st/egl used to support eglCreatePbufferFromClientBuffer, but now that
it's gone, any call to it would segfault.

Nobody ever uses these, so let's just hard code them instead.

If an EGL driver ever comes around that needs them they're trivial to
re-add.

Eric Engestrom 188dbb1679 Revert "egl: drop empty eglfallbacks.c" and "egl: move fallback calls to eglapi.c"
This reverts commits cc4b68a801 and
b27fb3eaca.

These caused a bunch of EGLSync tests to crash when they were previously
failing.

I have a hunch the tests are doing something wrong, like using
extensions without checking for they support, but until the issue is
investigated I'm just reverting these commits.

Mathias Fröhlich 5743a36b2b egl: Don't add hardware device if there is no render node v2.
Do not offer a hardware drm backed egl device if no render node
is available. The current implementation will fail on this
egl device. On top it issues a warning that is actually missleading.
There are finally more error paths that can fail on the way to a
hardware backed egl device. Fixing all of them would kind of require
opening the drm device and see if there is a usable driver associated
with the device. The taken approach avoids a full probe and fixes at
least this kind of problem on kvm virtualization hosts I observe here.

Emil Velikov d6edccee8d egl: add EGL_platform_device support
This new 'platform' is added by default with no guards.

It is effectively a copy of the surfaceless one, with updated function
names and brand new probe function.

Due to the reuse, some of the ifdef HAVE_SURFACELESS_PLATFORM guards
have been dropped.

A worthy mention are the changes in _egFindDisplay, since the original
and dup'd fd are required, we make use of the plat_opt argument.

Note that no hacks for eglGetDisplay are added - the API works only with
the eglGetPlatformDisplay* API.

v2:
 - s/_eglCompareDeviceDisplay/_eglSameDeviceDisplay/ (Eric)
 - let ^^ return bool (Eric)
 - fixup meson build, move files() further up (Eric)
 - copy from plat. surfaceless w/o the visual cleanups
 - close and free when destroying the dpy
 - sprinkle a few _eglDeviceSupports
 - split fd handling into separate function
 - use directly the render node if no FD is given (Mathias)

v3:
 - s/dpy/disp/g
 - drop swap_buffers* callbacks
 - drop loader_set_logger()
 - drop local define
 - re-introduce _eglGetDRMDeviceRenderNode()
 - EGL_WARN on ForceSoftware with HW device - continue using the HW device
 - bail out for "EGL_MESA_device_software" until it's fixed
 - wire-up the Android build

v4:
 - use new style _eglFindDisplay()
 - split hw vs sw code paths
 - don't close the internal fd (already handled in FiniDisplay())
 - make swrast work (bit hacky bit will do for now)
 - Android for real, drop autotools
 - Correct HW + LIBGL_ALWAYS_SOFTWARE check
 - use the dri2_create_drawable() helper

v5:
 - enhance comment around fd checks (Mathias)
 - rebase for dri2_init_surface() changes

Kenneth Graunke 28c2ce7105 egl: Allow EGL_CONTEXT_OPENGL_RESET_NOTIFICATION_STRATEGY in ES and GL
EGL annoyingly defines a few variants of this token:

   EGL_CONTEXT_OPENGL_RESET_NOTIFICATION_STRATEGY_EXT - 0x3138
   EGL_CONTEXT_OPENGL_RESET_NOTIFICATION_STRATEGY_KHR - 0x31BD
   EGL_CONTEXT_OPENGL_RESET_NOTIFICATION_STRATEGY     - 0x31BD

The EGL_EXT_create_context_robustness extension specifies that the EXT
token is only valid for ES contexts, not GL.  The EGL_KHR_create_context
extension defines the KHR version, and says it is only allowed for GL
contexts, and specifically calls out that it's an error for ES contexts.

But EGL 1.5 includes the new suffixless token, which has the same value
as the KHR version, and specifically calls out that it's now valid to
use with both GL and ES contexts.  So we should allow this.

Fixes KHR-NoContext.es32.robustness.no_reset_notification and
KHR-NoContext.es32.robustness.lose_context_on_reset on iris, which
apparently is exposing EGL 1.5.

Paulo Zanoni 04ecda3b3c egl: store the native surface pointer in struct _egl_surface
Each platform stores this in a different place:
  - platform_drm uses dri2_surf->gbm_surf->base
  - platform_android uses dri2_surf->window
  - platform_wayland uses dri2_surf->wl_win
  - platform_x11 uses dri2_surf->drawable
  - platform_x11_dri3 uses dri3_surf->loader_drawable.drawable
  - haiku doesn't even store it!

We need access to the native surface since the specification asks us
to refuse creating a new surface if there's already an EGLSurface
associated with native_surface.

An alternative to this patch would be to create a new
API.GetNativeWindow callback that each platform would have to
implement. While that's something we can definitely do, I prefer
this approach.

Emil Velikov c7cc135e23 egl: enable EGL_EXT_device_{base,enumeration,query}
Now that we support the extensions, fully, enabled them.

The specs mandate that we always have at least one device and each dpy
has a device associated with it.

Emil Velikov dbb4457d98 egl: add EGL_EXT_device_drm support
Add implementation based around the drmDevice API. As such it's only
available only when building with libdrm. With the latter already a
requirement when using !SW code paths in the platform code.

Note: the current code will work if a device is hot-plugged. Yet
hot-unplugged is not implemented, since I have no ways of testing it.

v2:
 - ddd some _eglDeviceSupports checks
 - require DRM_NODE_RENDER
 - add _eglGetDRMDeviceRenderNode helper

v3:
 - flip inverted asserts (Mathias)
