PipeWire recently introduced busy buffers, which actually fixes the last remaining

cogl_framebuffer_flush() ones.
Switch to cogl_framebuffer_flush() in all three stream sources.

When a transfer request is done to the MetaSelectionSourceRemote source,
it's translated to a SelectionTransfer signal, which the remote desktop
server is supposed to respond to with SelectionWrite.
A timeout (set to 15 seconds) is added to handle too long timeouts,
which cancels the transfer request.

The original implementation of ::touch-mode tested for keyboard
presence to know whether the OSK and other touch-only features were
enabled.
However that didn't pan out, every webcam, card reader and kitchen
sink like to live a second life as EV_KEY devices. This made the
detection of actual external keyboards a much harder task than it
sounds, and was thus removed in commit f8e2234ce5.
Try a different approach here, and test for pointer devices, it
doesn't matter if internal or external devices, the rationales:
- It is significantly easier to get this right, there's virtually
no devices with abs/rel axes that don't try to be a real input
device of some sorts.
- It's not as good as testing for keyboard presence, but it's the
next best thing. These usually come in pairs, except in weird
setups.
- It is better than not having anything for a number of situations:
- Non-convertible laptops with a touchscreen will get touch-mode
disabled due to touchpad presence (plus keyboard). There's
been complains about OSK triggering with those.
- Same for desktop machines with USB touchscreens, the mouse
(and presumably keyboard) attached would make touch-mode
get in the middle.
- Convertible laptops with a broken tablet-mode switch get a
chance to work on tablet modes that do disable input devices
(e.g. detachable keyboards, or via firmware)
- Kiosk machines, tablets, and other devices that have a
touchscreen but will not regularly have a mouse/keyboard
will get the touch-mode enabled.
All in all, this seems to cover more situations the way we expect it,
there's only one situation that the OSK would show where it might
not be desirable, and one that might not show when it better should:
- Tablets and kiosk machines that get one keyboard plugged, but not a
mouse, will still show the OSK, despite being able to type right
away.
- Convertible laptops with broken/unreliable tablet-mode switch (e.g.
ignored by the kernel) rely entirely on the device/firmware
characteristics to work. If after folding into tablet mode the
touchpad remains active, touch-mode will not turn on.
Fixing the tablet-mode switch on these devices should be preferred,
as that'll also make libinput magically disable the touchpad.
The latter can be worked around with the a11y toggle. The former is
merely inconvenient, and nothing prevents the user from plugging a mouse
in addition.

Mutter freezes Xwayland commits when resizing windows, and thaw them in
the window actors' after_paint() for X11.
Yet, after_paint() could be never called, as when a new window is mapped
while the overview is active in gnome-shell.
As a result, the content of the X11 window will remain invisible to the
overview.
Add a new window actor API to tell whether commits can be frozen. For
Wayland window actors, this always return FALSE, whereas for X11 window
actors, it checks whether the Clutter actor is mapped.

When (un)maximizing, (un)fullscreening, the move/resize action is
flagged with 'ACTION_MOVE' and 'ACTION_RESIZE' , while e.g.
'appears-focus' does not.
When a client misbehaved and didn't immediately reply to a configure
request with a commit with the corresponding ack_configure, the
following commit would trigger a oddly timed move, making the window
appear to move back to a previous position.
Avoid this issue by only carrying over the target window position if the
configuration actually contained a new position.
We cannot only rely on the flags however, as e.g. a new position should
be respected during interactive resize, even though only 'ACTION_RESIZE'
is passed in such scenarios.
Do the same for the size, except if the window state dictates that the
size is fixed to a certain size, e.g. being fullscreen or maximized.

Mutter needs to fetch the X11 Window ID from the onscreen and did that
by using an X11 specific API on the CoglOnscreen, where the X11 type was
"expanded" (Window -> uint32_t). Change this by introducing an interface
called CoglX11Onscreen, implemented by both the Xlib and GLX onscreen
implementations, that keeps the right type (Window), while avoiding X11
specific API for CoglOnscreen.

