* malloc/arena.c (heap_info): Add mprotect_size field, adjust pad.
(new_heap): Initialize mprotect_size.
(grow_heap): When growing, only mprotect from mprotect_size till
new_size if mprotect_size is smaller. When shrinking, use PROT_NONE
MMAP for __libc_enable_secure only, otherwise use MADV_DONTNEED.
