5e67e35ec5 compositor: Setup and use ownership chains
As with the backend commit, this means all objects can reach the
MetaContext by walking up the chain, thus can e.g. get the backend from
the context, instead of the global singleton.

This also is a squashed commit containing:

compositor: Get backend via the context

The MetaCompositor instance is owned by MetaDisplay, which is owned by
MetaContext. Get the backend via that chain of ownership.

dnd: Don't get backend from singleton

window-actor: Don't get backend from singleton

dnd: Don't get Wayland compositor via singleton

background: Don't get the monitor manager from the singleton

plugins: Don't get backend from singleton

This applies to MetaPlugin, it's manager class, and the default plugin.

feedback-actor: Pass a compositor pointer when constructing

This allows getting to the display.

later: Keep a pointer to the manager object

This allows using the non-singleton API in idle callbacks.

c390f70edc backend: Set up and use ownership chains
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

fc8a4afc45 Remove meta_is_stage_views_enabled()
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.

58c3734d78 backend/native: Prepare render devices earlier than KMS
The type of render device used for a specific GPU affects the mode
setting backend that can be used, more specifically, when the render
device is an EGLStream based one, atomic mode setting isn't possible, as
page flipping is done via EGL, not via atomic mode setting commits.

Preparing the render devices before KMS devices means can make a more
informed decision whether to deny-list atomic mode setting for when
a certain GPU uses a EGLStream based render device instance.

This also means we need to translate mode setting devices to render node
devices when creating the render device itself, as doing it later when
creating the mode setting device is already too late.

0debb24e12 barriers: Make barriers fully part of the backend
Prior to this commit, barriers were created with a MetaDisplay pointer,
despite being entities related and owned by the backend. In the X11
case, it was also not hooked up to the backend X11 connection, but the
clutter one, meaning for example that the logic was active (but dormant)
also for the Xwayland connection.

Fix this by moving X11 barrier management and event processing fully to
the backend. Also replace passing a display pointer with passing a
backend pointer. Keep the display pointer around for a release, but mark
it as deprecated.

09538422c6 backends: Update idle time after opening the lid
When handling lid state, we used to update the idle time right after
opening the lid. This behavior changed in commit 14b6c8780d due
to a typo/thinko, "if (lid_is_closed)" used to be an early return
condition before updating idle time, now it only updates in that
case.

Restore the original behavior, since this idle time update is key
in having gsd-power light up the display again, this presumably
fixes situations that required extra "light up" hints after suspend.
What it does surely fix is "ninja test" in g-s-d against recent
mutter, since the behavioral change induced a test timeout there.

8008f0b7b0 Explicitly create the clutter context and backend
This changes the setup phase of clutter to not be result of calling an
init function that sets up a few global singletons, via global singleton
setup vfuncs.

The way it worked was that mutter first did some initial setup
(connecting to the X11 server), then set a "custom backend" setup vfunc
global, before calling clutter_init().

During the clutter_init() call, the context and backend was setup by
calling the global singleton getters, which implicitly created the
backend and context on-demand.

This has now changed to mutter explicitly creating a `ClutterContext`
(which is actually a `ClutterMainContext`, but with the name shortened to
be consistent with `CoglContext` and `MetaContext`), calling it with a
backend constructor vfunc and user data pointer.

This function now explicitly creates the backend, without having to go
via the previously set global vfunc.

This changes the behavior of some "get_default()" like functions, which
will now fail if called after mutter has shut down, as when it does so,
it now destroys the backends and contexts, not only its own, but the
clutter ones too.

The "ownership" of the clutter backend is also moved to
`ClutterContext`, and MetaBackend is changed to fetch it via the clutter
context.

This also removed the unused option parsing that existed in clutter.

In some places, NULL checks for fetching the clutter context, or
backend, and fetching the cogl context from the clutter backend, had to
be added.

The reason for this is that some code that handles EGL contexts attempts
to restore the cogl EGL context tracking so that the right EGL context
is used by cogl the next time. This makes no sense to do before Cogl and
Clutter are even initialized, which was the case. It wasn't noticed
because the relevant singletons were initialized on demand via their
"getters".

c789b6be38 backend: Reset idletime when unplugging the power cable
Avoid having laptops suspend or lock as soon as the power cable is
unplugged as the timeout for those actions when on battery are smaller
than the timeouts when on AC.

- laptop is plugged in, and hasn't been used for X minutes
- laptop is unplugged
- the gnome-settings-daemon power plugin sets up its timeouts for
  inactivity for the "on battery" case
- those X minutes of inactivity are still counting, and are above
  the level of one of the timeouts (say, suspend or lock screen),
  mutter fires the timeouts
- gsd-power activates the action associated with the timeout

012c0a18ef clutter: Ensure we always call handle_event_post for processed events
Since commit 2ceac4a device-related X11 events aren't processed anymore,
causing the input settings not to handle the devices.
This is due to the fact that we may never call clutter_seat_handle_event_post()
for such events.

While this is always happening for the native backend, it doesn't happen in
X11 because the events are removed from the queue as part of
meta_x11_handle_event(), and thus no event was queued to the stage by the
backend events source.

This also makes sure that the event post handler is called after the
event is actually processed, and not before an event is queued.