Thins means that e.g. MetaOnscreenNative now inherits CoglOnscreenEgl,
which inherits CoglOnscreen which inherits CoglFramebuffer, all being
the same GObject instance.
This makes it necessary to the one creating the onscreen to know what it
wants to create. For the X11 backend, the type of renderer (Xlib EGL or
GLX) determines the type, and for the native backend, it's currently
always MetaOnscreenNative.

Previously the wl_resource and MetaWaylandGtkSurface corresponding to
any client gtk_surface have been kept around until the exit of the
client due to the client side destroy method not signaling the
destruction to the server. Ideally the protocol would have specified a
destroy request marked as destructor to handle this automatically,
however this is no longer possible due to the destroy method being
implicitly generated in the absence of an explicit request in the
protocol. Adding a destroy request marked as destructor now would
generate a new destroy method that unconditionally would send the
request to the server, which would break clients running on servers not
supporting that request.
So instead of modifying the destroy request add a new "release"
destructor, that indicates to the server that it can release the
resource. This can be optionally be used by clients depending on the
server protocol version.

The MetaWaylandSurface corresponding to a MetaWaylandGtkSurface can be
destroyed before the MetaWaylandGtkSurface is destroyed. In its destroy
function MetaWaylandSurface however was unsetting the destructor of the
correspnding resource along with the gtk_surface1 interface
implementation. This was done to prevent further gtk_surface1 requests
on a NULLed MetaWaylandSurface, if it has been destroyed before the
MetaWaylandGtkSurface.
It would be enough to just unset the resource implementation, while
keeping the destructor to fix this leak. However the following commit
will rely on the implementation being available after the
MetaWaylandSurface has been destroyed. So instead introduce NULL checks
for all functions that can be called on the gtk_surface1 interface and
do not unset the implementation.

Fullscreen X11 windows that attempt to change the resolution on Wayland
use a surface viewport to achieve this without affecting the resolution
of the display. This however also means that pointer events will be
delivered in the display coordinates while the code handling the window
frame is not aware of any such viewport scaling. So a right click
outside of the area corresponding to the new resolution will not be
considered to be on the client area. And since the only area that is
ignored when determining whether to perform the right click action, such
as opening the context menu, is the client area, this will result in the
action being performed, despite happening on the (scaled) client area.
While it would be possible to scale the event coordinates so that
get_control() correctly determines the frame element the cursor is on,
viewport scaling only affects fullscreen windows. Since fullscreen
windows have no frame, we can always assume that if the window gets
delivered an event for a fullscreen window, it is on the client area
without doing any additional calculations.

This adds a MetaKmsImplDevice backend using atomic drmMode* API in constrast to
non-atomic legacy drmMode* API used in MetaKmsImplDeviceSimple.
This has various behavioral differences worth noting, compared to the
simple backend:
* We can only commit once per CRTC per page flip.
This means that we can only update the cursor plane once. If a primary
plane composition missed a dead line, we cannot commit only a cursor
update that would be presented earlier.
* Partial success is not possible with the atomic backend.
Cursor planes may fail with the simple backend. This is not the case
with the atomic backend. This will instead later be handled using API
specific to the atomic backend, that will effectively translate into
TEST_ONLY commits.
For testing and debugging purposes, the environment variable
MUTTER_DEBUG_ENABLE_ATOMIC_KMS can be set to either 1 or 0 to
force-enable or force-disable atomic mode setting. Setting it to some
other value will cause mutter to abort().

In order to reliably manage the reference count of the user data passed
to page flip listeners - being the stage view - make the ownership of
this data travel through the different objects that take responsibility
of the next step.
Initially this is the MetaKmsPageFlipListener that belongs to a
MetaKmsUpdate.
When a page flip is successfully queued, the ownership is transferred to
a MetaKmsPageFlipClosure that is part of a MetaKmsPageFlipData. In the
simple impl device, the MetaKmsPageFlipData is passed to
drmModePageFlip(), then returned back via the DRM event. In the future
atomic impl device, the MetaKmsPageFlipData is stored in a table, then
retrieved when DRM event are handled.
When the DRM events are handled, the page flip listener's interface
callbacks are invoked, and after that, the user data is freed using the
passed GDestroyNotify function, in the main context, the same as where
the interface callbacks were called.
When a page flip fails, the ownership is also transferred to a
MetaKmsPageFlipClosure that is part of a MetaKmsPageFlipData. This page
flip data will be passed to the main context via a callback, where it
will discard the page flip, and free the user data using the provided
GDestroyNotify.
Note that this adds back a page flip listener type flag for telling the
KMS implementation whether to actively discard a page flip via the
interface, or just free the user data. Avoiding discarding via the
interface is needed for the direct scanout case, where we immediately
need to know the result in order to fall back to the composite pipeline
if the direct scanout failed. We do in fact also need active discard via
the interface paths, e.g. in the simple impl device when we're
asynchronously retrying a page flip, so replace the ad-hoc discard paths
in meta-renderer-native.c and replace them by not asking for no-discard
page flip error handling.

