AddListen

@param addrCtx: 

 LocalAddrCtx.IsHttps 是否为https。
	注意，如果要为相同的路由同时绑定http和https，那么应该调用该函数两次，分别将该参数设置为true和false。
	LocalAddrCtx.Addr 监听地址，内部会为其建立监听。
	http和https不能够使用相同的地址。
	注意，多次调用，允许使用相同的地址绑定不同的`pattern`。
	LocalAddrCtx.CertFile ...
	LocalAddrCtx.KeyFile ...
	LocalAddrCtx.Network 如果为空默认为NetworkTcp="tcp"。

@param pattern: 必须以`/`开始，并以`/`结束。 

注意，如果是`/`，则在其他所有pattern都匹配失败后，做为兜底匹配成功。
相同的pattern不能绑定不同的`handler`回调函数（显然，我们无法为相同的监听地址，相同的路径绑定多个回调函数）。

	//
	// TODO(chef): 是否应该严格保证：获取到关闭消息后，后续不应该再有该session的回调上来
	//
	// @return 一般关闭有以下几种情况：
	//         - 对端关闭，此时error为EOF
	//         - 本端底层关闭，比如协议非法等，此时error为具体的错误值
