Add a create_image_from_ptr vfunc to struct pixman_renderer_interface,
which wraps weston_renderbuffer creation for the pixman renderer via
pixman_image_create_bits(), as well as a renderbuffer_destroy vfunc
to dispose of the pixman image renderbuffer.
Also add create_image_no_clear using pixman_image_create_bits_no_clear()
instead.
Make the backends create and destroy their pixman image renderbuffers
through this interface.

Move the struct gl_renderer_interface pointer from the backends into
the weston_renderer structure. The interface struct only contains
function pointers that never change, so make it const.
Load and initialize the GL renderer in libweston instead of in the
backends, using the new weston_compositor_init_renderer() function.

To avoid retrieving the backend from the compositor all the time, store
a pointer to the x11 backend on its x11_output structures.
This will be useful once the compositor contains more than one backend.

Passing the backend as a parameter to the weston_backend function
pointers seems more natural and will be very useful once there can be
more than one backend.
Since all backends already store a pointer to the compositor instance,
replace the compositor parameter with the backend in all functions.

Compositor code can use opaque pointer comparison to determine whether
a head belongs to a given backend. Store a backend pointer in struct
weston_head to enable the compositor to select the correct backend
specific output configuration code.
This also allows to use the backend pointer instead of the opaque
backend_id pointer to check whether a head belongs to a backend, so
replace the checks in all to_xyz_head() functions and drop backend_id.

This will help later when manufacturing garbage coordinates becomes much

This changes the GL-renderer interface to pass the initial framebuffer
size and compositing area explicitly. All backends are changed to
provide the correct parameters.
GL-renderer mostly does not yet use these values, but later patches
will. The pbuffer path uses it already, because they replaced the
existing fields.
All this is to make GL-renderer aware of the different sizes, so it can
implement the future revision of the screenshooting API.

Rather than doing it with a local variable, track any previous events by
hanging it out of the x11 backend and use it to handle keymap notify
events.
In this way we avoid corrupting the surface destroy signal list, in
notify_keyboard_focus_out(), ultimately leading to a crash.

As a first step towards heterogeneous outputs, ignore other backends'
heads and outputs. This is done by checking the destroy callbacks for
heads and outputs.

The repaint_data is entirely backend specific. Moreover, it is only used by the
drm backend, while other backends ignore the repaint data.
There will always be only one repaint active, thus, there is no need to pass the
repaint data from the outside.
The repaint_data breaks with the multi-backend series, which calls repaint begin
for all backends to get the repaint_data. The repaint_data of the last backend
will then be passed to all other backend. At the moment, this works, because the
drm backend is the only backend that implements the begin_repaint call.
Another option would be to track the repaint data per backend in the compositor,
but actually, it the backend needs to track state across the calls, it's its own
responsibility.

This header is for sharing fallback definitions for drm_fourcc.h. A new
test in tests/yuv-buffer-test.c is going to be needing XYUV8888 format,
and more new formats will be expected with HDR supports.
Share these fallback definitions in one place instead of copying them
all over.
All users of drm_fourcc.h are converted to include weston-drm-fourcc.h
instead for consistency: have the same definitions available everywhere.

When all shared/ headers are included in the same way, we can drop unnecessary
include seach paths from the compiler.
This include style was chosen because it is prevalent in the code base. Doing
anything different would have been a bigger patch.
This also means that we need to keep the project root directory in the include
search path, which means that one could accidentally include private headers
with
#include "libweston/dbus.h"
or even
#include <libweston/dbus.h>
IMO such problem is smaller than the churn caused by any of the alternatives,
and we should be able to catch those in review. We might even be able to catch
those with grep in CI if necessary.
The "bad" include style was found with:
$ for h in shared/*.h; do git grep -F $(basename $h); done | grep -vF '"shared/'

Now that all backends pass in a list of acceptable DRM formats, that is used to
determine if the EGLConfig has an alpha channel or not. Therefore the
opaque_attribs and alpha_attribs are now useless, and we can remove the whole
config_attribs argument from the API.
gl_renderer_get_egl_config() uses an internal attrib list that matches at least
the union of the opaque_attribs and alpha_attribs matches.
Overall, behaviour should remain unchanged.
The new attribute array becomes variable in the future, so it is left
non-const.

Define a specific DRM format for the GL-renderer to render in. It goes through
fuzzy matching in egl-glue.c which ensures we get exactly the number of bits
for each channel, but does not require an exact format match.
This ensures we get the bit depth we expect instead of the first arbitrary
EGLConfig.
This should not change the current behaviour, because Mesa EGL takes care to
order the configs as apps expect.

Depending on system loading, weston-launcher could drop the drm
master access before the compositor and all the clients receive
the notification. In this case, some commit could be sent to the
drm driver too late and get refused with error EACCES.
This error condition is not properly managed and causes weston to
hang.
Change the return type of start_repaint_loop() and repaint_flush()
from void to int, and return 0 on success or -1 if the repaint has
to be cancelled.
In the callers of start_repaint_loop() and repaint_flush() handle
the return value and cancel the repaint when needed.
In backend-drm detect the error EACCES and return -1.
Note: to keep the code cleaner, this change inverts the execution
order between weston_output_schedule_repaint_reset() and
repaint_cancel().
No need to wait for suspend or for any notification; in case the
weston reschedules a repaint, it will get EACCES again.
At resume, damage-all guarantees a complete repaint.
This fix is for atomic modeset only.
Legacy modeset suffers from similar problems, but it is not fixed
by this change. Since drm_pending_state_apply() never returns
error for legacy modeset, this change has no impact on legacy
modeset.
