drm/i915: refactor error detection & collection
This patch refactors the existing error detection and collection code, placing most of it in i915_handle_error(). Additionally, we introduce a work queue for scheduling post-crash tasks such as generating a uevent. Using the uevent facility, userspace should be able to capture a post-mortem dump for diagnostics.
