[Backported from master.]

Some EGL implementations do not actually ship all Khronos-
extensions. As it turns out, the Mali 450 driver does not
include any of the following symbols, used by the
egl_mesa_platform_surfaceless.c spec test:
* eglGetPlatformDisplay
* eglCreatePlatformPixmapSurface
* eglCreatePlatformWindowSurface

The Right Thing To Do was to obtain the implementation of
these functions (via eglGetProcAddress), as is provided
by their EXT counterparts. These are guaranteed to exist
since they are required by EGL_EXT_platform_base.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+The EGL_MESA_platform_surfaceless extension was introduced not too long
+ago. Add support for it our helper.
+
+Upstream-Status: Accepted, since git 7b74602.
