1. chunk overhead区增加两个字段usize和state，分别记录实际占用的payload的大小以及当前chunk的状态。
其中chunk的状态包括是否分配给用户以及是否被下毒。下毒指的是在chunk除有效payload（即用户实际使用
的内存）外的内存中填充进随机生成的数据。在malloc/free时检测这些区域即可实现对溢出以及UAF的校验。

2. 为了提高性能，并不会对所有chunk下毒，而是每POISON_COUNT_DOWN_BASE次malloc/free时进行一次下毒。

空闲块释放后，不会立即进入待分配队列或归还给系统，而是被放入一个隔离区。
当隔离区满后，其中的空闲块会被放入待分配队列或归还物理内存给操作系统。

1. 指针混淆:
   对空闲chunk的双向链表指针next、prev进行混淆。具体为将该指针与一个key做异或操作。
   不同的bin拥有不同的key，key通过随机数生成器生成。
2. safe unlink:
   在unbin操作时校验双向链表的有效性，即检查双向链表中前一项和后一项的指向当前chunk
   的指针是否正常，否则终止进程。

这两个功能均可通过MALLOC_FREELIST_HARDENED宏开关
这个宏可以通过编译框架直接开关（在编译命令后增加 --gn-args "musl_secure_level=1"打开）
