	* descr.h: Define SETXID_BIT and SETXID_BITMASK.  Adjust
	CANCEL_RESTMASK.
	(struct pthread): Move specific_used field to avoid padding.
	Add setxid_futex field.
	* init.c (sighandler_setxid): Reset setxid flag and release the
	setxid futex.
	* allocatestack.c (setxid_signal_thread): New function.  Broken
	out of the bodies of the two loops in __nptl_setxid.  For undetached
	threads check whether they are exiting and if yes, don't send a signal.
	(__nptl_setxid): Simplify loops by using setxid_signal_thread.
	* pthread_create.c (start_thread): For undetached threads, check
	whether setxid bit is set.  If yes, wait until signal has been
	processed.

	* allocatestack.c (STACK_VARIABLES): Initialize them.
	* pthread_create.c (__pthread_create_2_1): Initialize pd.
