注意事项：

有两个库 zookeeper_st和zookeeper_mt，我们尽量都用zookeeper_mt，并且使用的时候加上-DTHREADED，zookeeper_st只支持异步api，并且需要自己处理事件和回调，以下是官方的说明

The package includes two shared libraries: zookeeper_st and zookeeper_mt. The former only provides the asynchronous APIs and callbacks for integrating into the application's event loop. The only reason this library exists is to support the platforms were a  pthread  library is not available or is unstable (i.e. FreeBSD 4.x). In all other cases, application developers should link with zookeeper_mt, as it includes support for both Sync and Async API.

In order to be able to use the ZooKeeper API in your application you have to remember to

1. Include ZooKeeper header: #include

2. If you are building a multithreaded client, compile with -DTHREADED compiler flag to enable the multi-threaded version of the library, and then link against against thezookeeper_mt library. If you are building a single-threaded client, do not compile with -DTHREADED, and be sure to link against the zookeeper_st library.
