i965: Add field intel_mipmap_tree::disable_aux_buffers
The new field disables allocation of auxiliary buffers, such as the HiZ buffer and MCS buffer. This is useful for sharing the miptree bo with an external client that doesn't understand auxiliary buffers. We need this field to safely render to a buffer that was imported with EGL_EXT_image_dma_buf_import, because EGL does not yet have extensions to manage flushing and invalidating auxiliary buffers. Nothing yet enables this field. That's left to follow-up patches. Testing: - Tested on Ivybridge Chromebook Pixel with WebGL Aquarium and YouTube. - No Piglit regressions on Broadwell with `piglit run -p gbm tests/quick.py`.
