The CoreSight testing contains sub cases, e.g. every CPU iterates the possible conntected sinks and tests the paths between the associated ETM with the found sink. Besides the per-thread testing, it also contains system wide testing and snapshot testing. To easier observe results for the sub cases, this patch introduces a new function arm_cs_report(), it outputs the result as "PASS" or "FAIL" for every sub case; and it records the error in the variable "glb_err" which is used as the final return value when exits the testing.
