i965: Add support for ARB_copy_image

This, together with the meta path, provides a complete implemetation of
ARB_copy_image.

v2: Add a fallback memcpy path for when the texture is too big for the
    blitter
v3: Properly support copying between two places on the same texture in the
    memcpy fallback
v4: Properly handle blit between the same two images in the fallback path
v5: Properly handle blit between the same two compressed images in the
    fallback path
v6: Fix a typo in a comment
