This is done from the backend X11 connection, but needs directing at times
from the frontend X11 connection. Commit 5a8509f89503 added a XEvent
argument presumably for possible future expansions that did never come.
Since this function is nothing about events, drop the XEvent argument and
make the name a little bit more ad-hoc (according to what it does, at
least).

Despite the attempt to make this a generic interface, this was
pretty much used only by the X11 backend, and now it ported away
from it.
This now stands unused and may be removed, in favor of backends
each creating and injecting events as they please.

This is about the only reason now to go through the ClutterBackend
translate_event vmethod. We can do that directly, and stop requiring the
generic vmethod that is actually just used for X11 events.

There's no need for an XEvent filter, since this is already code close enough
to MetaBackendX11 XEvent handling and always required anyways. Make the a11y
configuration checks happen directly from MetaBackendX11 event handling.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3153>
We are pretty much guaranteed that the first event will be handled after
the cogl renderer has been set up. We can avoid the loop through
ClutterBackend vmethods and X11 event filters, and call this directly
from the code that is already close to the MetaClutterBackendX11.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3153>
It is a bit backwards that events contain information about
the stage they are being handled by. It makes more sense to
specify in the ClutterEvent handling entrypoint the stage
that will handle the event.
As a first step, add this ClutterStage argument, even though
the information is still carried through the event in order to
keep satisfying calls to the getter function.
This entrypoint has been also renamed to clutter_stage_handle_event(),
so that its ownership/namespace is clearer.

This allows for a sticky barrier to hold the pointer until it is
released, but the owner of the barrier doesn't need a barrier event to
release it. It will be used to implement input capturing.

This is different from "warping" as it doesn't necessarily result in a
pointer motion event. This can be helpful during initializing so we can
avoid faked pointer events that would otherwise need to be special cased
to not appear as actual pointer movements.

This is missed, leaving the cursor renderer disconnected from the stage
updates that could trigger further frame callbacks on the cursor, leaving
some clients like Xwayland stuck with cursors.

While it's obviously good to trap possible errors from X calls, we are
mixing the Clutter error trap with the MetaX11Display one for these
calls.
This may result in situations where a X call within a Clutter error
trap fails, but it's actually handled in these sections using the
MetaX11Display error trap. This one will consider the serial out
of the "handled" parts and raise an error.
It is better to stay consistent here, and use the same error traps
than the rest of the X11 backend.

Since c390f70edca40d ("backend: Set up and use ownership chains")
the type of the ClutterInputDevice object's "meta-input-settings-xdevice"
data is `DeviceHandle`, but that commit failed to change the one place
where the object data is queried. As a consequence, that part still
considers it to be an `XDevice`, so everything that uses the return
value of `device_ensure_xdevice()` works with invalid data. Furthermore,
`device_handle_free()` incorrectly uses the `user_data` as the argument
for `XCloseDevice()` leading to a double free.

Returning FALSE does not indicate an error, but a valid backlight
value of 0. Consumers expect a negative value to indicate no
backlight support, so return -1 in case of error, just like we
already do for invalid values.

This means objects have an owner, where the chain eventually always
leads to a MetaContext. This also means that all objects can find their
way to other object instances via the chain, instead of scattered global
singletons.
This is a squashed commit originally containing the following:
cursor-tracker: Don't get backend from singleton
idle-manager: Don't get backend from singleton
input-device: Pass pointer to backend during construction
The backend is needed during construction to get the wacom database.
input-mapper: Pass backend when constructing
monitor: Don't get backend from singleton
monitor-manager: Get backend directly from monitor manager
remote: Get backend from manager class
For the remote desktop and screen cast implementations, replace getting
the backend from singletons with getting it via the manager classes.
launcher: Pass backend during construction
device-pool: Pass backend during construction
Instead of passing the (maybe null) launcher, pass the backend, and get
the launcher from there. That way we always have a way to some known
context from the device pool.
drm-buffer/gbm: Get backend via device pool
cursor-renderer: Get backend directly from renderer
input-device: Get backend getter
input-settings: Add backend construct property and getter
input-settings/x11: Don't get backend from singleton
renderer: Get backend from renderer itself
seat-impl: Add backend getter
seat/native: Get backend from instance struct
stage-impl: Get backend from stage impl itself
x11/xkb-a11y: Don't get backend from singleton
backend/x11/nested: Don't get Wayland compositor from singleton
crtc: Add backend property
Adding a link to the GPU isn't enough; the virtual CRTCs of virtual
monitors doesn't have one.
cursor-tracker: Don't get display from singleton
remote: Don't get display from singleton
seat: Don't get display from singleton
backend/x11: Don't get display from singleton

There is no need to use the 'bypass-*' method of event processing in the
changed function since in all cases the 'bypass-*' variable was set, any
following event processing functions would ignore the event anyway.
Simplify things a bit by just returning TRUE if the event is consumed.

This is an old relic from when ClutterStageView was being added, and
tests were somewhat prepared to be able to test the "X11 style" of
things, with the nested backend some how managing to emulate that.
Lets drop that stuff, it isn't used by the test suite, and isn't useful
anyway; if we want to test X11 configurations, we should use the actual
X11 backend, which didn't make use of this anyway.

This allows using two separate ICC profiles for one "color profile",
which is necessary to properly support color transform
calibration profiles from an EFI variable.
These types of profiles are intended to be applied using the color
transformation matrix (CTM) property on the output, which makes the
presented output match sRGB. In order to avoid color profile aware
clients making the wrong assumption, we must set the profile exposed
externally to be what is the expected perceived result, i.e. sRGB, while
still applying CTM from the real ICC profile.
The separation is done by introducing a MetaColorCalibration struct,
that is filled with relevant data. For profiles coming from EFI, a
created profile is practically an sRGB one, but the calibration data
comes from EFI, while for other profiles, the calibration data and the
ICC profile itself come from the same source.

Instead of passing 4 arguments (red, green and blue arrays as well as a
size), always pass them together in a new struct MetaGammaLut. Makes
things slightly less tedious.
The KMS layer still has its own variant, but lets leave it as that for
now, to keep the KMS layer "below" the cross backend CRTC layer.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2165>
In practice, for KMS backend CRTC's, we cache the gamma in the monitor
manager instance, so that anyone asking gets the pending or up to date
value, instead of the potentially not up to date value if one queries
after gamma was scheduled to be updated, and before it was actually
updated.
While this is true, lets still move the API to the MetaCrtc type; the
backend specific implementation can still look up cached values from the
MetaMonitorManager, but for users, it becomes less cumbersome to not
have to go via the monitor manager.

Same applies to MetaOutput. The reason for this is to make it possible
to more reliably know when there was EDID telling us about these
details. This will be used for colord integration.
