From: Tvrtko Ursulin tvrtko.ursulin@intel.com
Make GEM contexts keep a reference to i915_drm_client for the whole of of their lifetime which will come handy in following patches.
v2: Don't bother supporting selftests contexts from debugfs. (Chris) v3 (Lucas): Finish constructing ctx before adding it to the list v4 (Ram): Rebase. v5: Trivial rebase for proto ctx changes. v6: Rebase after clients no longer track name and pid.
