[Piglit] [PATCH] Test basic behavior of clip flags.

This test verifies the following basic behaviors of the GL_CLIP_PLANEi
flags:
- There are exactly MAX_CLIP_PLANES of them, and trying to access a
nonexistent flag produces a GL_INVALID_ENUM error.
- They default to false.
- Their behavior under glGetBooleanv, glIsEnabled, glEnable, and
glDisable is consistent.
Tested on the nVidia proprietary Linux driver.
