From: Paulo Zanoni <paulo.r.zanoni@intel.com>

For now, only connectors have it. In the future, all objects that need
properties should use it. Since the structure is referenced inside
struct drm_mode_object, we will be able to deal with object properties
without knowing the real type of the object.
