Update.
	* pthread_attr_setschedparam.c: Don't test priority against limits
	here.  Set ATTR_FLAG_SCHED_SET flag.
	* pthread_attr_setschedpolicy.c: Set ATTR_FLAG_POLICY_SET flag.
	* pthread_create.c (__pthread_create_2_1): Copy scheduling attributes
	from parent thread to child.  If attribute is used and scheduling
	parameters are not inherited, copy parameters from attribute or
	compute them.  Check priority value.
	* pthread_getschedparam.c: If the parameters aren't known yet get
	them from the kernel.
	* pthread_setschedparam.c: Set ATTR_FLAG_SCHED_SET and
	ATTR_FLAG_POLICY_SET flag for thread.
	* sysdeps/unix/sysv/linux/internaltypes.h: Define ATTR_FLAG_SCHED_SET
	and ATTR_FLAG_POLICY_SET.

	* sysdeps/pthread/createthread.c: Use tgkill if possible.
