If we queued a mode set, but didn't end up compositing all frames, we'll
have pending mode sets in a hash table waiting to be applied. If we
before all monitors again try to reconfigure things we should drop the
old pending mode sets and start fresh.
We already do this when we're doing so when generating views, but when
just unsetting modes, we didn't, so fix that.

We had a function called "reset_modes()" on MetaRendererNative, but what
it expected to do was to unset all modes on all CRTCs. Despite this, it
had code to unset modes on unconfigured CRTCs, probably because it was
used for multiple things in the past.
Make this a bit easier to follow by renaming the function
"unset_modes()" and fold the function doing the unsetting into the
function itself.

Intel has started to advertise big gamma LUT sizes on some hardware
because the hardware supports segmented LUTs. This means they have a lot
more precision at certain segments then others. The uAPI can't expose
this functionality meaningfully so they chose to expose a huge number of
TAPs to sample from to their segmented LUT.
This increase in uAPI LUT size resulted in stack overflows because we
allocated the LUT on the stack. This commit moves it to the heap
instead.

1. Centralize stride calculation in one function.
2. For dmabufs query the stride instead of assuming a certain value.
3. For system memory buffers use the pixel format to calculate the
stride.
4. Stop negotiating `SPA_PARAM_BUFFERS_size` and
`SPA_PARAM_BUFFERS_stride`.
2. fixes an actual bug where we reported wrong max buffer sizes,
resulting in crashes in Gstreamer when doing area screencasts on AMD
GPUs.
The reasoning for 4. is that the values were possibly wrong for
dmabufs as the negotiation happens before we create any buffers.
Further more neither Mutter nor the common consumers required it.
The later either ignore the values (OBS), always accept (gstpipewiresrc)
them or calculate the exact same possibly wrong values (libwebrtc).

When a configuration has a fractional scale, but we're using a physical
monitor layout, we can't use the scale, but if we do, we end up with
wierd issues down the line. Just discard the config if we run into this.
Eventually we probably want to store the layout mode in the
configuration so we can handle more seamless switching between physical
and logical layout mode, but first do this.

There's two aspects from its documentation
(https://xkbcommon.org/doc/current/group__state.html#gae56031a8c1d48e7802da32f5f39f5738)
affecting us here:
1. "This function is similar to xkb_state_key_get_syms(), but intended for
users which cannot or do not want to handle the case where multiple
keysyms are returned (in which case this function is preferred)."
We are indeed in that field, and have been for a long time.
2. "This function performs Capitalization Keysym Transformations."
This is unlike the xkb_key_get_syms() function that we use, and
convenient here for parity with X11 since it behaves exactly that
way.
Fixes cases where the keysym for some keys is not properly capitalized
when caps lock is toggled, due to the output of capslock+key being
different from shift+key. An example of this is 'é' in french(azerty)
layout (bound to the '2' key). Even though shift+2 outputs '2',
capslock+é should output 'É'.

The virtual stream source with CURSOR_MODE_EMBEDDED uses
META_STAGE_WATCH_AFTER_PAINT as the callback for recording its frame. In
this stage of the paint though, there is no ClutterPaintContext anymore
(there only is a paint context during the paint, not afterwards).
The callback (actors_painted()) tries to get the redraw clip from the paint
context, and we end up with a NULL pointer crash.
We actually do still have a redraw clip at this point, so because everyone
uses the paint context to get the redraw clip anyway, just pass the redraw
clip to the stage watches directly.

When a device is added, libei does not allow adding additional regions
for that particular device, as it is already advertised to the EI
client.
As a result, mutter currently effectively only adds the first region to
a device, but not the others.
This makes input in multi monitor sessions only possible on one monitor,
as the EI client cannot look up the other regions, since they were not
advertised to it.
Fix this situation by not adding and resuming the device, when a shared
device is used.
Instead, for shared devices, always add all regions first, and then
after that, add and resume the device.

Use the previously added API to release acquired mapping ids, when the
corresponding stream is destroyed.
Otherwise, the remote desktop session would maintain a whole bunch of
unused mapping ids, as their corresponding streams are already
destroyed, but maybe not the session.
Such situation would be a remote multimonitor session, where the amount
of used virtual monitors changes multiple times during the session.

The remote desktop session currently provides a mechanism to acquire
mapping ids.
However, when they are not used anymore, they currently cannot be
removed and thus just linger around.
So, add an API to release these acquired ids.

