(FORWARD2): Use __libc_pthread_functions_init instead of testing
__libc_pthread_functions.ptr_##name value.
(FORWARD_NORETURN): Add macro.
(pthread_exit): Use FORWARD_NORETURN instead of FORWARD2.
* libc_pthread_init.c (__libc_pthread_init): Set
__libc_pthread_functions_init to 1.
* pthread/pthread-functions.h (__pthread_once, __pthread_rwlock_rdlock,
__pthread_rwlock_wrlock, __pthread_rwlock_unlock, __pthread_key_create,
__pthread_getspecific, __pthread_setspecific, _cthreads_flockfile,
_cthreads_funlockfile, _cthreads_ftrylockfile): Add prototypes.
(pthread_functions): Add ptr_pthread_once, ptr_pthread_rwlock_rdlock,
ptr_pthread_rwlock_wrlock, ptr_pthread_rwlock_unlock,
ptr_pthread_key_create, ptr_pthread_getspecific, ptr_pthread_setspecific,
ptr__IO_flockfile, ptr__IO_funlockfile, ptr__IO_ftrylockfile.
(__libc_pthread_functions_init): Add variable declaration.
(PTHFCT_CALL): Add macro.
* pthread/pt-initialize.c (pthread_functions): Initialize ptr_pthread_once,
ptr_pthread_rwlock_rdlock, ptr_pthread_rwlock_wrlock, pthread_rwlock_unlock,
ptr_ptr_pthread_key_create, pthread_getspecific, ptr_pthread_setspecific,
ptr_ptr__IO_flockfile, _IO_funlockfile, ptr__IO_ftrylockfile.
