This new EGL extension has been introduced in [1].
When we have a DRM device and a render node, we can advertise the
extension and return the render node name for the
EGL_DRM_RENDER_NODE_FILE_EXT query.
For the special software EGL device, we can advertise the extension
and return NULL for the EGL_DRM_RENDER_NODE_FILE_EXT query, because
we can guarantee that llvmpipe will never use a render node for
rendering operations.
However, llvmpipe might be using a primary node when used with the
GBM platform. So we can't advertise EXT_device_drm in this case.
When we have a DRM device but no render node, that means we're on a
split render/display SoC. We _should_ return the render node used
by the renderonly driver, however Mesa needs more plumbing to allow
this, so let's just disable the extension for now.

This reverts commit 5743a36b2b.
Now that _eglAddDevice is always called with the correct software
hint, no need to bail out if the device doesn't have a render node.
On split render/display SoCs, the DRM device won't have a render
node, yet rendering is hardware-accelerated (via kmsro).

We don't want to expose an EGL device for a display-only DRM devices
(like VKMS). For these DRM devices we have a separate software-rendering
device (the first in the list, always present).
There is a similar check in _eglAddDRMDevice, however it will be
removed in a future commit to allow split render/display devices
to be properly added. We can't figure out whether we're on a split
render/display system before loading the driver.

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.

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

This function was never used, and isn't properly guarded by HAVE_LIBDRM,
breaking the build on systems that don't have libdrm.
Let's just remove it.

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)

Add a plain software device, which is always available.
We can safely assign it as the first/initial device in _eglGlobals,
although we ensure that's the case with a handful of _eglDeviceSupports
checks throughout the code.
v2:
- s/_eglFindDevice/_eglAddDevice/ (Eric)
- s/_eglLookupAllDevices/_eglRefreshDeviceList/ (Eric)
- move ^^ helpers into a earlier patch (Eric, Mathias)
- set the SW device on _eglGlobal init. (Eric)
- add a number of _eglDeviceSupports checks (Mathias)
- split Device/Display attach to a separate patch
v3:
- flip inverted asserts (Mathias)
- s/on-stack/static/ (Mathias)

Introduce the API for device query and enumeration. Those at the moment
produce nothing useful since zero devices are actually available.
That contradicts with the spec, so the extension isn't advertised just
yet.
With later commits we'll add support for software (always) and hardware
devices. Each one exposing the respective extension string.
v2:
- fold API boilerplate into this patch
- move _eglAddDevice, _eglDeviceSupports, _eglRefreshDeviceList to this
patch (Eric, Mathias)
- make _eglFiniDevice the one called last
v3:
- comment on the dummy _egl_device_extension enum entry (Eric)
- annotate dev as MAYBE_UNUSED (Mathias)