Avoid passing the MetaSeatImpl, since it may be potentially null at
MetaSeatNative construction time. An example of this triggering issues
are mousekeys, since those work on an emulated pointer device created
indirectly after a keyboard device is added (and the right settings are
enabled) at a time that the MetaSeatImpl is still being created, so the
MetaSeatNative cannot yet have a reference to it.

These objects already have a pointer to the ClutterSeat that has a
pointer to the MetaSeatImpl in its native implementation. This data
may be considered pretty much immutable (a pointer to the seat is
held, and the native implementation will shut down the implementation
thread within ClutterSeat finalization.
Avoids some awkward code, since the MetaInputDeviceNative needs to
be aware of the Clutter object implementation and the implementation
object.

vc4's implementation of `drmModeAtomicCommit` seems to require a few
milliseconds advanced notice or else it will miss the frame deadline.
That's too high for our deadline evasion threshold which is measured
in microseconds. Let's stop trying to use deadline timers on vc4 to
avoid this conflict without having to disable atomic KMS.

Realizing a cursor will assume view related state objects are valid so
they can mark them as dirty. This assumption broke when there were a
scale changed that happened with multiple CRTCs, as we'd create view
object by view object as we realized the texture. Realizing the texture
would trigger a signal that had the handler assuming the validity of all
view objects, but if we only had gotten to the first, the second view
would not be there yet, thus we'd be doing a NULL pointer dereference.
Creating the view objects first, then handling the updating avoids this
problem by making the already done assumption valid on hotplugs.
The test case added tests exactly this series of events, and uses a
virtual monitor as a cheap trick to make the KMS CRTC based view the
first one, and an arbitrary view the second that previously had its view
object initialized too late.

It's hard to tell why turning on HDR mode failed without these log
messages. It could be missing support in the sink (EDID/DisplayID) or
missing support in the driver/display hardware (connector properties) or

GInitable initialization is failable, currently, it may fail before error
traps are initialized, but error traps would be invariably deinitialized on
finalize() of the failed object. This results in an assert hit, on top of the
original failure to initialize the backend.
The libX11 error handlers are a pure client-side construct, and not a server
request, they just need XInitThreads() called to set up the library-side locks
protecting access to the global variable. This is done beforehand already at
meta_backend_x11_init(), so initialize the error traps around that time too.

While adjusting the monitor layout of my docked laptop, mutter got a
segfault while attempting to dereference the frame_info struct. This
happened on gnome-shell 44.4-1.fc38.
cogl_onscreen_peek_head_frame_info() just forwards the call to
g_queue_peek_head() which returns NULL in the event that the queue is
empty. If finish_frame_result_feedback() is expected to always be called
with a non-empty queue there's still a bug somewhere, but regardless
this API can legitimately return NULL so it should be checked for prior
to dereferencing.

If we are making an update that only disables CRTCs, we would not
actually post it, but just drop it then post nothing, as it wasn't ever
added to the mode set update hash table. This resulted in hotplugs where
we loose the all the connectors we had, where we want to disable all
CRTCs and enable nothing, to fail to disable said CRTCs.

There can be events which don't not have source devices set on them, because
they are not backed by real hardware and rather generated by us, for example
IM events coming from the shell's OSK.
So don't assume all events have a source device in
update_pointer_visibility_from_event() and rather ignore those without one,
as we are only interested in events coming from "real hardware" here.
This fixes an issue where the mouse pointer would appear on devices without
any input from actual mice/touchpads on OSK key presses.

CLUTTER_SCROLL_SOURCE_UNKNOWN only generates continuous scroll events
and no discrete scroll events.
As a result, scrolling only works in applications, that support high
resolution scroll wheels, like GTK4 applications.
GTK3 applications, on the other hand, don't support high resolution
scroll wheel events, and such scrolling does not work in these
applications.
Fix this issue by using the scroll source CLUTTER_SCROLL_SOURCE_WHEEL.
Since commit 92a90774a4 ([0]),
CLUTTER_SCROLL_SOURCE_WHEEL generates discrete events to ensure that
scrolling in legacy applications still works.

We need to trigger a mode set when power-save changes to 'on' if it's
purely about power saving, but when they arrive as part of a hotplug
event, we'll handle all that later, in the monitors-changed handling,

If the deadline timer is disabled (like on nvidia-drm or when
`MUTTER_DEBUG_KMS_THREAD_TYPE=user`), then we need to call
`meta_kms_device_set_needs_flush` on every cursor movement. But some were
getting skipped if they coincided with page flips, which resulted in some
cursor movements failing to schedule the frame clock. This resulted in
unnecessary levels of frame skips when using lower frequency input devices
which are less likely to provide another event within the same frame period.
