitor config store soon, also it's
generally useful to have a prefix which makes it clear where functions are
defined.
So factor some things out into a new monitor-config-utils.c file.

Store and load the layout mode for each logical monitor configuration in
monitors.xml by introducing a new <layoutmode> element. The value of the
element can be either "logical" or "physical". The layout mode is also
made part of the monitor configuration key.
Right now this isn't doing a lot:
When no <layoutmode> is found on the config (this is the case with all
existing configs), we'll keep using the layout mode expected by the system,
without updating the config file.
When changing an existing, or introducing a new configuration, we'll now
store the current layout mode with the config though, and load it again
on the next start of mutter. This is still not problematic as long as
mutters expected layout mode doesn't change (eg. by turning on/off
"scale-monitor-framebuffers").
When the expected layout mode of mutter switches between
restarts, the monitor config is now still loaded but remains unused,
and mutter will create (and store) a new one with the other layout mode.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596>
We'll introduce some new migration code with the next few commits to introduce
a layout_mode property in monitors.xml. This will be significantly easier
without keeping around the old monitor migration code, so drop it.

We have meta_verify_logical_monitor_config() already, and it does a few checks that
meta_verify_monitors_config() doesn't do yet, so let's also call
meta_verify_logical_monitor_config() when verifying the whole config.
We'll rely on this being part of meta_verify_monitors_config() soon, because we'll
stop calling meta_verify_logical_monitor_config() from the config parser.

We forgot to check whether multiple groups of monitors are actually
all connected with each other, so fix that.

There is one define for the format (GL_BGRA_EXT) and one for the

The first event happening for a new touch will be the CLUTTER_ENTER
event generated when picking it. Use this event for registration of
the touch info, so that MetaWaylandEventHandler.get_focus_surface may
get the right focus surface for the device/sequence on the first try.

And notably, don't cancel touch when an event handler is being
removed. Touch events are largely unaffected by most Wayland
grabs (pointer constraints, popups), so we might be cancelling
input too early if one of these wayland grabs was effective when
touch interaction began, but stopped sometime between touch updates.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3889>
Touch events are implicitly grabbed to the surface they began in,
and are not affected by the focus handler. However these events
will appear to come from the core pointer device, which might lead
to the wrong device being updated.
Ignore events with a sequence, since the default focus handler
does not intend to do anything with them.

On a hybrid machine with i915 primary and nvidia-drm (470) secondary,
`meta_render_device_egl_stream_initable_init` calls
`meta_kms_inhibit_kernel_thread` to change from the default 'kernel'
thread type to 'user'. And soon after that it would
`meta_render_device_egl_stream_finalize` because I'm not actually
using that GPU, and calls `meta_kms_uninhibit_kernel_thread`.
So during startup Mutter would default to a realtime kernel thread,
switch to a user thread (which doesn't support realtime), and then
switch back to a realtime kernel thread.
In the middle of all that, while the thread type was 'user' and
realtime disabled, something was invoking `ensure_crtc_frame` which
created a `CrtcFrame` without a deadline timer. Soon after that the
thread type changed back to 'kernel' with deadline timers expected, but
our existing `CrtcFrame` has no deadline timer associated with it. And
so it would never fire, causing the cursor to freeze whenever the primary
plane isn't changing. And the problem was permanent, not just the first
frame because each `CrtcFrame` gets repeatedly reused (maybe shouldn't
be called a "Frame"?).
Now we adapt to switching between kernel and user thread types by adding
and removing the deadline timer as required.

Colord is a system service which will result in a polkit dialog showing
up when connecting a remote session.
We want to get rid of colord eventually anyway, so disconnecting virtual
monitors from colord isn't an issue.

If we finish compositing in time, the composited result will be
submitted prior to the deadline timer is triggered, and we'll be fine,
and if not, at least the cursor updates will be smooth, which makes it
appear smoother than not.
There is a risk that this can negatively impact composited updates when
moving the cursor, so make it possible to toggle a paint-debug flag for
now until this has been more tested.
This also mean we need to disarm the deadline timer after handling
update, as there might be a scheduled cursor update pending, but we
already handled it, so disarm the timer.
Here is an illustration of the difference.
In the following scenario, with disarming, the composited frame E, and
the cursor movement C gets presented. With this branch, only the cursor
movement C gets presented.
```
* A: beginning of composited frame
* B: begin notification reaches KMS thread
* C: cursor moved
* D: calculated deadline dispatch time (disabled with the branch)
* E: KMS update posted
* F: KMS update reaches KMS thread
* G: actual deadline (and with branch and gets committed)
Compositor thread: --------A---------------E---------
\ \
\ \
KMS thread: -----------B------C----D---F-G----
```
In the following scenario, by not disarming, the cursor update C will be
presented, and the would-be-delayed composited frame E would be delayed
anyway, i.e. fixing cursor stutter.
```
* A: beginning of composited frame
* B: begin notification reaches KMS thread
* C: cursor moved
* D: calculated deadline dispatch time (and with branch will be dispatched)
* E: KMS update posted
* F: actual deadline
* G: KMS update reaches KMS thread (and with branch gets postponed)
Compositor thread: --------A---------------E---------

KMS thread: -----------B------C----D-F-G------

Although we track updates for EGL_DEVICE, they are often empty because
the primary plane has a custom page flip method. That means there's
no CRTC latched yet, but we do know exactly which CRTC is associated
with the flip. Set it so the update can still be processed.

If other handlers (e.g. DnD) are on top of the popup grab focus, we
may want it to move outside same-client surfaces as the popup grab
specifies.
Check that it is the current handler before making same-client checks,
so that these handlers on top have an opportunity to find other
surfaces, e.g. during DnD from a popup.

Move away from tracking presses/releases directly, since there might be
other event handlers on top that might prevent the popup event handler
to fully track all events. The replacement is using event state modifiers,
which will use information set from the backend, and is enough to determine
there's no more pressed buttons without tracking prior event history.
This makes the popup event handler able to interact with other event
handlers that might be on top, and consume button release events for
themselves (e.g. DnD), no longer resulting in a stuck popup grab.

As in the protocol definition for wp_drm_lease_connector_v1::withdrawn:
Sent to indicate that the compositor will no longer honor requests

Withdrawn the leased connectors and, if they are available once the
lease finishes, advertise them again.

And stop passing in the color states from the RendererNative. We also
keep the color states updated by listening for changes in the color
device.
The RendererX11Cm has a single view and no mapping to a specific color
device, so we handle the absense of a color device as well and rely on
ClutterStageView to have the default color states.

This allows us to destroy and create a new offscreen dynamically, when
the rotation or color state changes.
An idle gsource with priority higher than CLUTTER_PRIORITY_REDRAW is
used to ensure the an offscreen exists when required without having to
allocate in the redraw process.

This is usually an indication of a failed drop operation if the
