Update.

	* descr.h: Define CANCELING_BIT and CANCELING_BITMASK.  Introduce
	after CANCELTYPE_BIT, move the other bits up.  Update CANCEL_RESTMASK.
	* init.c (sigcancel_handler): Also set CANCELING_BITMASK bit in newval.
	* pthread_cancel.c (pthread_cancel): Likewise.  Also set CANCELING_BIT
	if asynchronous canceling is enabled.
	* pthread_join.c (pthread_join): When recognizing circular joins,
	take into account the other thread might be already canceled.
	* Makefile (tests): Add tst-join5.
	* tst-join5.c: New file.
