The surfaceless extension that Mesa advertises has been renamed to
EGL_KHR_surfaceless_context instead of a separate extension for the
GLES, GLES2 and GL APIs and the new extension has been ratified by
Khronos. Therefore the KMS backend no longer runs against Mesa master.
We could just rename the extension we check for, however Weston (the
sample Wayland compositor) has switched to just creating a dummy GBM
surface and not using the surfaceless extension at all. We should
probably do the same thing.
Using the surfaceless extension could be a good idea but we don't
really need to rely on it for KMS and we would want to do it for all
EGL backends, not just the KMS backend.

(cherry picked from commit d4f22f8cb013d417c99ba03924538924191c2fe6)
There are three separate EGL_KHR_surfaceless_* extensions depending on
which GL API is being used so we should probably check the right one
depending on which driver Cogl has selected.

The compositor side wayland support enabling us to create textures from
wayland buffers needed updating since visuals were removed from the
wayland protocol.
This also fixes the #ifdef guards for the bind_wayland_display extension
in cogl-winsys-egl-feature-functions.h since it was mistakenly checking
that client-side wayland support had been enabled which won't be the
case.

This adds a check for the EGL_KHR_surfaceless_opengl extension which we
depend on for being able to MakeCurrent (NO_SURFACE) as well as create a
context without and EGLConfig.

cogl-winsys-egl-feature-functions.h was unconditionally depending on the
struct wl_display type being defined. This guards the check for the
"WL_bind_wayland_display" extension with
#ifdef COGL_HAS_EGL_PLATFORM_WAYLAND_SUPPORT

This adds internal API to be able to wrap a wayland buffer as a
CoglTexture2D. There is a --enable-wayland-egl-server option to decide
if Cogl should support this feature and potentially any EGL based winsys
could support this through the EGL_KHR_image_base and
EGL_WL_bind_display extensions.
By using the EGL_KHR_image_base/pixmap extensions this adds support for
wrapping X11 pixmaps as CoglTexture2D textures. Clutter will
automatically take advantage of this if using the
ClutterX11TexturePixmap actor.
This adds an internal texture_2d constructor that can wrap an EGLImage
as a CoglTexture2D. The plan is to utilize this for texture-from-pixmap
support with EGL as well as creating textures from wayland buffers.
As was recently done for the GLX window system code, this commit moves
the EGL window system code down from the Clutter backend code into a
Cogl winsys.
Note: currently the cogl/configure.ac is hard coded to only build the GLX
winsys so currently this is only available when building Cogl as part
of Clutter.
