Florian Weimer 3da825ce48 malloc: Fix attached thread reference count handling [BZ #19243] 
reused_arena can increase the attached thread count of arenas on the
free list.  This means that the assertion that the reference count is
zero is incorrect.  In this case, the reference count initialization
is incorrect as well and could cause arenas to be put on the free
list too early (while they still have attached threads).

	* malloc/arena.c (get_free_list): Remove assert and adjust
	reference count handling.  Add comment about reused_arena
	interaction.
	(reused_arena): Add comments abount get_free_list interaction.
	* malloc/tst-malloc-thread-exit.c: New file.
	* malloc/Makefile (tests): Add tst-malloc-thread-exit.
	(tst-malloc-thread-exit): Link against libpthread.
