[Piglit] [PATCH 2/8] arb_direct_state_access: New test for GetCompressedTextureImage.

v2: Added increased error checking
Review from Ian Romanick and Ilia Mirkin:
- Compat context 20 (and remove check for ARB_texture_cube_map)
- Change global_pass from GL_boolean to bool
- Clean up the texture in upload_subtest
- Restructure download commands to simplify use_pbo logic
- Use separate pack and unpack pbos
I have not applied the pre-emptive R-b's because this patch series adds a new
getteximage-targets test, and, because the tests are so similar, it makes
sense to have the whole thing reviewed and pushed as a big chunk.
