确保抛出异常时，原有代理拉流对象被正常移除，后续可以更新正确url

同时暴露webrtc over tcp端口

确保emitErr只触发一次onErr回调

如果需要调用getSnap和addFFmpegSource接口，可以关闭cpu亲和性以发挥ffmpeg多核性能

空构造和析构函数替换为缺省
去除多余分号

该修改主要解决rtp级联(调用startSendRtp接口)未做gop缓存导致上级无法秒开的问题。
同时通过RingBuffer对象线程隔离的特性，实现了在断连续推场景下归属线程切换导致的线程安全问题。
用户如未使用rtp级联功能，请修改配置文件关闭GOP缓存(rtp_proxy.gop_cache=0)以便节省内存。
