[Mesa-dev] [PATCH 07/10] gallium: add tessellation shader stage defines

[Luca Barbieri]

Don't add the pipe_screen/pipe_context members yet, since no actual
implementation is planned right now.

DirectX 11 calls these "hull" and "domain" shaders.

Since we are already using "fragment" instead of "pixel", and the
OpenGL naming is much clearer, use it.

They are abbreviated to "tessctrl" and "tesseval" for brevity.
