Similar to how we do it with drm_fb ref counts, increase a reference
count and return the same object.
Plug-in in desktop-shell when we map up the view in order to survive a
weston_surface destruction.
Astute readers will notice that this patch removes weston_view_destroy()
while keeping the balance between removing and adding a
weston_surface_unref() call in desktop_shell_destroy_surface().
The reason is to let weston_surface_unref() handle destruction on its
own. If multiple references are taken, then weston_surface_unref()
doesn't destroy the view, it just decreases the reference, with
a latter call to weston_surface_unref() to determine if the view
should be destroyed as well. This situation happens if we have
close animation enabled, were we have more than one reference taken: one
when mapping the view/surface and when when the surface itself was created,
(what we call, a weak reference).
If only a single reference is taken (for instance if we don't have close
animations enabled) then this weston_surface_unref()
call is inert as that reference is not set-up, leaving libweston to
handle the view destruction.
Following that with a weston_view_destroy() explicit call would cause a
UAF as the view was previous destroyed by a weston_surface_unref() call.
A side-effect of not keeping the weston_view_destroy() call would
happen when tearing down the compositor. If close animations are enabled,
weston_surface_unref() would not destroy the view, and because
weston_view_destroy() no longer exists, we would still have the
view in the other layers by the time we check-up if layers
have views present.

To me, the use of setup_search_param() makes the code harder to
understand than it needs to be. Replacing that function with open-coding
the struct cmlcms_color_transform_search_param initialization makes it
more clear that:
- get_surface_color_transform is the only one that actually uses a
surface to initialize it
- get_blend_to_output does not use an input profile at all
- get_sRGB_to_output and get_sRGB_to_blend hardcode the sRGB profile
like they should

I am going to need to add yet another output property to be set by a
color manager: HDR Static Metadata Type 1. With the old color manager
API design, I would have needed to add the fourth function pointer to be
called always in the same group as the previous three. This seemed more
convoluted than it needs to be.
Therefore collapse the three existing function pointers in the API into
just one that is resposible for setting up all three things.

This new struct collects all the things that a color manager needs to
set up when any colorimetry aspect of an output changes. The intention
is to make the color manager API less verbose.
In this first step, the new struct is added and replaces the fields in
weston_output.
The intention is for the following color manager API changes to
dynamically allocate this structure. Unfortunately, until that actually
happens, we need a temporary way to allocate it. That is
weston_output::colorout_, which will be removed in the next patch. This
keeps the patches more palatable for review at the cost of some
back-and-forth in code changes.
This is a pure refactoring, no functional changes.

Trying to do HDR with XRGB8888 is a bit like using RGB565 on SDR: you
get visible color quantization and banding in gradients (without dithering
which Weston does not implement yet, and might not work too well for HDR
anyway).
Therefore, on any HDR mode, default output framebuffer format to 10 bpc
instead of 8 bpc.
Ideally we'd also optionally try 16F or 16 bpc formats, but automatic
fallbacks for those are more complicated to arrange. You can still
configure 16F or 16 bpc manually.
This patch also moves the default format setting from
drm_output_set_gbm_format() to drm_output_enable(), because setting the
default now requires eotf_mode. Frontends may call set_gbm_format()
first and set eotf_mode next. This does create an awkward situation for
outputs that a frontend disables and re-enables. This patch here makes
sure that the old output configuration remains, but changing eotf_mode
may not change the default format. One needs to call
set_gbm_format(NULL) to re-evaluate the default format. Resetting the
format on drm_output_deinit() would lose the current setting.
DRM_FORMAT_INVALID was introduced in libdrm 2.4.95 which we already
hard-depend on.

Program the connector property HDR_OUTPUT_METADATA based on the EOTF
mode of the output.
For now, this changes only the EOTF. The colorimetry and luminance are
left undefined, to be filled in by later patches. This should still be
enough to put a video sink into HDR mode, albeit the response is
probably unknown.
drm_output keeps track of the currently existing blob id. If the blob
contents need to be re-created, this blob would be destroyed and the
field set to zero. In this patch, there is no provision for runtime
changing of HDR metadata, so there is no code doing that.
Destroying the blob at arbitrary times is not a problem, because the
kernel keeps a reference to the data as long as the blob id remains with
KMS.

Check whether HDR_OUTPUT_METADATA property exists on a KMS connector. If
yes, pretend that EDID claims support for all EOTF modes and update the

later.

These are fallback definitions in case libdrm is not new enough.
They are copied from libdrm 2.4.107.
struct hdr_output_metadata defines the contents of the blob to be used
with the connector property "HDR_OUTPUT_METADATA".
This is needed for programming a HDR mode in KMS.

This is the switch to turn HDR mode on.
The values in the enumeration come straight from CTA-861-G standard.
Monitors advertise support for some of the HDR modes in their EDID, and
I am not aware of any other way to detect if a HDR mode actually works
or not. Different monitors may support different and multiple modes.
Different modes may look different. Therefore the high-level choice of
how to drive a HDR video sink is left for the Weston frontend to decide.
All the details like what HDR metadata to use are left for the color
manager.
This commit adds the libweston API for backends to advertise support and
for frontends to choose a mode. Backend and frontend implementations
follow in other commits.
The frontend API does not limit the EOTF mode to the supported ones to
allow experimentation and overriding EDID.

Rather than punching through to set the surface as a solid colour,
attach an actual weston_buffer to it instead.
This becomes the first user of attaching non-client-generated buffers
to a weston_surface. As a result, it is necessary to introduce a
function which will allow compositors and shells to attach a buffer to a
surface. weston_surface_attach_solid() is therefore introduced as a
special-purpose helper which will attach a solid buffer to a
weston_surface.
It is not intended as a general-purpose mechanism to allow compositors
to attach client-generated buffers to surfaces, as doing so would have
unknown effects on this core part of the compositor itself.
