/**
 * 解码CMEM的dump文件, 输出为key作为文件名的txt文件,value作为其文本内容.

 * @version  2017.04.27 更新了解析规则, 对方发来的数据带有了4个字节的类型信息如果是0则没有压缩,2采用压缩.
 *           这比原来的数据友好多了, 全部数据完美解析.

 *      CMEM有两中模式二进制和字符串.一般都用字符串模式,概因效率相差不多.
 *      本脚本内解码算法亦以字符串模式为基础.
 *      原理: php写入Memcache的字符串对象(c格式的即字节数组)将会被转换为hex字符串
 *      再写入memcache, memcache的压缩标志 MEMCACHE_COMPRESSED 指定使用zlib压缩.
 *      如果自己的cmem库中使用了压缩,那么需要在将hex还原为字符串后再解压缩一遍还原为
 *      原来的数组.
 *      addition: 即便使用了 MEMCACHE_COMPRESSED 标志位, memcache规定,
 *      压缩比大于0.8的不采用压缩value
 *           将不被压缩. 因此,下文代码中针对这一特殊规定做了处理.
