These "features" are somewhat less featured, it's becoming too ugly
to handle all of them with a single API call. The clear outlier are
buttons, so move them to a separate function.

queue_update() in a previous iteration was called in two situations:
* A page flip was already pending, meaning if we would commit an
update, it'd fail with EBUSY.
* A update was marked as "always-defer" meaning it should only be
processed from the deadline callback (would there be one). These were
used for cursor-only updates.
In the latter, we had to arm the deadline timer when queuing a new
update, if it wasn't armed already, while in the former, we would
currently idle, waiting for the page flip callback. At that callback
would the deadline timer be re-armed again.
Since we're only handling the former now, we'll never need to arm the
timer again, so remove code doing so. The code removed were never
actually executed anymore, after the "always-defer" flag on updates was
removed.

Primary plane updates were forgetting to do this in OnscreenNative, but
rather than do it for each post there we should simply do it for each
post.
This fixes cursor stutter in the fallback path (not using deadline timers)
where needs_flush_crtcs would remain populated but CRTC_NEEDS_FLUSH would
never be emitted, because handle_flush hadn't been called for the last
post.
This is safe as the current use of scheduled flushing is only for cursor
updates, and since cursor updates happen on the same thread as processing,
and due to the fact that we always use the most up to date cursor position
when flushing, we never risk leaving an old cursor state unflushed.

Implement importing of multi-plane formats. For now, only support
importing planes individually using "sub-formats". This is the most
commonly driver-supported approach in the moment, used by other
Wayland compositors as well.
In the future we will additionally want to support importing the formats
directly and let the drivers handle conversion internally.

So they can be derived from the DRM format as well.
While updating the users, ensure we don't announce support for
DRM formats in zwp_linux_dmabuf_v1 if the MetaMultiTextureFormat is
INVALID. This will be used for YUV subformats in following commits.

To be able to later support more complex YUV formats, we need to make
sure that MetaShapedTexture (the one who will actually render the
texture) can use the MetaMultiTexture class.

In future commits, we want to be able to handle more complex textures,
such as video frames which are encoded in a YUV-pixel format and have
multiple planes (which each map to a separate texture).
To accomplish this, we introduce a new object `MetaMultiTexture`: this
object can deal with more complex formats by handling multiple
`CoglTexture`s.
It supports shaders for pixel format conversion from YUV to RGBA, as
well as blending. While custom bleding is currently only required for
YUV formats, we also implement it for RGB ones. This allows us to
simplify code in other places and will be needed in the future once
we want to support blending between different color spaces.

When we see a mode set, the cursor manager will update all the cursor
planes so they are set correctly as part of the mode set. KMS updates
are always per-device, and what was wrong was that it didn't filter out
CRTCs on devices that wasn't part of the mode set.

It turns out that gnome-shell's toolbox image is still broken
after commit 86b77f65e7.
Toolbox' entry point ensures that the calling user exists inside
the container, and makes their home available inside the container.
There are two ways the `useradd` command in our image may interfere
with that:
- by default, useradd uses the smallest available UID in the
normal user range (usually 1000); this is highly likely to
clash with the host user UID
- if the host's /home is a symlink (for instance to /var/home
on Silverblue), then toolbox recreates that layout inside the
container; it cannot do that if /home is already a non-empty
directory
Luckily we can address both issues without affecting the ability
to build and run tests as user: We can simply create the `meta-user`
with a UID and home directory that are unlikely to clash.

Measurements above 100% were originally allowed to show when frame skipping
was occurring so you didn't have to also check the frame rate. But that
also resulted in arbitrarily high jitter values being reported when
returning from idle. And those are frequent enough to look like a bug or
untrustworthy so let's not do that anymore.
Taking the remainder of a high jitter value is still a meaningful jitter
value.

clutter_frame_clock_compute_max_render_time_us clamps to the refresh
interval anyway, so the only effect a higher recorded maximum can have
is to delay it falling below the refresh interval again.

Instead of separate pairs of short- and long-term maxima for each
measured step of the frame update process.
This should result in the render time estimate rising less often:
Previously it did whenever the measurement of any of at least 3 out of
4 steps reached a new maximum, even if that didn't result in a new
maximum for the whole update duration. Now it's only in the latter
case.
This should also result in a lower render time estimate (and thus
input→output latency) in general, since the variability of
measurements for each 3/4 steps doesn't always add up anymore. The flip
side of this is that it might result in missing a display refresh cycle
more often.
v2:
* Fix coding style in maybe_update_longterm_max_duration_us.

With libdecor, window moving/resizing only works with
the pointer, not with touch.
The meta_wayland_pointer_can_grab_surface checks for subsurfaces,
but the meta_wayland_touch_find_grab_sequence does not.
Add a similar subsurface check to
meta_wayland_touch_find_grab_sequence.
