This is a step in cleaning up the Clutter context management. By making
it a GObject it's easier to add e.g. properties and features that helps
with introspection.
For now, this means the context creation is changed to go via a
"constructor" (clutter_create_context()). This is so that the global
context singleton can be mantained outsid of ClutterContext, until it
can be removed.

The intention for ClutterContext is to be more or less the MetaContext
or CoglContext equivalent. Lets rename the type so that it becomes more
consistent with the other similar types.

Group all the three config files from clutter/cogl/meta into one
and also remove unnused configurations and replace duplicated ones
This also fixes Cogl usage of HAS_X11/HAS_XLIB to match the expected
build options

This struct contains the pressed/latched/locked set of modifiers applying
to the event, and may be filled in by backends generating those events.
Other places where we forward modified key events, state may be normally
obtained from the original event.
Since this constructor is used in a variety of places, this commit
updates them all in one go.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3369>
This function may be used on key events to obtain the fully
detailed pressed/latched/locked modifiers that apply when the
event is received. No events have this detailed information
yet.
This API call may be compared to the clutter_event_get_state_full()
that existed in the past, although this getter has a stronger
predilection to it applying exclusively to key events.

This used to be the HW device that triggered the crossing (i.e.
the mouse moving the pointer, etc), or the logical device if the
crossing event happened through other means than input device
events, e.g. relayouts.
The move to ClutterEvent constructors went a bit too far in
the simplifications and broke these expectations for input-generated
crossing events.
Make this event constructor behave like the other events: receive
a source device, and figure out the corresponding logical device from
there. Also pass the source device as it'd be expected, in the
input-induced crossing event generation paths.

So far, we expected all events to have input devices set on them, IM events
lost theirs with commit 6aa42d6dad. This somewhat made sense, because IM
events are not backed by any actual device, they are generated by us in
response to eg. an OSK key press.
To fullfil the assumption that all devices at least have a logical input
device set, pass the seat to the clutter_event_im_new() constructor and then
set the device to the logical keyboard device. The source_device we leave
empty, since there is no actual physical device that this event came from.

This data is commonplace enough that it makes sense to keep it
as generic event data. Make these fields take a hard refcount, like
the private data used to do, and drop these fields from the
ClutterEventPrivate struct.

All ClutterEvent users have been changed to use getter methods
instead of direct field access. We may now make the ClutterEvent
union/structs entirely opaque by moving the definitions out of
public headers.
All future usage of ClutterEvent data should be done through
getter methods.

Move the string construction bits in the event logging happening in
MetaSeatImpl to a clutter_event_describe() call, so that it has more
freedom in fiddling with ClutterEvent internals, and may be potentially
reused in other places.

Add methods, and change the API of some rarely used methods, in order
to make all event info currently held/necessary accessible through
ClutterEvent getters, instead of direct field access.

The full decomposed modifier state is pretty much unused, relying
in keymap signals/properties to track latched modifiers state instead.
The events can be simplified without having this information, and if
it were ever needed in the future, it would be nicer that it had a
dedicated struct and didn't increase the number of arguments in
ClutterEvent constructors.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3153>
Avoid peeking in the stage for loosely related actors, since the same
event could be handled by different actors across the picking stack.
This getter is also unused, so there's wiggle room here for changes.

These constructors take all the necessary arguments to build the
event from the get go, so the callers are not left up with the task
of setting up the event struct data.

The source field was removed from ClutterEvent with commit
b644ea1bce because the preferred way of
getting the event actor is now to use the device/sequence actor from the
stage directly.
With crossing events it's not that easy though, as crossing events
explicitly have a source and related actor that doesn't have to be the
same actor as the device actor. Since we kept around the "related" field
there anyway, let's also introduce a "source" field in
ClutterCrossingEvent and return that actor when get_source() is called
on a crossing event.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2551>
We'll need the additional context of which actor the event will be
emitted to in mutters event filter (see next commit), so pass that
target actor to the event filters that are installed.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2321>
It does not make sense that the event "source" (aka the target) is
both content and recipient of a message. Not doing so, events become
largely independent of the actor that is receiving/handling an
event. This is small step toward making events opaque and immutable.
Every user of these API calls in our code have ported away from
them, but other users may remain in extensions, so make these
functions work on top of the alternative API without accessing the
soon to be removed event field.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2311>
This does two things to frown upon:
- Modifies ClutterEvent structs, while the effort is to have those
completely opaque, and readonly after creation from the input
thread side.
- Stores state in the ClutterInputDevice struct, event though those
are also considered static after creation, managed by the input
thread, etc.
Stop doing that. This makes all events just forwarded as-is in
the ClutterStage/clutter-main.c code.
Handling of click count sounds like material for a ClutterGestureAction
(or perhaps ClutterClickAction), all of both callers now do it in place
at the moment, while gestures lack a better state tracking and management.

Instead of using native backend platform data specifically, store
this info in ClutterMotionEvent. This includes time in usec since
it's just used for motion events, in the future it could make sense
to make these general to all events again, but it could make sense
to make ClutterEvent structs private before.
In order to express that a motion event has relative motion info,
the CLUTTER_EVENT_FLAG_RELATIVE_MOTION event flag has been added
for it.

We had code in both backends that sort of independently associated
sequences to slots. Make both transform slots to sequences the same
way, so they may share the implementation convert those back to slots.
This helper now lives in Clutter API.

We have this as platform-dependent data in the native backend, and
a bunch of fallback code done in place in the evcode users. Stop
making this platform-dependent data, and move it to the relevant
ClutterEvents.
The fallback code for the X11 backend case is about the same, but
now it is done directly by the X11 backend.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1623>
Making this an event is overly convoluted, accounting that we
emit the event, then convert it to a ClutterStage signal, then
its only consumer (a11y) sets the active ATK state.
Take the event out of the equation, unify activation/deactivation
of the stage in MetaStage, and use it from the X11 backend too.
