Update.
	* pthreadP.h: Mark declarations of __find_in_stack_list, __free_tcb,
	and __deallocate_stack with internal_function.
	* pthread_create.c: Adjust definitions appropriately.
	* allocatestack.c: Likewise.

	* pthread_join.c: Add one more __builtin_expect.
	* pthread_timedjoin.c: Likewise.

	* pthread_getspecific.c (__pthread_getspecific): Clear data->data
	not data of sequence number does not match.
	Add one __builtin_expect.
