Subject: [PATCH 1/5] clutter/stage: Make clutter_stage_schedule_update()
always schedule
We could call clutter_stage_schedule_update() and it wouldn't actually
schedule anything, as the master frame clock only tries to reschedule if
1) there is an active timeline, 2) there are pending relayouts, 3) there
are pending redraws, or 4) there are pending events. Thus, a call to
clutter_stage_schedule_update() didn't have any effect if it was called
at the wrong time.
Fix this by adding a boolean state "needs_update" to the stage, set on
clutter_stage_schedule_update() and cleared on
_clutter_stage_do_update(), that will make the master clock reschedule
an update if it is TRUE.

Subject: [PATCH 2/5] clutter/stage: Make clutter_stage_schedule_update()
public API
It's effectively used by mutter by abusing a ClutterTimeline to scedule
updates. Timelines are not really suited in places that is done, as it
is really just about getting a single new update scheduled whenever
suitable, so expose the API so we can use it directly.

Subject: [PATCH 3/5] wayland/actor-surface: Always store away frame callbacks
on commit
We're expected by MetaWaylandSurface to always pick the frame callbacks
out from the pending state when committing (applying) so that no frame
callbacks are unaccounted for. We failed to do this if our actor for
some reason (e.g. associated window was unmanaged) was destroyed. To
handle this situation better, store away the frame callbacks until we
some later point in time need to pass them on forward.
