We may have DRM LUT's for u32 and u16. This allow us to create both
types. Should be useful in the next commit.
u16 is used for legacy GAMMA_LUT, and u32 will be used for the newer
colorops in the next commits.

Follow-up of "backend-drm: offload post-blend only if libdrm >=
2.4.130". This moves code related to offloading post-blend color xform
to colorops.c, which is built only if libdrm >= 2.4.130 is available.

In commit "backend-drm: introduce color pipelines" we've started adding
support for KMS plane color pipelines, which require libdrm >= 2.4.130.
The final goal is using color pipelines to offload pre-blend color
transformations.
Currently we support offloading post-blend color transformations even
with older libdrm versions, but that is not very useful by itself.
This patch makes offloading post-blend color transformations dependent
on the libdrm version as well. This allows keeping the code to offload
pipelines in a single file (which is built only if libdrm >= 2.4.130),
avoiding lots of #ifdefs and making the code easier to follow.

This adds support to the kernel proposal that introduces per-plane color
pipelines. For now it only manages the lifetime of the kernel objects
related to that.
In the next commits we start using all that to offload Weston pre-blend
color transformations to KMS.

We use this struct to cache and avoid creating multiple blobs for the
same 3x1D LUT. So let's rename to better reflect that.

We usually use the variable name 'ec' for struct weston_compositor. We
currently use the same in our assert macros, bringing issues.
Rename 'ec' to 'wc_' in our assert macros, avoiding this kind of issue.
Also, this fixes a weston_assert_ macro call in which we forgot to
declare 'ec' before calling it.

A few custom shells want to know when the compositor is going to sleep.
This adds a new sleep signal and emits it when DPMS is going off.
To showcase the feature, this adds a sleep signal listener to
desktop-shell whose handler logs a message.

When we receive dmabuf feedback, we hit the VK_SUBOPTIMAL path and
recreate the swapchain, returning early without submitting work.
However, we've already reset the fence before we do this, so we'll
block forever waiting for work that never comes to signal it.
Instead, we should reset the fence right before we know we're submitting
work.

Since the commit "color-lcms: extract HDR static metadata from profile"
this was all dead code.
Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
Extract the HDR static metadata type 1 from the output color profile
directly, instead of relying on a separate weston.ini section to provide
the metadata separately.
Weston should tell the monitor what target color volume it is rendering
for. I don't see a reason to be able to control the metadata separately,
and it would add complexity.

The point of buffer_transform_split is to ensure that committing only
transform and scale changes gets reflected on screen, without explicit
damage. There is no need to go through the big set of parameter
combinations, it only needs to test that changing each triggers the
damage.
Test setting only scale and only transform separately, so that one
cannot mask bugs with the other.
This brings the screenshot count for buffer_transform_split from 12 down
to 2, which is good for CI running time.

This test was originally written to ensure Weston does not repaint too
much, but it does also test that renderers transform the damage
correctly into the framebuffer.

The paint_node life cycle should match the output's, so we should be able
to store it in the state instead of a view.
This gets us closer to having the backends stop caring about views.

We already validate the paint node list in weston_output_repaint,
immediately after we conditionally rebuild the z_order_list.
These asserts are thus completely redundant, as we've already
performed them in the front end.
My reason for removing this now is to drop weston_view usage
from the backend.

Backends work on paint nodes, not views - and the paint node internal
name is a superset of the view internal name anyway, so it's not hard to
figure out which view a paint node belongs to when reading debug text.

The failure reason is already part of the paint node, so passing the view
here just makes things a little bit more complicated.

Backends should be relying on paint nodes for their information, not
views.
Since we always have a paint node when we want to pass a buffer, we can
pass that instead of a view.

This avoids ICC paths when no ICC profiles are explicitly used.
We can simplify the profile information sending and use the generic path
for the stock profile as well, no longer hard-coding the stock profile
in two places.
Since the stock profile creation cannot fail, we can streamline
cmlcms_init() a little, too.
