sched note: printf API example
test API:
void sched_note_string(FAR const char *buf);
void sched_note_dump(uint32_t module, uint8_t event,
FAR const void *buf, size_t len);
void sched_note_printf(FAR const char *fmt, ...) printflike(1, 2);
void sched_note_bprintf(uint32_t module, uint8_t event,
FAR const char *fmt, ...) printflike(3, 4);
https://github.com/apache/incubator-nuttx/pull/4963
suggestion:
1. add "&" after the command when running this example.
2. must enable SCHED_INSTRUMENTATION_DUMP, and that enable
CONFIG_SYSTEM_TRACE can help you view log.
