sched/sched/sched_getcpu.c: Implement non-standard interface.
...
If SMP is enabled this function will return the number of the CPU that the thread is running on. This is non-standard but follows GLIBC if __GNU_SOURCE is enabled. The returned CPU number is, however, worthless since it returns the CPU number of the CPU that was executing the task when the function was called. The application can never know the true CPU number of the CPU tht it is running on since that value is volatile and change change at any time.

This commit adds a new internal interfaces and fixes a problem with three APIs in the SMP configuration. The new internal interface is sched_cpu_pause(tcb). This function will pause a CPU if the task associated with 'tcb' is running on that CPU. This allows a different CPU to modify that OS data stuctures associated with the CPU. When the other CPU is resumed, those modifications can safely take place.
...
The three fixes are to handle cases in the SMP configuration where one CPU does need to make modifications to TCB and data structures on a task that could be running running on another CPU. Those three cases are task_delete(), task_restart(), and execution of signal handles. In all three cases the solutions is basically the same: (1) Call sched_cpu_pause(tcb) to pause the CPU on which the task is running, (2) perform the necessary operations, then (3) call up_cpu_resume() to restart the paused CPU.
