Add meta_kms_impl_device_open_non_privileged_fd() that returns a
non-master file descriptor for a MetaKmsImplDevice.
It'll be required to implement wp_drm_lease_device_v1_send_drm_fd() in a
future commit.

The manager keeps track of which connectors are leasable in general,
which connectors and resources are already part of a lease, and keeps
track of when leases get revoked.
When leasing out connectors, the required drm resources to drive the
connectors are included in the lease as well.

When a plane is leased, it is assigned to a CRTC which is leased. When
trying to find a primary plane for a modeset, skip the assigned planes
on leased CRTCs to avoid sharing the resources with the leased process.

This allows us to keep track when primary and cursor plane assignments
on a CRTC are unassigned. With this commit, all planes which are
assigned are actually in use and can't be assigned to anything else.
We'll make use of that fact when we search for a leasable primary plane.

The lease_objects function takes connectors, CRTCs and planes which are
turned into a drm lease. The resulting lease can be revoked with
revoke_lease. With list_lessees the currently active leases can be
queried.

With leasing, we will give another client control over connectors but
they also need a CRTC to drive them. Those CRTCs won't be available to
the desktop/monitor-manager.

Add an environment variable (MUTTER_DEBUG_LEASE_CONNECTORS) that allows
set a ":" separated list of connector names as available for lease.
The names of the connectors can be found in "/sys/class/drm".
To illustrate it with an example, the names of the connectors and its
status can be fetched with this command:
$ for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n "${con#*/card?-}: "; cat $p; done
DP-1: disconnected
DP-2: disconnected
DP-3: disconnected
DP-4: disconnected
DP-5: connected
DP-6: connected
DP-7: disconnected
eDP-1: connected
HDMI-A-1: disconnected
And, to set "DP-5" and "DP-6" available for lease, the environment
variable can be set like:
MUTTER_DEBUG_LEASE_CONNECTORS=DP-5:DP-6
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3746>
This is intended to be used to filter out what connectors will be
available for lease, i.e. non-desktop ones.

When mutter creates a dma-buf buffer for screencasting, the buffers
stride will, among other attributes, also be defined.
However, mutter currently only sets the buffer stride, when actually
recording a frame, but not when adding it.
This behaviour disallows screencast consumers (clients) to already
import the respective buffer (i.e. for Vulkan creating a VkImage for the
dma-buf image), as the stride is not yet communicated to the client.
Since the stride won't change after adding the respective buffer,
directly set the buffer stride, when adding the PipeWire buffer. This
allows screencast consumers (clients) to do optimizations in their
encoding paths.

Let the ClutterFrame (or rather MetaFrameNative) own both the scanout
object and the framebuffer object, and let the frame itself live for as
long as it's needed. This allows to place fields that is related to a
single frame together, aiming to help reasoning about the lifetime of
the fields that were previously directly stored in MetaOnscreenNative.
Also take the opportunity to rename "current" to "presenting", to make
it clearer that frame's buffer is what is currently presenting to the
user.

If view initialization fails then don't add the view, rather than
adding a dummy offscreen view. This avoids flooding the log with
offscreen frame clock confusion:

When testing mutter using `META_DBUS_RUNNER_WRAPPER=rr` we may get a
not found-device error, given that it's not a case we support, we can
ignore it as we do with permission denied one, limiting this to the RR
case.

We're not doing anything significant in the KMS thread anyway, so don't

Don't try to find the card, and then the render node from it, just ask
udev to list the render nodes directly. This avoids running into
permission errors when the user cannot open /dev/dri/card* even without
mode setting capabilities.

This is structured so as to measure all timestamps first before logging

Instead use an abstract "logical monitor id" that is generated from the
logical monitor. Instead of using low level numbers from the mode
setting devices, use either data from the EDID, or the connector, if the
EDID is not useful.
This should help with windows remembering monitor positions when the
same monitor reappears but with another mode setting device ID.

We were leaking the color profile path keys but also it wasn't clear how
the ownership was passed to the new hash-table, so let's just remove it
from the pending hash table and add it to the new one including the
expected reference.
This is safe because we were still adding a temporary extra ref to the
profile

For a Wayland only build, we would like to avoid linking against
libXcursor which on it turn, links back to some of the X11 deps.
In order to achieve that, we include a small subset of xcursor.
In case Mutter is built with X11 or with both Wayland & X11, we link
against libXcursor and don't make use of the in-tree implementation.
This patch mimics what GTK 4 do by shipping an in-tree copy of xcursor.
Especially that libwayland-cursor does not provide an alternative to
xcursor itself.

In case of empty regions (e.g. when locking the pointer) the pointer
was only forced to stay within the boundaries of its current pixel
(i.e. culling subpixel position), instead of the position where the
pointer lock did start.

Since 07d24fe50 regions are not translated to their on-screen
coordinates anymore, but are relative to the origin stored in the
constraint. This origin however was not considered when checking whether
the pointer was within the constraint region. This meant that the
constraint region would appear to always be placed at 0,0 instead of on
the surface.
Fix this by using the cursor position relative to the origin.
