hrtimer_setup() and hrtimer_setup_on_stack() have been introduced to
replace hrtimer_init() and hrtimer_init_on_stack(). To keep the names
consistent, also introduce hrtimer_setup_sleeper_on_stack(). The old name
hrtimer_init_sleeper_on_stack() will be removed as soon as all of its users
have been updated.
