ubsan doesn't like what we were doing here:
../libweston/compositor.c:3021:21: runtime error: signed integer overflow: -2147483648 + -1 cannot be represented in type 'int'
Rather than try to be clever in invoking weston_layer_set_mask, just build the
maximal mask explicitly.
weston_compositor_build_view_list can reconstruct the view_list without a view which was
previously in it. The existing pointers in view->link are left unchanged, which could
lead to corruption or access to released memory in wl_list_remove, depending of the
order of destruction of the views.
This can happen at least with the black view created by the desktop shell for fullscreen
surfaces, when it is hidden in lower_fullscreen_layer.

Use the surfaceless platform in the headless backend to initialize the
GL-renderer and create pbuffer outputs. This allows headless backend to use
GL-renderer, even hardware accelerated.
This paves way for exercising GL-renderer in CI and using the Weston test suite
to test hardware GL ES implementations.

Since the RDP backend allocates regular memory already as hw buffer
anyway, a shadow buffer is not required. The read_pixels interface
anyway renders directly into the hardware buffer, hence this does
not make a performance difference in practise. It avoids allocating
an unnecessary buffer.

Define common_inc which includes both public_inc and the project root directory.
The project root directory will allow access to config.h and all the shared/
headers.
Replacing all custom '.', '..', '../..', '../shared' etc. include paths with
common_inc reduces clutter in the target definitions and enforces the common
#include directive style, as e.g. including shared/ headers without the
subdirectory name no longer works.
Unfortunately this does not prevent one from using private libweston headers
with the usual include pattern for public headers.
Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
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/'

If configless_context is not supported, we pick one EGLConfig as the "base
config" because we have just one GL context and different configs between the
context and EGLSurfaces might not work. Until now, we did not actually make
sure to pick the base config.
If the base config matches the requirements, prefer it. Only if it doesn't
match, go looking for another config.
This should give better chances of success on systems where configless_context
is not supported by relying less on eglChooseConfig().

If we don't have the surfaceless_context extension, we create a pbuffer as a
dummy surface to work with. If we also don't have configless_context, then it
is possible the config used for creating the context does not support pbuffers.
Therefore, if both conditions apply, we need to pick a config that supports
both window and pbuffer surfaces.
This makes the "base" config compatible, but it does not yet guarantee that we
actually pick it again when creating the pbuffer surface. Fixing that is
another patch.

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.

Implement fuzzy EGLConfig pixel format matching, where we ensure that R, G, B
and A channels have the expected number of bits exactly. This is used on EGL
platforms where the EGLConfig native visual ID is not a DRM format code. On EGL
GBM platform, the old exact matching of native visual ID is kept.
As only the DRM backend uses a DRM format list for picking a config, this patch
should not change any behaviour.

Using arrays of pixel_format_info instead of just DRM format codes is useful
for fuzzy matching of formats with EGLConfigs in the future. The immediate
benefit is that we can easily print format names in log messages.
We should never deal with formats we don't have in our database, so discarding
unknown formats should be ok. Using unknown formats would become hard later,
too.

These fields are necessary when looking for an EGLConfig matching a pixel
format, but the configs do not expose a native visual id. Such happens on the
EGL surfaceless platform where one does not actually care about the exact pixel
format, one just cares it has the right number of bits for each channel and the
right component type.
FP16 formats are coming, so this paves way for them too, allowing them to be
described.
The FIXED/FLOAT terminology comes from EGL_EXT_pixel_format_float.

Replace a direct call to egl_choose_config() with a higher level function

attribute lists will be generated inside gl_renderer_get_egl_config() instead
of passed in as is.
We explicitly replace visual_id with drm_formats, because that is what they
really are. Only the DRM backend passes in other than NULL/0, and if other
backends start caring about the actual pixel format, drm_format is the lingua

In an attempt to pull more of EGLConfig choosing into one place, refactor code
into the new gl_renderer_get_egl_config(). The purpose of this function is to
find an EGL config that not only satisfies the requested attributes and the
pixel formats if given but also makes sure the config is generally compatible
with the single GL context we have.
All this was already checked in gl_renderer_create_window_surface(), but
gl_renderer_create_pbuffer_surface() is still missing it. This patch is
preparation for fixing the pbuffer path.

Some drivers support EGL_EXT_image_dma_buf_import_modifiers for format
enumeration, but don't have any modifiers. In this case, on platforms where
malloc(0) returns non-NULL, we would leak that allocation to the caller.
Handle this by noticing when the number of supported modifiers is 0 and
returning early.

In case of enforced protection mode, the renderer takes care of

But in case of relaxed protection mode, the client must be notified to

with relaxed protection mode, and notifies the client, whenever the
recording is started or stopped.
