Gregory Nutt d8cf3bfe25 Rethink some of the conditional logic of commit 1ac9558460: If the Critical Section Monitor enabled, that that platform-specific timer should be used to measure interrupt processing time, no matter what.

sched/clock/ timekeeping: Use clock_basetime() to initialize g_clock_wall_time to get the best initial RTC value and initialize g_clock_last_counter too since the hardware may not start counting from zero.

init

Assertions: Identify the running task correctly when dumping task state information. It takes time to switch to the target task after g_readytorun has been modified. If panic/assert happen during this period, the dump will contain the incorrect and confusing information due to the difference between the real running task and the return value of this_task(). This change resolve this problem by adding g_running_task to track the real running task through the context switch.

sched

sched/irq and sched/sched: Measurement of interrupt handler duration used to be available only in Tickless mode since it used the high resolution Tickless timer to measure interrupt time. This commit adds CONFIG_SCHED_IRQMONITOR_GETTIME which, if enabled, will force the interrupt duration caculation to use the same high-resolution, platform-specific timer as is used with the Critical Section Monitor. This leads to two improvements: (1) You can now measure interrupt duration in non-Tickless mode, and (2) in either mode, the interrupt duration and the critical section measures will use the same high-resulotion timer and should, therefore, never be any descripancy due to different clock sources.
