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.

It seems only the iconcache used to use it, but this is gone since
commit d16ddc42ce.
Even before that, the Xrender usage was removed in commit 556e7694de,
albeit leaving a redundant include <X11/extensions/Xrender.h> in its
place then, which comes from libXrender.

This implements the explicit sync protocol linux-drm-syncobj-v1. This
works by importing a DRM syncobj timeline and importing/exporting fds
to/from the sync points on the timeline corresponding to buffer acquire
and release. We take fds for sync points provided during a surface
commit and use them to delay transaction application, and fetch fds
from Cogl to signal when we are done using a particular buffer.

This adds the explicit sync wayland protocol to the list of build
dependencies.
This adds a copy of the linux-drm-syncobj protocol that we will use
privately for builds. This avoids the pain of requiring wayland-protocols
1.34 for distros. This commit can be reverted once we want to use
linux-drm-syncobj from the system wayland-protocols.

We depend on Gio for many introspection features (GSettings, GFile...)
without this we'd end up not having many symbols being exposed.
And errors such as
Warning: Meta: meta_display_add_keybinding: argument settings:
Unresolved type: 'GSettings*'
As per previous commit we now have this dependency implicitly, but still
it's better to make it clearer in case Clutter would drop it.

MetaWaylandInput is an object that will become in charge of handling
input events on their way to the Wayland socket. It keeps a stack
of event handlers, and propagates events and changes across them in
order to have them emit Wayland events, or change focus.
Each of these event handlers has a MetaWaylandEventInterface, this
is a vtable meant to replace MetaWaylandPointerGrabInterface and
MetaWaylandKeyboardGrabInterface in an unified manner, with the
following methods:
- get_focus_surface: to return the focus surface for a device/sequence.
Since several handlers will want to delegate logic on previous
handlers, it is optional to chain up with
meta_wayland_event_handler_chain_up_get_focus_surface().
- focus: To trigger a focus change for a device/sequence, since
event handlers are daisy chained by default, it is mandatory to
chain up with meta_wayland_event_handler_chain_up_focus(), either
with the given surface, or passing NULL to let later handlers
unset their state.
- press/motion/release: Unified handlers for pointer/touch/stylus
input, they chain up like event handlers do.
- key: Key event handler, propagates like event handlers do.
- other: Fallthrough for other events (pad, scroll, ...), propagates
like event handlers do.
Since there is a variety of expected behaviors, and the possibility
of stacking for some of the existing Wayland "grabs", this provides
the mechanism for that to happen.

In various public APIs, Clutter used to return a PangoDirection
while we have a text direction enum defined in Clutter.
This allows us to drop pango dependency from meta making it specific
to cogl-pango & clutter

The ClutterBezier code was removed in
580d62b9b clutter: Remove unused Path related types

tablet tool pressure curve calculation though so let's move it
to the native backend and rename it to MetaBezier in the process.

The debug controller can optionally, when passing --debug-control,
enable manipulating debug state, so far enabling/disabling HDR, via
D-Bus.
It's always created, in order to have a place to store debug state and
emit signals etc when it changes, but so far, it doesn't have its own
state it tracks, it just mirrors that of the monitor manager.

Currently, json-glib is used for two things:
- For loading scripts, nothing seems to use that in real life other
than some tests
- For debugging paint nodes
For now, the PR drops the first use case and only require json-glib
if it is a debug build

A MetaEisViewport represents an absolute region backend by e.g. a
pointer device. There are two kinds: a standalone viewport, which
corresponds to a viewport that has no neighbours, and a non-standalone,
which represents a region of a global coordinate space.
The reason for having non-standalone viewports is to allow to mirror the
logical monitor layout of a desktop, while the standalone are meant to
represent things that are not part of the logical monitor layout.

