* allocatestack.c (__free_stacks): Renamed from free_stacks.

	(__free_stack_cache): Removed.  Change callers to call __free_stacks.
	* init.c (nptl_freeres): New function.
	(pthread_functions): Initialize ptr_freeres to nptl_freeres.
	* pthreadP.h: Don't declare __free_stack_cache.  Declare __free_stacks.
	* sysdeps/pthread/unwind-forcedunwind.c (libgcc_s_handle): New
	variable.
	(pthread_cancel_init): Depend in libgcc_s_handle for decision to
	load DSO.  Assign last.
	(__unwind_freeres): New function.

	* allocatestack.c (__reclaim_stacks): Reset in_flight_stack later
	for better debugging.  No need to use stack_list_add here.
