sched/hrtimer: Add callback pointer in hrtimer_start.

Browse Source 
The hrtimer is designed to replace the wdog timer in future, so it
should have the callback function in its API. The evaluation results showed there is no any
performance degradation since the CPU pipeline can hide the latency.
This commit also decoupled the rb-tree implementation with the pending
state checking.
