Instead of creating FBOs on the GL side, the KMS EGL platform uses the
latest changes to Mesa to create an EGL surface using a GBM surface as
the native surface type. This removes some of the special vtable hooks
that the KMS platform needed because it is now much more similar to
the other platforms.

This moves all of the code specific to the Android platform out of
cogl-winsys-egl. It is completely untested apart from that it
compiles using a dummy android/native_window.h header.

The egl_surface_width/height properties in CoglDisplayEGL were
accidentally being conditionally defined depending on KMS
support. They are not necessary because CoglDisplayKMS also already
stores the width/height and this was just copied over to the EGL
dipslay.

CoglXlibDisplay just contained one member called dummy_xwin. This was
not shared outside of the respective winsys's so I don't think it
really makes sense to have a separate shared struct for it. It seems
more like an implementation detail that is specific to the winsys
because for example it may be that the EGL winsys could use the
surfaceless extension and not bother with a dummy window. This will
also make it easier to factor out the Xlib-specific data in
CoglDisplayEGL to the platform data.

Previously the Xlib renderer data was meant to be the first member of
whatever the winsys data is. This doesn't work well for the EGL winsys
because it only needs the Xlib data if the X11 platform is used. The
Xlib renderer data is now instead created on demand and connected to
the object using cogl_object_set_user_data. There is a new function to
get access to it.

Instead of having #ifdefs to hook into the normal EGL winsys, the KMS
winsys now overrides any winsys functions that it wants. Where the
winsys wants to hook into a point within a function provided by the
EGL winsys there is a EGL-platform vtable which gets set on the EGL
renderer data during renderer_connect. The KMS-specific data on all of
the structures is now allocated separately by the KMS winsys and is
pointed to by a new 'platform' pointer in the EGL data.

The #ifdefs in cogl-winsys-egl have been changed so that they
additionally check renderer->winsys_vtable->id for the corresponding
winsys ID so that multiple EGL platforms can be enabled.
The is a stop-gap solution until we can move all of the EGL platforms
into their own winsys files with overrides of the EGL vtable. However
with this approach we can move one platform at a time which will make
it easier.

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.

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.
