This replaces some log messages from gl-renderer.c that become

has_native_fence_sync and has_wait_sync are not logged, because missing

Now that the gl_buffer_state owns everything related to buffers, move

Now that EGLImages are strongly associated with a gl_buffer_state, which

... apart from SHM.
EGL and dmabuf buffers already have a gl_buffer_state created for them
when we first attach the weston_buffer. By turning
gl_surface_state::buffer into a pointer, we can just reference rather
than inline the gl_buffer_state.
SHM buffers are special, in that we don't keep individual copies of them
within the GL renderer. Instead, the GL surface has a texture allocated
with a shadow copy of the most up-to-date surface content. Handle this
by allocating and destroying gl_buffer_state every time we need to
respecify textures or somehow meaningfully change the parameters.

Similarly to EGL buffers, store the gl_buffer_state for a dmabuf buffer
inside weston_buffer, rather than on the linux_dmabuf_buffer. This
slightly simplifies our gl_buffer_state handling, and will be used later
to eliminate the egl_image refcounting.
Signed-off-by: Daniel Stone <daniels@collabora.com>
Introduce a renderer_private hook for weston_buffer, and use this to
store a copy of the gl_buffer_state for EGL buffers (i.e. non-dmabuf, via
EGL_WL_bind_wayland_display).
As part of this, we create the EGLImage along with the weston_buffer
information, and just take a reference to it each time it is attached.
If you have bisected a failure to update surface content to this commit,
it very likely means that your EGL implementation requires images to be
recreated rather than only rebound in order to have their content
updated, which is contrary to specification.

At the moment, attach_shm() will modify the gl_buffer_state in place,
then compare it and see if it differs enough to require a new one. That
rather mixes up the old and new worlds, so quite explicitly build up a
shadow gl_buffer_state with variables first before we change the one
which already exists.

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.
