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