When stopping the stream, it will wait for the HTTP Streaming to exit.
If the HTTP Streaming goroutine hangs, it will not exit automatically.
```cpp
void SrsHttpStreamServer::http_unmount(SrsRequest* r)
{
SrsUniquePtr<SrsLiveStream> stream(entry->stream);
if (stream->entry) stream->entry->enabled = false;
srs_usleep(...); // Wait for about 120s.
mux.unhandle(entry->mount, stream.get()); // Free stream.
}
srs_error_t SrsLiveStream::serve_http(ISrsHttpResponseWriter* w, ISrsHttpMessage* r)
{
err = do_serve_http(w, r); // If stuck in here for 120s+
alive_viewers_--; // Crash at here, because stream has been deleted.
```
We should notify http stream connection to interrupt(expire):
```cpp
void SrsHttpStreamServer::http_unmount(SrsRequest* r)
{
SrsUniquePtr<SrsLiveStream> stream(entry->stream);
if (stream->entry) stream->entry->enabled = false;
stream->expire(); // Notify http stream to interrupt.
```
Note that we should notify all viewers pulling stream from this http
stream.
Note that we have tried to fix this issue, but only try to wait for all
viewers to quit, without interrupting the viewers, see
https://github.com/ossrs/srs/pull/4144

I did some preliminary code inspection. The two playback endpoints share
the same `SrsLiveStream` instance. After the first one disconnects,
`alive_` is set to false.
```
alive_ = true;
err = do_serve_http(w, r);
alive_ = false;
```
In the `SrsHttpStreamServer::http_unmount(SrsRequest* r)` function,
`stream->alive()` is already false, so `mux.unhandle` will free the
`SrsLiveStream`. This causes the other connection coroutine to return to
its execution environment after the `SrsLiveStream` instance has already
been freed.
```
// Wait for cache and stream to stop.
int i = 0;
for (; i < 1024; i++) {
if (!cache->alive() && !stream->alive()) {
break;
}
srs_usleep(100 * SRS_UTIME_MILLISECONDS);
}
// Unmount the HTTP handler, which will free the entry. Note that we must free it after cache and
// stream stopped for it uses it.
mux.unhandle(entry->mount, stream.get());
```
`alive_` was changed from a `bool` to an `int` to ensure that
`mux.unhandle` is only executed after each connection's `serve_http` has
exited.

## Describe ##
http_remux feature support config `has_audio`, `has_video` &
`guess_has_av` prop.
282d94d7bb/trunk/src/app/srs_app_http_stream.cpp (L630-L632)
Take `http_flv` as example, `srs` can accept both RTMP streams with only
audio, only video or both audio and video streams. It is controlled by
above three properties.
But `guess_has_av` is not implemented by `http_ts`. The problem is that
if I want publish a RTMP stream with audio or video track, the
`has_audio` and `has_video`, which are default true/on, must to be
config to match the RTMP stream, otherwise the `mpegts.js` player can't
play the `http-ts` stream.
## How to reproduce ##
1. `export SRS_VHOST_HTTP_REMUX_HAS_AUDIO=on; export
SRS_VHOST_HTTP_REMUX_HAS_VIDEO=on; export
SRS_VHOST_HTTP_REMUX_GUESS_HAS_AV=on; ./objs/srs -c
conf/http.ts.live.conf`
2. publish rtmp stream without video: `ffmpeg -re -stream_loop -1 -i
srs/trunk/doc/source.200kbps.768x320.flv -vn -acodec copy -f flv
rtmp://localhost/live/livestream`
3. open chrome browser, open
`http://localhost:8080/players/srs_player.html?schema=http`, go to
`LivePlayer`, input URL: `http://localhost:8080/live/livestream.ts`,
click play.
4. the `http://localhost:8080/live/livestream.ts` can not play.
## Solution ##
Let `http-ts` support `guess_has_av`, `http-flv` already supported. The
`guess_has_av` default value is ture/on, so the `http-ts|flv` can play
any streams with audio, video or both.

1. Add live benchmark support in srs-bench, which only connects and
disconnects without any media transport, to test source creation and
disposal and verify source memory leaks.
2. SmartPtr: Support cleanup of HTTP-FLV stream. Unregister the HTTP-FLV
handler for the pattern and clean up the objects and resources.
3. Support benchmarking RTMP/SRT with srs-bench by integrating the gosrt
and oryx RTMP libraries.
4. Refine SRT and RTC sources by using a timer to clean up the sources,
following the same strategy as the Live source.

Security is the built-in IP whitelist feature of SRS, which allows and
denies certain IP and IP range users. Previously, it only supported
RTMP, but this PR now supports HTTP-FLV, HLS, WebRTC, SRT, and other
protocols.
See https://ossrs.io/lts/en-us/docs/v6/doc/security as example.