Suspending might have changed the CRTC configuration, turning some off,

Destroying an onscreen destroyes the gbm_surface, the gbm_bo's, and the
fb_id's. Doing this (drmModeRmFB() of the fb_id specifically), may on
some hw implicitly disable the CRTC of the plane that framebuffer was
assigned to. This would cause following atomic commit that attempts to
disable the CRTC to fail as disabling an already disabled CRTC is not
allowed.
It'd also mean we'd always disable the plane before having finished next
mode set, leaving it monitor content potentially empty when not really
necessary.
Solve this by keeping the CoglOnscreens (thus the gbm_surface, gbm_bo
and fb_id) alive until the following global mode set has completed, i.e.
the new state has been fully committed and applied.

This makes "power save" (i.e. when you make a monitor go into power save
mode, or make it come out of power save mode), a per device action when
turning on power saving (power save being set to 'off'), and implicitly
handled when turning off power saving (power save being set to 'on')
when doing a mode set.
This is needed as with atomic mode setting, the configuration of DPMS
(Display Power Management Signaling), is replaced by directly turning on
or off CRTCs, and via the CRTC drm properties. Thus in order to handle
both with a common API, make that API high level enough for both cases
being covered.

Before we received new gamma updates via D-Bus and posted the update to
KMS directly. This won't be possible with atomic KMS, since one can only
update the state of a CRTC once per cycle.
Thus, to handle this, when configured by D-Bus, only cache the value,
and mark it as invalid. The next frame, the native renderer will pick
up the newly cached gamma value and configure the CRTCs accordingly.

We cannot switch DPMS state to 'on' first, then mode set later, when
using atomic KMS. So when we're turning it on, just let the eventual

This will happen for example with the simple KMS impl backend will do a

Don't mode set each CRTC in separate KMS updates, as reconfiguring one
CRTC might cause other CRTCs to be implicitly reset thus as well,
causing KMS return EBUSY if using atomic modesetting.
Prepare for this by compositing each CRTC first including adding steps
to the KMS update, but wait until all views has rendered at least once
before posting the initial update. After this each CRTC is posted
separately.
Using EGLStreams instead of normal page flipping seems to fail when
doing this though, so handle that the old way for the EGLStream case,
i.e. eglSwapBuffers() -> mode set with dumb buffer -> eglStream
"acquire" (resulting in page flip under the hood).
For this we also introduce a new error code so that we don't use client
buffers when doing mode sets, which could accidentally configure the
CRTC in a way that is incompatible with the primary plane buffers.
Do the same also when we're in power save mode, to only have one special
case path for this scenario in the regular swap-buffer path.

When we e.g. try to post an direct client buffer scanout update, it

Something might want to affect the next update that is going to be

Note, the API for notifiying about results take out the result listener

list, set the actual state change, and then have the implementation
translate that into the necessary property changes.

With the aim at always using the property table to fetch and parse
property metadata, move IN_FORMATS handling to the property table, using
the newly introduced parse vfunc.

Values may need to be processed and parsed in custom ways; make this
possible via the property table infrastructure using a callback.
Will be used for e.g. parsing rotation and formats.

Instead of relatively verbosely going through the DRM properties finding
the properties we care about and saving their ID's, add a more
declarative way to fetch property metadata. This'll allow for fetching
more property IDs with relatively less code, which will be useful for
the atomic backend.
