This commit makes configUSE_TRACE_FACILITY and configUSE_STATS_FORMATTING_FUNCTIONS configurable in kconfig. Test cases fro the functions enabled by the two configurations above have also been added. Test cases for the following functions have been added... - uxTaskGetSystemState() - uxTaskGetTaskNumber() - vTaskSetTaskNumber() - xEventGroupClearBitsFromISR() - xEventGroupSetBitsFromISR() - uxEventGroupGetNumber() - uxQueueGetQueueNumber() - vQueueSetQueueNumber() - ucQueueGetQueueType() Test cases for the following functions were not required... - prvListTaskWithinSingleList() - prvWriteNameToBuffer() - vTaskList()