The 'suspend state' is meant to track whether a window is likely to be
visible any time soon. The hueristics for this are as follows:
* If a window is hidden, it will enter the 'hidden' state.
* If a window is visible, and unobscured, it will enter the 'active'
state.
* If a window is visible, but obscured by another window, it will enter
the 'hidden' state.
* If there is a mapped clone of a window, it will enter the 'active'
state.
* If the window has been in the 'hidden' state for 3 seconds, it will
enter the 'suspended' state.
This will eventually be communicated to Wayland clients so that they can
change their behaviour to e.g. save power.

In future commits, we want to be able to handle more complex textures,
such as video frames which are encoded in a YUV-pixel format and have
multiple planes (which each map to a separate texture).
To accomplish this, we introduce a new object `MetaMultiTexture`: this
object can deal with more complex formats by handling multiple
`CoglTexture`s.
It supports shaders for pixel format conversion from YUV to RGBA, as
well as blending. While custom bleding is currently only required for
YUV formats, we also implement it for RGB ones. This allows us to
simplify code in other places and will be needed in the future once
we want to support blending between different color spaces.

1. Move into the new 'common' folder and build for Wayland as well
so we will be able to share the code in follow-up commits.
2. Rename to cogl-drm-formats to make it more obvious that the format
map is more than an utility these days.
3. Drop the unused CoglTextureComponents part (see also previous
commit).
4. Move the map to the header, simplifying some future use-cases.
5. Sync formats with MetaWaylandBuffer and MetaWaylandDmaBufBuffer and
also use newly introduced opaque formats where appropriate.
This avoids duplicated code, ensures that new drm-formats added to
the dmabuf protocol have an adequate representation in Cogl from which
information like alpha support can be easily derived and finally
ensures we don't crash if the mappings got out of sync.
6. Remove some likely untested formats. In case some of these are
actually needed on certain hardware, we can test whether we got
the correct mapping by also adding support for the corresponding
wl_shm_format in MetaWaylandBuffer by extending the gradient test in

This new manager object intends to take over management of the cursor
plane from the native cursor renderer. It's API is intended to be used
from the main thread, except for the _in_input() function, but mainly
operates in the KMS context, i.e. the KMS thread.
It makes use of an "update filter" that is called before each
MetaKmsUpdate is turned into a atomic KMS commit or a set of legacy
drmMode*() API calls. When the cursor position has been invalidated,
it'll assign the cursor plane in the filter callback, using an as up to
date as possible pointer position as the source for the cursor plane
position.
Cursor updates from the input thread schedules updates for the affected
CRTCs which will cause the filter to be run, potentially for cursor-only
commits.

It currently does exactly what MetaKms and MetaKmsImpl did regarding the
context separation, which is to isolate what may eventually run on a KMS
thread into a separate unit. It works somewhat like a "user thread",
i.e. not a real thread, but will eventually learn how to spawn a
"kernel thread", but provide the same API from the outside.

This adds the actual input capturing rerouting that takes events and
first hands them to the input capture session, would it be active.
Events are right now not actually processed in any way, but will
eventually be passed to a libei client using libeis.
A key binding for allowing cancelling the capture session is added
(defaults to <Super><Shift>Escape) to avoid getting stuck in case the client
doesn't even terminate the session.
The added test case makes sure that the pointer moves again after
pressing the keybinding.

This API aims to provide a way for users to capture input devices under
certain conditions, for example when a pointer crosses a specified
barrier.
So far only part of the API is implemented, specifially the session
management as well as zone advertisement, where a zone refers to a
region in the compositor which edges will eventually be made available
for barrier placement.
So far the remote access handle is created while the session is enable,
despite the input capturing isn't actually active yet. This will change
in the future once it can actually become active.

Do the few remaining things that GDK is doing for us:
- Open and close the X11 Display
- Set up a GSource on the Display FD to handle events
- Allocate and free the content of XGenericEventCookie,
to "unroll" the few XInput2 events that Mutter still
does handle.
And remove the GdkDisplay we've so long relied on.
