Linux and char* for FreeBSD. (Adam Jackson)

On EGL 1.4, one had to check for the existence of EGL_EXT_platform_base
before querying the eglGetPlatformDisplayEXT() and
eglCreatePlatformWindowSurfaceEXT() symbols, to then use them if the
EGL_EXT_platform_* extension for the given platform was exposed.
Since EGL 1.5, the platform functionality was made core, which means we
can obtain the symbols unconditionally, but we can't know the EGL
version before having created a display, at which point we've already
done a platform selection by passing an EGLNativeDisplay. The
EGL_KHR_platform_* extensions thus are used by clients to know whether
it's safe or not to dlsym() the EGL 1.5 symbols.
This commit adds those extensions when the given platform is enabled.

For GLVND reasons the client/platform extensions strings should be
split. While in the non GLVND case they're one big string.
Currently we handle this distinction at run-time for not obvious reason.
Adding additional code and complexity.
Swap those with a few well placed #if USE_LIBGLVND guards.
As a side result this removes a minor memory leak due to the
concatenation in the non GLVND case.

On platforms without mincore(), _eglPointerIsDereferencable()
currently just checks whether p != NULL. This is not sufficient:
In the Wayland platform code (i.e., in get_wl_surface_proxy()),
_eglPointerIsDereferencable() is called on the version field
of `struct wl_egl_window` which is 3 on current versions of
Wayland. This causes a segfault when trying to dereference p.
Fix this behavior by assuming that the first page of the
process is never dereferencable.

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

devices. Each one exposing the respective extension string.

mincore() returns 0 on success, and -1 on failure. The last parameter
is a vector of bytes with one entry for each page queried. mincore
returns page residency information in the first bit of each byte in the
vector.
Residency doesn't actually matter when determining whether a pointer is
dereferenceable, so the output vector can be ignored. What matters is
whether mincore succeeds. See:

The new interface mostly just sits on top of the existing library.
The only change to the existing EGL code is to split the client
extension string into platform extensions and everything else. On
non-glvnd builds, eglQueryString will just concatenate the two strings.
The EGL dispatch stubs are all generated. The script is based on the one
used to generate entrypoints in libglvnd itself.
v2: [Kyle]
- Rebased against master.
- Reworked the EGL makefile to use separate libraries
- Made the EGL code generation scripts work with Python 2 and 3.
- Change gen_egl_dispatch.py to use argparse for the command line arguments.
- Assorted formatting and style cleanup in the Python scripts.

Mesa's set of supported platform extensions depends on the autoconf
option --with-egl-platforms=foo,bar,baz. If --with-egl-platforms lacks
foo, then eglGetPlatformDisplay(EGL_PLATFORM_FOO, ...) unconditonally
fails.
So, if --with-egl-platforms lacks foo, then remove
EGL_VENDOR_platform_foo from the EGL client extension string.

Enable EGL_EXT_platform_base and the Linux platform extensions layered
atop it: EGL_EXT_platform_x11, EGL_EXT_platform_wayland,

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

Replace all occurences of the macro with its expansion.
It seems that the macro intended to provide cross-platform static mutex
intialization. However, it had the same definition in all pre-processor
paths:
#define _EGL_DECLARE_MUTEX(m) _EGLMutex m = _EGL_MUTEX_INITIALIZER
Therefore this abstraction obscured rather than helped.

Driver loading is now splitted into two stages. In the first stage, an
_EGLModule is created for each driver: user driver, default drivers, and
all files in the search directories that start with "egl_". Modules are
not loaded at this stage.
In the second stage, each module is loaded to initialize a display. The
process stops at the first module that can initialize the display.
If eglGetProcAddress is called before eglInitialize, the same code path
will be taken to find the first module that supports
EGL_DEFAULT_DISPLAY. Because we do not want to initialize the display,
drv->Probe is used instead in this case.
When there is no user driver or any matching display drivers we fall
back to the default driver. This patch lets us have a list of default
drivers instead of just one. The drivers are loaded in turn and we
attempt to initialize the display. If it fails we unload the driver
and move on to the next one.
Compared to the display driver mechanism, this avoids loading a number
of drivers and then only using one. Also, we call Initialize to see
if the driver will work instead of relying on Probe. To know for sure
that a driver will work, Probe really have to do a full Initialize, so
we will just use Initialize directly.
As a result, EGL_NONE is no longer a valid client API. And it is
possible that no config supports the current bound API.

Driver is chosen and preloaded when eglGetDisplay is called. Later when
eglInitialize is called, the same driver is matched to initialize the
display. Also, add new, but unused, hooks to EGLDriver to allow a
driver to probe a display or unload itself.
