intel: Add support for GPU reset status query ioctl
I would have just used the drmIoctl interface directly in Mesa, but the ioctl needs some data from the drm_intel_context that is not exposed outside libdrm. v2: Update based on Mika's kernel work. v3: Fix compile failures from last-minute typos. Sigh.
