	above functions.
	* libpthread.map: Add names in GLIBC_2.1 section.
	* manager.c (pthread_handle_create): Implement guardsize and
	user stack.
	(pthread_free): Likewise.
	* pthread.c (pthread_create): Add new interface for changed
	pthread_attr_t.
	* sysdeps/pthread/pthread.h: Add prototypes for new functions.
