mesa: add fbo/texture support for ARB_texture_cube_map_array (v2)
This adds the mesa core + texture + fbo support for the
texture cube map array extension.
v2:
add comment to _mesa_num_tex_faces related to cube map arrays (Brian)
drop wrong comment cut-n-paste (Brian)
fix / 6 maximum check issue (Kenneth)
coalsece some array case statements (Kenneth)
