Many tablets have a native portrait mode panel, yet come with a keyboard dock,
where the device gets docked in landscape mode. To avoid the display being
on its side when mutter starts while the tablet is docked, we need to take
the accelerometer reported orientation into account even if there is a
tablet-mode-switch which indicates that the device is NOT in tablet-mode
(because it is docked).
Add special handling for the first time the "orientation-changed"
signal gets signalled by the orientation-manager, which happens after it
has successfully claimed the accelerometer with iio-sensor-proxy.
The added special handling of the initial "orientation-changed" signal
does a number of checks:
1. panel_orientation_managed is false because of the tablet-mode-switch and not
because of other reasons.
2. The device has a native portrait mode panel (and thus likely needs rotation
to display the image the right way up when docked).
If all these checks succeed then it continues with creating a new
monitors-config based on the orientation ignoring the panel_orientation_managed
value (for the initial/first "orientation-changed" signal only).

The orientation reported by the orientation_manager may have changed while
panel_orientation_managed was false. So when panel_orientation_managed
changes to true we should re-check the orientation.
This fixes the orientation not being correct when e.g. taking a 360 degree
hinges 2-in-1 in clamshell mode (so landscape orientation) and then folding
it into tablet mode while holding it in portrait orientation.

Add support for the (mostly theoretical) case of an input-device
offering tablet-mode-switch functionality being unplugged.
This makes the has_tablet_switch handling identical to the has_touchscreen
handling, leading to more consistent code.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1506
Detect if a tablet-mode-switch device is already present when mutter
starts by checking for this from meta_seat_native_constructed. This
mirrors how we also set has_touchscreen from meta_seat_native_constructed.
This fixes tablet-mode-switches only being recognized when they are added
at runtime.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1506
Unconditionally setting has_touchscreen to check_touch_mode
when a new device gets added leads to has_touchscreen becoming
false when during runtime e.g. an USB keyboard gets plugged in.
Fix this by setting has_touchscreen to TRUE when check_touch_mode
is TRUE and leaving it alone otherwise.

A first step towards abandoning the CoglObject type system: convert
CoglFramebuffer, CoglOffscreen and CoglOnscreen into GObjects.
CoglFramebuffer is turned into an abstract GObject, while the two others
are currently final. The "winsys" and "platform" are still sprinkled
'void *' in the the non-abstract type instances however.

Mutter still relies heavily on singletons such as its MetaBackend.
For that, the backend implementation has a meta_init_backend() function
which is called at startup from meta_init(), which creates the desired
backend and sets the singleton which is returned by meta_get_backend().
Unfortunately, that means that the backend is never actually freed, and
all the code from the backend finalize function never actually get
called.
Add a meta_release_backend() to free the backend singleton.

The input settings constructor installs callback functions on device
added/remove and tool-changed.
However, on dispose, those signals are not disconnected, meaning that on
teardown, once the devices get removed eventually, the callback will
still fire and call the callback with freed data, causing a crash.
Make sure we clear the signals on devices on dispose, to avoid the crash
on teardown.

CoglMatrix already is a typedef to graphene_matrix_t. This commit
simply drops the CoglMatrix type, and align parameters. There is
no functional change here, it's simply a find-and-replace commit.

During seat initialization, we process early libinput events (adding all known
devices) before the seat gets a stage assigned. This causes warnings when trying
to handle the corresponding CLUTTER_DEVICE_ADDED events, as they are sent
stageless.
As it is definitely too soon to have those events sent meaningfully, filter
those events out and instead handle the CLUTTER_DEVICE_ADDED emission for all
known devices after the seat receives an stage. This makes the events guaranteed
to be emitted early in initialization, but not so soon that they can't be
handled yet.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1472
Like it's done for the pointer in other places. Without a stage assigned,
some bits (like IM handling) may end up with events ignored, and misbehave.

When a MetaBarrier is first created it allocates a backend
impl object which does the actual heavy lifting.
Unfortunately, that backend object is never freed.
This commit ensures the implementation gets freed when
the barrier object is freed.

meta_barrier_destroy is responsible for removing the extra
reference added in meta_barrier_constructed.
Unfortunately, it fails to do this because of a misplaced early
return statement.
This commit removes the spurious return.

In X, buttons 1, 2, 3 are left, middle, right. In evdev, the order is
BTN_LEFT, BTN_RIGHT, BTN_MIDDLE. So setting a scroll button to 2 gave us a
middle button in the X session and a right button in a wayland session.
Fix that by hard-coding the LMR buttons handling.

Even when a direct client buffer has a compatible format, stride and
modifier for direct scanout, drmModePageFlip() may still fail sometimes.
From testing, it has been observed that it may seemingly randomly fail
with ENOSPC, where all subsequent attempts later on the same CRTC
failing with EBUSY.
Handle this by falling back to flipping after having composited a full
frame again.

If there is no laptop panel (for example on a desktop PC or a virtual
machine), attempting to put a NULL monitor in the list of matches
will just make mapping_helper_apply() crash.

It's enabled by default when using the i915 driver, but disabled
everywhere else until it can be made reliably an improvement. Until
then, for anyone want to force-enable it, add the string
'dma-buf-screen-sharing' to the experimental features list in GSettings.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1442
Seems DMA buffer based interprocess buffer sharing is more broken than
not, so for now only enable it when using the i915 driver.
For example vmwgfx, qxl and radeon, it results in mmap() failing to mmap the
memory region. Other drivers, e.g. amdgpu will function, but may hit
very slow memory download paths, resulting in worse performance.

We only want the panel autorotation to happen if the laptop has an
accelerometer, and is in tablet mode. Regular laptop mode should
lock the orientation, and let it be configured manually.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1311
So far, we've expected this signal to not happen whenever autorotation
shouldn't apply (no accelerometer is a strong reason). In future commits
we'll add further checks to this policy, so prevent autorotation to
change the display configuration if the MetaOrientationManager signal
happens but it should be ignored.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1311
Instead of having everyone check net.hadess.SensorProxy themselves, have
this all controlled by the MetaOrientationManager, and proxied everywhere
else via a readonly property in org.gnome.Mutter.DisplayConfig.
We want to attach more complex policies here, and it seems better to
centralize the handling of the autorotation feature rather than
implementing policy changes all over the place.

We used to pick the "best" output for each builtin/size/edid categories,
and then pick the "best" (in that order) of those for each input device.
This is most often enough, but is prone to wrong results in some corner
cases (eg. 2 outputs with the exact same dimensions).
Change this to a score mechanism that doesn't leave outputs out. The
weights are the same, but the score is accumulated if an output matches
multiple categories. All outputs are evaluated and sorted by score, and
input devices with the best matches are applied first (as they already
did).
This should break the tie if eg. there's 2 outputs with similar dimensions,
but one of them has some EDID match in addition. The output with multiple
matches will score higher up, while it might have been entirely discarded
with the previous implementation.
