e884e7c7b8 gl_renderer: log EGL features
Log EGL features similar to how GL ES features are logged: listing just
the ones weston tests for.

This replaces some log messages from gl-renderer.c that become
redundant or belong with EGL better.

has_native_fence_sync and has_wait_sync are not logged, because missing
them already logs warnings.

2f115047de gl-renderer: log rendering device
Feels like this might be nice to log.

The failure case is not fatal, so say it's a warning only.

ccb0d4f7ce gl-renderer: pass gr to gl_renderer_log_extensions()
Plumb struct gl_renderer all the way through to
gl_renderer_log_extensions(). In the future, the extension lists will be
printed into a debug scope specifically, and it will get the debug scope
from gr.

f9787ba482 gl-renderer: query DRM device given an EGLDisplay
Add function to query the DRM device given an EGLDisplay. It is the
device being used by the compositor to perform composition.

This will be useful in the next commits of this series, where we add
support for dma-buf feedback.

This is to put more of the EGL client extension handling in the same
place. This also adds a boolean to check if EGL_EXT_platform_base is
supported, similar to other extensions we check.

dddb592cfb gl-renderer: Move EGL client extension handling earlier
EGL client extensions are not tied to the EGLDisplay we create, and have
an effect on how we create the EGLDisplay. Since we're using this to
look for EGL_EXT_platform_base, it makes more sense for this to be near
the start of the GL renderer initialization.

c232f8d934 Unify the include style of shared/ headers
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/'

7ba4c515a3 gl-renderer: prefer the base EGLConfig
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().

5d6d2b10af gl-renderer: configs for pbuffers too
Fold more code into the common config choosing, the pbuffer path this time.
Simplifies code and allows gl_renderer_get_egl_config() to grow smarter in the
future to guarantee config compatility in the absence of configless_context
extension.

7cb7a6781f gl-renderer: remove EGLConfig attributes from API
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.

7cbafec8ae gl-renderer: fuzzy EGLConfig matching for non-GBM
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.

c01ba92eb2 gl-renderer: use pixel_format_info internally for EGL
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.

8e42af02a6 gl_renderer: introduce gl_renderer_get_egl_config()
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.

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
franca.
