The idea is to be able to match a driver using the following order
try egl_gallium with hw renderer
try egl_dri2
try egl_gallium with sw renderer
try egl_glx
given the module list
egl_gallium
egl_dri2
egl_glx
For that, UseFallback initialization option is added. The module list
is matched twice: with the option unset and with the option set. In the
first pass, egl_gallium skips its sw renderer and egl_glx rejects to
initialize since UseFallback is not set. In the second pass,
egl_gallium skips its hw renderer and egl_dri2 rejects to initialize
since UseFallback is set. The process stops at the first driver that
initializes the display.
Reorder/rename and document the fields that should be set by the driver during
initialization. Drop the major/minor arguments from drv->API.Initialize.
These extensions allow an application to make a context current by
passing EGL_NO_SURFACE for the write and read surface in the call to
eglMakeCurrent. The motivation is that applications that only want to
render to client API targets (such as OpenGL framebuffer objects)
should not need to create a throw-away EGL surface just to get a
current context.
Merge multiple egl_<platform>_<pipe>.so into a single
egl_gallium_<pipe>.so. The environment variable EGL_PLATFORM is now
used to modify the return value of _eglGetNativePlatform.
The extension defines eglGetDRMDisplay that creates an EGLDisplay from a
DRM fd. Calling eglCreateWindowSurace or eglCreatePixmapSurface with
such displays will generate EGL_BAD_NATIVE_WINDOW or
EGL_BAD_NATIVE_PIXMAP.
This commit introduces type-safe platform displays internally. A
platform display consists of a generic pointer and an enum that
specifies the platform.
An EGLDisplay is created from a platform display. Native displays
become platform displays whose platform is determined by
_eglGetNativePlatform(). Platform windows and pixmaps may also be
introduced if needed.
This extension allows a color buffer to be used for both rendering and
texturing. EGL allows the use of color buffers of pbuffer drawables
for texturing, this extension extends this to allow the use of color
buffers of pixmaps too.
This extension adds a new function which provides an alternative to
eglSwapBuffers. eglSwapBuffersRegionNOK accepts two new parameters in
addition to those in eglSwapBuffers. The new parameters consist of a
pointer to a list of 4-integer blocks defining rectangles (x, y,
width, height) and an integer specifying the number of rectangles in
the list.
It was added to skip checking EGLDisplay, EGLSurface, and etc. It is
never defined and the spec does not allow the checks to be skipped.
Remove it for good.
Add missing attributes and use correct types in _EGLSurface. Remove
ifdef tests that serve no purpose. Update _eglQuerySurface and
_eglSurfaceAttrib for missing queries and checks.
Add support EGL_KHR_vg_parent_image and EGL_KHR_gl_*. This is as simple
as adding some flags that can be enabled. Individual drivers need to
implement the extensions before enbaling the flags.
The driver pointer of the display was used to decide whether a display
is initialized. Use a boolean for that purpose allows accessing the
driver of an uninitialized display.
An unlinked resource may still be a current resource such as current
surfaces. There might still be a need to know which display the
unlinked resource belongs to.
Make it similiar to how contexts and surfaces are looked up. It should
be slightly faster, and work better with multiple displays.

libX11 is used to determine the screen number, which is in turned used
to determine the DRI driver. However, the sysfs interface for
determining the DRI driver is gone, and no working driver depends on
this mechanism.
Display string parsing is moved to a new function,
_eglSplitDisplayString.

Move some fields of _EGLDriver to _EGLDisplay. It also becomes
unnecessary to pass _EGLDisplay to drivers when _eglMain is called.

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.

The motivation is so that drivers do not need to look up and check for
bad display, context, and etc. It also becomes unnecessary for drivers
to call the link functions.
This commit makes eglapi.[ch] do the lookup and check. As a result, the
driver API is overhauled, and almost all sources and drivers need
update. The updates are mainly find and replace with human brains.

Casting an unsigned int to or from a pointer directly gives warnings on
x86-64. Add wrappers to silence the warnings.
