修复SDL_OpenAudio()接口可能打开失败问题

如果帧序列为SPS PPS SEI IDR，那么GOP缓存会从IDR开始，导致解码器未获取到SPS PPS从而不能秒开

参考：#2459

修复issue： #2432 

此bug由 #2448 引入，触发条件：
- 1.配置文件rtsp.directProxy设置为0
- 2.调用addStreamProxy代理rtsp流

在非直接代理情况下，PlayerProxy::_media_src为空，导致访问空指针。

配置项为http.allow_cross_domains

Add some functions for the proxy player, such as:
getting stream information (basic video/audio information)
callbacks for any connection and disconnection from the server
And now you can set delay between reconnections. See proxy player
constructor

GCC Does not explicitly include stdint. This update includes them where needed.
A very minor change that would allow GCC13 and above to compile
correctly. In newer versions, cstdint is not implicitly included, hence
it errors out during compilation for some files.

解析多层级rtmp url会丢失某些层级信息:  #2433

避免服务器端返回content-length=0时,TsPlayer不能正确释放的问题

通过whip/whep 回复http头中的Location url进行删除资源
新增delete token随机数实现删除鉴权

h265 rtp pack avoid 1387 size nal fu-a only one end packet and first satrt end not exist try fix #2425

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
