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.

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.

The work at https://gitlab.gnome.org/GNOME/gnome-control-center/issues/239
intended to make integrated devices optionally mappable to other outputs
(in order to allow fix mishandling from our heuristics, or to quickly reach
things in other monitor without changing devices).
This was missed in that plan, we do allow cycling outputs, but we still did
prevent it from doing anything for integrated devices. Fix that, and change
output cycling so we don't allow a "NULL" EDID for integrated devices, this
makes those go through the MetaInputMapper (resulting in one output listed
twice), instead of mapping to the full stage.

The cursor tracker may give us a valid position, and a
valid cursor sprite, and yet the cursor can be hidden,
meaning we must hide the cursor on the stream as well.
Remove cursor from stream buffer if it's hidden.

Scanouts are taken away after painting. However, when we're
streaming, what we actually want is to capture whatever is
going to end up on screen - and that includes the scanout
if there's any.
Add a before-paint watch that only records new frames if a
scanout is set.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1421
When there's a direct scanout set in the stage view, we
have to use it instead of the view's regular onscreen
framebuffer.
Use the new CoglScanout API to implement blitting to the
stream framebuffer.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1421
This will be used when screencasting monitors so that if
there's scanout in place, it'll still be possible to blit
it to a PipeWire-owned framebuffer, and stream it.
Add a new 'blit_to_framebuffer' vfunc to CoglScanout, and
implement it in MetaDrmBufferGbm.

Just because X11/XI uses a particular terminology doesn't mean we
have to use the same terms in our own API. The replacement terms
are in line with gtk@1c856a208, which seems a better precedent
for consistency.
Follow-up to commit 17417a82a5.

QXL doesn't support mmap():ing a DMA buffer allocated in mutter inside
the PipeWire stream consumer process. To make screen casting work again
on QXL, disable DMA buffer based screen casting for QXL.
Eventually, it should be the client that renegotiates the supported
buffer types, but until then we need this list.

The X server, including Xwayland, can be compiled with different X11
extensions enabled at build time.
When an X11 extension is built in the X server, it's usually also
enabled at run time. Users can chose to disable those extensions at run
time using the X server command line option "-extension".
However, in the case of Xwayland, it is spawned automatically by the
Wayland compositor, and the command line options are not configurable
by users.
Add a new setting to disable a selected set of X extension in Xwayland
at startup, without needing to rebuild Xwayland.
Of course, if Xwayland is not built with a given extension support in
the first place (which is the default for the security extension for
example), that option has no effect.

Delay the addition and removal of devices using ClutterDeviceEvent's so that
they are processed following the libinput event order, and that we don't
have to flush the events on removal.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1371
When a device is removed from the seat the events that this device may have
emitted just before being removed might still be in the stage events queue,
this may lead a to a crash because:
Once the device is removed, we dispose it and the staling event is
kept in queue and sent for processing at next loop.
During event processing we ask the backend to update the last device
with the disposed device
The device is disposed once the events referencing it, are free'd
The actual last device emission happens in an idle, but at this point
the device may have been free'd, and in any case will be still disposed
and so not providing useful informations.
To avoid this, once a device has been added/removed from the seat, we queue
ClutterDeviceEvent events to inform the stack that the device state has
changed, preserving the order with the other actual generated device events.
In this way it can't happen that we emit another event before that the
device has been added or after that it has been removed.
Fixes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1345
When removing a device that has been just marked as the last in use, we may
try to notify that a NULL device is the last one.
This is not supported, as both update_last_device() and the clients of the
"::last-device-changed" signal are assuming that the last device is always
a valid ClutterInputDevice.
So let's avoid erroring, and stop the idle when clearing the current device.

PipeWire reuses buffers, and buffer metadatas, when streaming. When
the cursor is moved to outside the stream, the cursor meta also needs
to be updated, otherwise it'll use the cursor position of whatever is
in the buffer.
Don't bail out when cursor is outside the stream, and ensure to record
a metadata-only frame. This only applies to metadata streams.
