Fix pthread_mutex_t static initializers
Fix pthread_mutex_t static initializers by not leaving references to
__pthread_recursive_mutexattr.
* include/pthread/pthread.h.orig (PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP): New
macro.
* sysdeps/generic/pt-mutex-destroy.c (_pthread_mutex_destroy): Compare
mutex->attr with __PTHREAD_ERRORCHECK_MUTEXATTR and
__PTHREAD_RECURSIVE_MUTEXATTR instead of __pthread_recursive_mutexattr.
* sysdeps/generic/pt-mutex-init.c (_pthread_mutex_init): Likewise.
* sysdeps/generic/pt-mutex-timedlock.c (__pthread_mutex_timedlock_internal):
Likewise.
* sysdeps/generic/pt-mutex-transfer-np.c (__pthread_mutex_transfer_np):
Likewise.
* sysdeps/generic/pt-mutex-trylock.c (__pthread_mutex_trylock): Likewise.
* sysdeps/generic/pt-mutex-unlock.c (__pthread_mutex_unlock): Likewise.
* sysdeps/generic/pt-mutexattr.c (__pthread_errorcheck_mutexattr): New const.
* sysdeps/generic/bits/mutex-attr.h (__pthread_errorcheck_mutexattr): Declare
const.
* sysdeps/generic/bits/mutex.h (__PTHREAD_ERRORCHECK_MUTEXATTR,
__PTHREAD_ERRORCHECK_MUTEX_INITIALIZER, __PTHREAD_RECURSIVE_MUTEXATTR): New
macros.
(__PTHREAD_RECURSIVE_MUTEX_INITIALIZER): Use __PTHREAD_RECURSIVE_MUTEXATTR macro
instead of &__pthread_recursive_mutexattr.
