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

`EGLDisplay` variables (the opaque Khronos type) have mostly been
consistently called `dpy`, as this is the name used in the Khronos
specs.
However, `_EGLDisplay` variables (our internal struct) have been
randomly called `dpy` when there was no local variable clash with
`EGLDisplay`s, and `disp` otherwise.
Let's be consistent and use `dpy` for the Khronos type, and `disp`
for our struct.

Imagine there are 2 threads that both call _eglGetNativePlatform()
simultaneously:
- thread 1 completes the first "if (native_platform ==
_EGL_INVALID_PLATFORM)" check and is preempted to do something else
- thread 2 executes the whole function, does "native_platform =
_EGL_NATIVE_PLATFORM" and just before returning it's preempted
- thread 1 wakes up and calls _eglGetNativePlatformFromEnv() which
returns _EGL_INVALID_PLATFORM because no env vars are set, updates
native_platform and then gets preempted again
- thread 2 wakes up and returns wrong _EGL_INVALID_PLATFORM
Solve this by doing the detection in a local var and only overwriting
the global one at the end, if no other thread has updated it since.
This means the platform detected in the thread might not be the platform
returned by the function, but this is a different issue that will need
to be discussed when this becomes possible.

Enable EGL_EXT_platform_base and the Linux platform extensions layered
atop it: EGL_EXT_platform_x11, EGL_EXT_platform_wayland,
and EGL_MESA_platform_gbm.
Tested with Piglit's EGL_EXT_platform_base tests under an X11 session.
To enable running the Wayland and GBM tests, windowed Weston was running
and the kernel had render nodes enabled.
I regression tested my EGL_EXT_platform_base patch set with Piglit on
Ivybridge under X11/EGL, standalone Weston, and GBM with rendernodes. No
regressions found.

Internally, much of the EGL code uses EGLNativeDisplayType,
EGLNativeWindowType, and EGLPixmapType. However, the EGLNative type
often does not match the variable's actual type.
The concept of EGLNative types are a bad match for Linux, as explained
below. And the EGL platform extensions don't use EGLNative types at all.
Those extensions attempt to solve cross-platform issues by moving the
EGL API away from the EGLNative types.
The core of the problem is that eglplatform.h can define each EGLNative
type once only, but Linux supports multiple EGL platforms.
To work around the problem, Mesa's eglplatform.h contains multiple
definitions of each EGLNative type, selected by feature macros. Mesa
expects EGL clients to set the feature macro approrpiately. But the
feature macros don't work when a single codebase must be built with
support for multiple EGL platforms, *such as Mesa itself*.
When building libEGL, autotools chooses the EGLNative typedefs based on
the first element of '--with-egl-platforms'. For example,
'--with-egl-platforms=x11,drm,wayland' defines the following:
typedef Display* EGLNativeDisplayType;
typedef Window EGLNativeWindowType;
typedef Pixmap EGLNativePixmapType;
Clearly, this doesn't work well for Wayland and GBM. Mesa works around
the problem by casting the EGLNative types to different things in
different files.
For sanity's sake, and to prepare for the EGL platform extensions, this
patch removes from egl/main and egl/dri2 all internal use of the
EGLNative types. It replaces them with 'void*' and checks each explicit
cast with a static assertion. Also, the patch touches egl_gallium the
minimal amount to keep it compatible with eglapi.h.

The null platform has no window or pixmap surface (but pbuffer surface).
And the only valid display is EGL_DEFAULT_DISPLAY. It is useful for
offscreen rendering. It works everywhere becase no window system is
required.
EGL doesnt define howto manage different native platforms.
So mesa has a builtime configurable default platform,
whith non-standard envvar (EGL_PLATFORM) overwrites.
This caused unneeded bugreports, when EGL_PLATFORM was forgotten.
Detection is grouped into basic types of NativeDisplays (which itself
needs to be detected). The final decision is based on characteristcs
of these basic types:
File Desciptor based platforms (fbdev):
- fstat(2) to check for being a fd that belongs to a character device
- check kernel subsystem (todo)
Pointer to structuctures (x11, wayland, drm/gbm):
- mincore(2) to check whether its valid pointer to some memory.
- magic elements (e.g. pointers to exported symbols):
o wayland display stores interface type pointer (first elm.)
o gbm stores pointer to its constructor (first elm.)
o x11 as a fallback (FIXME?)
