Provide local connection pool like java

• PHP 5.3 + (no zts)
• linux 2.6+
• pdo and redis extension install

phpize=>./configure=>make install=>echo "extensions=xx/connect_pool.so">php.ini

##Technical characteristics:

• After each time fetchAll (set/get) call release() method, release the connection to the pool, avoid that the script jammed causing connection occupy high problem.
• The maximum and minimum number of connections configuration support.
• Support small pressure automatic recovery connection.
• Support graceful restart (reload).
• Do a lot of optimization, although the request through the connection pool process forward, but no loss of QPS.
• When the connection use out,support queue.
• Simple! just change the new method and add release function (see demon),you used the tcp pool.
• The connection proxy will start the ping process to monitor down list, if available will reflect to the return value of the get_disable_list(), use this function you can do some fun things,like LB.

step 1 move the pool.ini file to /etc/ and modify it as you need.

step 2 start the pool_server process：

```support "start" "stop" "restart" "reload"

step 3 modify you php script:

##API
get_disable_list($pdo_config,CP_DEFAULT_PDO_PORT);// get the pdo disable ips;
get_disable_list($redis_conf,CP_DEFAULT_REDIS_PORT); // get the redis disable ips;

- first param is you ip list.
- if the first param changed,the disable list will be clear.
- this function will return the fail ips.

## 提示
- pool_server 必须以root用户启动
- redis不支持pub/sub方法
