Since obj->frontbuffer is no longer protected by the struct_mutex, as we
are processing the execbuf, it may be removed. Mark the
intel_frontbuffer as rcu protected, and so acquire a reference to
the struct as we track activity upon it.

drm/i915: Extract intel_frontbuffer active tracking2019-08-16T08:51:11+00:00Chris Wilsonchris@chris-wilson.co.uk2019-08-16T07:46:35+00:00urn:sha1:8e7cb1799b4f8bde3e7d9c80bf689e5408add271
Move the active tracking for the frontbuffer operations out of the
i915_gem_object and into its own first class (refcounted) object. In the
process of detangling, we switch from low level request tracking to the
easier i915_active -- with the plan that this avoids any potential
atomic callbacks as the frontbuffer tracking wishes to sleep as it
flushes.

drm/i915: move modesetting core code under display/2019-06-17T08:48:32+00:00Jani Nikulajani.nikula@intel.com2019-06-13T08:44:16+00:00urn:sha1:df0566a641f959108c152be748a0a58794280e0e
Now that we have a new subdirectory for display code, continue by moving
modesetting core code.
display/intel_frontbuffer.h sticks out like a sore thumb, otherwise this
is, again, a surprisingly clean operation.
v2:
- don't move intel_sideband.[ch] (Ville)
- use tabs for Makefile file lists and sort them
