Bug detailed description:
-----------------------------
It fails on Ironlake and Sandybrisge with mesa master branch, works well on
10.1 branch,
spec_EXT_texture_array_copyteximage_1D_ARRAY and
spec_EXT_texture_array_copyteximage_2D_ARRAY also fail with same bisect commit.

Bisect shows: 234db609544ee521458ce8b648e70cffe2fda6f9 is the first bad commit.

    meta: Add an accelerated glCopyTexSubImage using glBlitFramebuffer.

    You'll note from the previous commits that there's something of a loop
    here: You call CTSI, which calls BlitFB, then if things go wrong that
    falls back to CTSI.  As a result, meta CTSI reaches over into blitfb to
    tell it "no, don't try that fallback".

    v2: Drop the _mesa_update_state(), which was only necessary due to use of
        _mesa_clip_blit() in _mesa_meta_BlitFramebuffer() in another patch
        series.
    v3: Drop an _EXT suffix I copy-and-pasted.
