* malloc/arena.c (ptmalloc_init): Recognize MALLOC_PERTURB_ and call
mallopt appropriately. * malloc/malloc.h: Define M_PERTURB. * malloc/malloc.c (perturb_byte): New variable. (alloc_perturb, free_perturb): New macros. (_int_malloc): Before returning, overwrite the memory if this is requested. (_int_free): Overwrite freed memory if requested. (mALLOPt): Handle M_PERTURB. * test-skeleton.c: Add call to mallopt with M_PERTURB command.
