Simon Ser 4c51a0f6eb render/egl: rename wlr_egl.exts to better match Khronos
Khronos refers to extensions with their namespace as a prefix in
uppercase. Change our naming to align with Khronos conventions.
This also makes grepping easier.

Simon Ser 8a4957570f render/egl: remove EGL_WL_bind_wayland_display support
Our GLES2 renderer doesn't use it anymore, so we can drop it.

Simon Ser 1db976cecb render/egl: replace wlr_egl_create with wlr_egl_create_with_drm_fd
We never create an EGL context with the platform set to something
other than EGL_PLATFORM_GBM_KHR. Let's simplify wlr_egl_create by
taking a DRM FD instead of a (platform, remote_display) tuple.

This hides the internal details of creating an EGL context for a
specific device. This will allow us to transparently use the device
platform [1] when the time comes.

Simon Ser a2419eb4ea render/egl: make most functions private
The wlr_egl functions are mostly used internally by the GLES2
renderer. Let's reduce our API surface a bit by hiding them. If
there are good use-cases for one of these, we can always make them
public again.

The functions mutating the current EGL context are not made private
because e.g. Wayfire uses them.

Simon Ser 101b9a193d render/egl: query and display EGL driver name
GL_RENDERER typically displays a human-readable string for the name
of the GPU, and EGL_VENDOR typically displays a human-readable string
for the GPU manufacturer. EGL_DRIVER_NAME_EXT should give the name of
the driver in use.

This is unused in wlroots, and the use-cases for compositors are

wlr_buffer.

Simon Ser b514d4afe2 render/egl: stop relying on platform for high priority
All backends use the GBM platform. We can't use it to figure out
whether the DRM backend is used anymore.

Let's just try to always request a high-priority EGL context. Failing
to do so is not fatal.

Simon Ser b89bcffea4 render/egl, backend/wayland: add workaround for split render/display setups
Split render/display setups have two separate devices: one display-only
with a primary node, and one render-only with a render node. However
in these cases the EGL implementation and the Wayland compositor will
advertise the display device instead of the render device [1]. The EGL
implementation will magically open the render device when the display
device is passed in.

So just pass the display device as if it were a render device. Maybe in
the future Mesa will advertise the render device instead and we'll be
able to remove this workaround.

Simon Ser 7f9bbaaa17 render/egl: explicit client extension handling
Prior to this commit, wlr_egl_init seemed to assume the extension string
queried via EGL_NO_DISPLAY was a subset of the extension string queried
via an initialized display. This isn't correct.

EGL_EXT_client_extensions [1] defines two types of extensions: client
extensions and display extensions. The set of supported client and
display extensions are disjoint (ie. an extension is either a client or
a display extension, not both). Client extensions are queried via
EGL_NO_DISPLAY, display extensions are queried via an initialized
display.

Rename the variables to make this clear. Remove the misleading comment.
Log both client and display extensions.

Simon Ser af2f69e6c1 render/egl: unset current context after swapping buffers
After swapping buffers, it doesn't make sense to perform more rendering

This commit makes it so the context is always only current between
wlr_egl_make_current and wlr_egl_swap_buffers.

This is an alternative to [1].

Simon Ser 01818ad2c8 render: fix EGL extensions not loaded
Some extensions are only advertised by the EGL implementation with a

enabled when the hardware/driver supports it for instance.

Instead of checking for all extensions without a display, check only for
EGL_EXT_platform_base and EGL_KHR_debug which are used before
eglGetDisplay. Check for all other extensions when we have a display.
