- Make activity sleep state independent of power manager wakefulness
state. The state is now entirely dependent on sleep tokens (and the
voice interactor).
- Make sleep tokens operate on a per-display basis (and convert the
keyguard to a sleep token).
- Make ActivityStackSupervisor acquire/release sleep tokens for
non-default displays when the displays are turned on/off.
- Make WindowManagerService.okToDisplay operate on a per-display basis.
