* malloc/hooks.c (MALLOC_STATE_VERSION): Bump.

Browse Source 
(public_sET_STATe): If ms->version < 3, put all chunks into
	unsorted chunks and clear {fd,bk}_nextsize fields of largebin
	chunks.

	* malloc/malloc.c [MALLOC_DEBUG]: Revert 2007-05-13 changes.
	* malloc/hooks.c: Likewise.
	* malloc/arena.c: Likewise.
	* malloc/malloc.c (do_check_malloc_state): Don't assert
	n_mmaps is not greater than n_mmaps_max.  This removes the need
	for the previous change.

	* malloc/Makefile (CFLAGS-malloc.c): Revert accidental
	2007-05-07 commit.
