158ecdcfd5 pthread: Fix pthread_once to use atomic compare and set
Earlier recursive mutex was being used for this but since
SCOMPARE1 is already being saved/restored during context
switch, atomic compare and set can be used for this.

07992b08e8 [pthread] Perform init_routine execution outside of the mutex
The mutex is common across all the threads. It needn't be held across
the init_routine() call as long as the 'once' behaviour is guaranteed

Saw a deadlock case, where init_routine of one thread was waiting for
the completion of init_routine in another thread.

t2: wait for command
t1: pthread_once:
         lock once_mux
         init_routine:
               inform thread t2
               wait for signal from t2
t2: received command
         pthread_once
             lock once_mux (already held by t1)
---- Deadlock ----
