[PATCH] hrtimer: create generic sleeper
The removal of the data field in the hrtimer structure enforces the
embedding of the timer into another data structure. nanosleep now uses a
private implementation of the most common used timer callback function
(simple task wakeup).
In order to avoid the reimplentation of such functionality all over the
place a generic hrtimer_sleeper functionality is created.
