d7f02a8cb6 sched: change pthread_mutex implementation from sem to mutex 
Since pthread_mutex is implemented by sem, it is impossible to see in ps who holds the lock and causes the wait.
Replace sem with mutex implementation to solve the above problems

b6693065e7 pthread_once: g_lock may lead deadlock 
For programs with the dependencies logic in pthread_once callback , using global locks may cause deadlock:

task A
pthread_once()
|
|-> nxrmutex_lock(&g_lock);
 -> init_routine(); // callback to wait task B
                                                  task B
                                                  pthread_once()
                                                  |
                                                   ->nxrmutex_lock(&g_lock); // Deadlock
                                                   ->init_routine(); // hold resource to wake up task A
