	to manager thread.
	(__pthread_handles_num): Initialize to 2.
	(__pthread_manager): Use INIT_THREAD_SELF with two arguments.
	(pthread_start_thread): Likewise.
	(pthread_handle_create): Start search for free slot at entry 2.
	Initialize new fields p_self and p_nr.
	Call __clone with CLONE_PTRACE if available.
	(pthread_free): Call FREE_THREAD_SELF if available.
	* pthread.c (__pthread_initial_thread): Initialize new fields.
	(__pthread_manager_thread): Likewise.
	(__pthread_initialize_manager): Call __clone with CLONE_PTRACE.

	* cancel.c: Use THREAD_GETMEM and THREAD_SETMEM to access the
	elements of the thread descriptor.
	* condvar.c: Likewise.
	* errno.c: Likewise.
	* join.c: Likewise.
