The name of the structure drm_atomic_state is confusing. Let's add an
entry to our todo list to rename it.

Rename drm_atomic_state
-----------------------
The KMS framework uses two slightly different definitions for the ``state``
concept. For a given object (plane, CRTC, encoder, etc., so
``drm_$OBJECT_state``), the state is the entire state of that object. However,
at the device level, ``drm_atomic_state`` refers to a state update for a
limited number of objects.
The state isn't the entire device state, but only the full state of some
objects in that device. This is confusing to newcomers, and
``drm_atomic_state`` should be renamed to something clearer like
``drm_atomic_commit``.
In addition to renaming the structure itself, it would also imply renaming some
related functions (``drm_atomic_state_alloc``, ``drm_atomic_state_get``,
``drm_atomic_state_put``, ``drm_atomic_state_init``,
``__drm_atomic_state_free``, etc.).
