* thread.cc (pthread_mutex::pthread_mutex): Change default type

Browse Source 
to PTHREAD_MUTEX_NORMAL.
	(pthread_mutex::unlock): Return EPERM if the mutex has no owner and
	the mutex type is PTHREAD_MUTEX_ERRORCHECK, as on Linux.
	(pthread_mutexattr::pthread_mutexattr): Ditto.
	(pthread_mutex_unlock): Do not fail if mutex is a normal mutex
	initializer.
	* include/pthread.h (PTHREAD_MUTEX_INITIALIZER): Redefine as
	PTHREAD_NORMAL_MUTEX_INITIALIZER_NP.
