[Mesa-dev] [PATCH v2 0/6] Enable GL_OES_geometry_shader for OpenGL ES 3.1

[Marta Lofstedt]

After I was able to remove the ARB_geometry_shader4
extension I have now rebased my OES_geometry_shader patches.

In order to avoid confusion I send V2 for all patches,
i.e. all of my old OES_geometry_shader patches are now obsolete.

The patches are available here:
https://github.com/MartaLo/mesa/tree/gl_oes_geometry_shader_v2

Changes for V2:
gles2: Update gl2ext.h to revision: 32902:
Updated to the latest gl2ext.h

glapi: add GL_OES_geometry_shader extension:
After comments from Ilia I squashed my previous,
http://patchwork.freedesktop.org/patch/60228/
and
http://patchwork.freedesktop.org/patch/60225/
patches.

glsl: add support for GL_OES_geometry_shader:
After comments from Ilia, added support for glsl version 3.2

mesa: enable enums for OES_geometry_shader:
This needed some work after the ARB_geometry_shader4 was removed.
After a comment from Ilia, I moved all OES_geometry_shader enums
to GL_CORE and GLES31.
I created new EXTRA_EXT for enums that OES_geometry_shader has in
common with ARB_shader_storage_buffer_object, ARB_gpu_shader5 and
ARB_viewport_array.
In my previous patch for the ARB_viewport_array enum
LAYER_PROVOKING_VERTEX, I added an extra that checked
ARB_viewport_array or OES_geometry_shader. But since
ARB_viewport array requires EXT_geometry_shader4, I believe it is
better to check if some version of geometry shader is available.
The dependency for ARB_viewport_array on geometry shader should
be fixed in a another patch.
Also, we may need to discuss if the full ARB_viewport_array
should be exposed under GLES 3.1.

I also renamed the GS4 EXTRA_EXT stuff to only GS.
I should have done that when I removed the ARB_geometry_shader4

the rest of the changes are simple rebases.
