6e0ba2bed5 sched/note: add support of trace section mark 
The implementation of this feature is based on android systrace:

https://source.android.com/devices/tech/debug/ftrace

Application developers are more concerned about the performance of
the specified application section,
added two APIs to implement performance measurement:

void sched_note_begin(uintptr_t ip, FAR const char *buf);
void sched_note_end(uintptr_t ip, FAR const char *buf);
or
SCHED_NOTE_BEGIN();  /* defined to sched_note_begin(_THIS_IP_, __FUNCTION__) */
SCHED_NOTE_END();    /* defined to sched_note_end(_THIS_IP_, __FUNCTION__) */

e781787cb9 sched/critmonitor: remove the assertion if counter == 0 
Perf timer interface generally uses the hardware cycle counter
provided by the arch chip directly(such as DWT_CYCCNT(cortex-m)),
CYCCNT is a free running counter and counting upwards.
It wraps around to 0 on overflow.

76b2f7199d sched: fix the bug of task's tmeslice 
The BUG is as follow:
 1. Suppose there are two ready tasks t1 and t2 have the same priority, and t1 is the running.
 2. A new, higher priority task t0 (such as hpwork) is ready, then switch to t0.
 3. After t0 is suspended, then switch to t1 and reset the t1's timeslice.
 4. goto 2
The t2 will have no chance to run.
