We add a flow_id when we touch a surface that has no flow id, and clear
it when we flush damage, so a flow line will be drawn connecting any
operations on a surface and terminating in its damage clear.
This is less useful for surfaces that never receive explicit damage after
they're set up, such as background images and the panel, as they might
never show up as a damage track, and have an unterminated flow line.
For surfaces that do show up on a damage track, we can follow them back to
the commit that caused them to update.

Try to roughly achieve feature parity with WESGR by processing the same
timepoint data and feeding it into perfetto, with output and surface

We can't match the way WESGR draws this information, because perfetto has
a different display paradigm, but we can try to at least make sure all the
same information is visible in an understandable way.

The CM&HDR protocol extension spec relaxed the requirements for the
max_fall and max_cll setters. Now we accept such values even when the
transfer function is not PQ.
This also fixes an issue in which we'd not accept target_luminance
for transfer function different from PQ, which was not on the spec.
INCONSISTENT_SET is not being used in any other errors, so remove that

This would allow to screen-share a particular output like the
following:
[output]
name=vnc
same-as=DP-5
[output]
name=rdp-0
same-as=DP-4
[output]
name=pipewire
same-as=eDP-1
Both 'vnc', 'pipewire' 'rdp-0' remote outputs would then be a
screen-share 'DP-5', respectively, 'e-DP1', or the 'DP-4' DRM output.
Currently, this is intended only for VNC, RDP and PipeWire remote outputs.
This patch exports weston_output_set_position(), and uses that for
overlapping a remote output with a native DRM one, rather than using
weston_output_move() as that has a side-effect when reflowing outputs
from shells.
Further more creating this remote output is driven entirely by compositor
signal events such that enabling an DRM native output would enable the
remote output, while disabling the native would have the same outcome
for the remote one.

The main differences is the split of cm_surface functionality with
cm_surface and cm_feedback_surface.
There can only be one cm_surface to set, unset image descriptions. When
cm_surface is destroyed, the image description is automatically unset.
There can be multiple feedback_surfaces for one surface though.
Now the "preferred_changed" signal can be an initial event.

This new public API is intended to deliver EDID etc. information to the
frontend. The use case here is display colorimetry, to help the frontend
craft output image descriptions (color profiles).
The frontend will need to link to and use libdisplay-info to make use of
this. This avoids having to replicate in libweston the high-level API
that libdisplay-info already has. The libdisplay-info API is also likely
to be extended, and it is not nice to play catch-up with it.
As a di_info can only be destroyed by calling into libdisplay-info,
libweston core can only ensure it has already been freed. There is not
enough reason to make libweston core depend on libdisplay-info, only the
DRM-backend is.
It will be up to DRM-backend to ensure display_info is updated and
device_changed is set only when necessary.

After c08a6ff8 moved attach to the render loop, we have a bad situation
when clients delete an attached shm buffer. We try to query the stride
at attach time, but the shm_buffer has been destroyed, and we crash.
Instead of carefully fixing that, I've instead stored the stride at
buffer creation time (as we already do with buffer width and height).
This lets attach succeed in the gl-renderer, keeping the old texture data
available for any upcoming rendering.

Currently only the return value of the last backend that implements
repaint_flush() is actually used. That only works because the drm backend is the
only backend that implements repaint_flush().
In the drm backend only the return value of the last device is used. And if a
failure is actually detected, then all repainted outputs of all backends are
reset. This can trigger asserts:
weston_output_schedule_repaint_reset() (or _restart()) will change the state of
the output but the backend that did not cause the failure will still call
weston_output_finish_frame().
The same thing can happen with multiple devices in the drm backend. Or outputs
get stuck if an error is dropped.
Since the drm backend is the only one that implements repaint_flush() anyways,
move the failure handling into the backend and make it device specific.
This way only the outputs that need it are reset.

When a repaint is triggered then not all backends may have outputs that need to
be repainted.
Check which outputs will be repainted first and then repaint only the backends
that need it.
This way unnecessary repaint_begin() and repaint_flush()/repaint_cancel() can
be skipped and errors are handled for each backend separately.

Add API to create color profiles from parameters. It is a public API
that should be used by the frontend and also by the color management
protocol implementation.
Currently our protocol implementation does not support clients that want
to create color profiles from parameters, and this is a step towards
supporting that.
As warned in "color: add get_color_profile_from_params() to color
managers", we still do not fully support creating color profiles from
parameters. This just creates a boilerplate color profile that we're
planning to extend later.

This API is mostly for use by the DRM-backend. Colorimetry mode is is
the KMS connector property "Colorspace" which defines the video signal
encoding colorimetry. A video sink indicates the supported modes in EDID
or DisplayID.
This patch adds the libweston API that allows backends to indicate the
supported modes for the frontends, and frontends to set the mode to be
used by backends. Colorimetry mode does not directly affect color
management inside Weston, it is only metadata for the video sink. It is
the frontend's responsibility to set up an output color profile that
agrees with the colorimetry mode. (That API has not been implemented
yet.) eotf_mode will be the same.
There is only one reason to make this a libweston core API instead of
a backend-drm API: when wayland-backend gains color-management protocol
support, meaning it can forward WCG and HDR content correctly to a
host compositor, the supported colorimetry modes can be determined from
the host compositor's supported color-management features, allowing the
guest Weston to pick some other output image description than the host
compositor's preferred image description. This likely allows only a few
other choices from standard colorspaces, so it's possible this isn't
sufficient for that use case.
Either way, it is easy to just copy the eotf_mode API design, and since
colorimetry_mode and eotf_mode go together, let both have the same API
design. It is possible to convert this to backend-drm API later.

That means that we are able to advertise output's images descriptions to

set such descriptions for surfaces.
