Support include empty config file. v5.0.173 (#3768)
SRS supports including another configuration in the include package.
When generating configurations, we can only generate the changed
configurations, while the unchanged configurations are in the fixed
files, for example:
```nginx
listen 1935;
include server.conf;
```
In `server.conf`, we can manage the changing configurations with the
program:
```nginx
http_api { enabled on; }
```
However, during system initialization, we often create an empty
`server.conf`, and the content is generated only after the program
starts, so `server.conf` might be an empty file. This also makes it
convenient to use a script to confirm the existence of this file:
```bash
touch server.conf
```
Currently, SRS does not support empty configurations and will report an
error. This PR is to solve this problem, making it more convenient to
use include.

## Usage
Please refer to the [Getting Started ](https://ossrs.io/lts/en-us/docs/v5/doc/getting-started ) or [中文文档：起步 ](https://ossrs.net/lts/zh-cn/docs/v5/doc/getting-started ) guide.
To build SRS from source:
```
git clone -b 5.0release https://gitee.com/ossrs/srs.git & &
cd srs/trunk & & ./configure & & make & & ./objs/srs -c conf/srs.conf
```
Open [http://localhost:8080/ ](http://localhost:8080/ ) to check it, then publish
by [FFmpeg ](https://ffmpeg.org/download.html ) or [OBS ](https://obsproject.com/download ) as:
```bash
ffmpeg -re -i ./doc/source.flv -c copy -f flv -y rtmp://localhost/live/livestream
```
Play the following streams by [players ](https://ossrs.net ):
* RTMP (by [VLC ](https://www.videolan.org/ )): rtmp://localhost/live/livestream
* H5(HTTP-FLV): [http://localhost:8080/live/livestream.flv ](http://localhost:8080/players/srs_player.html?autostart=true&stream=livestream.flv&port=8080&schema=http )

Note that if convert RTMP to WebRTC, please use [`rtmp2rtc.conf` ](https://github.com/ossrs/srs/issues/2728#issuecomment-964686152 ):
* H5(WebRTC): [webrtc://localhost/live/livestream ](http://localhost:8080/players/rtc_player.html?autostart=true )

HLS: Fix on_hls and hls_dispose critical zone issue. v5.0.174 (#3781)
on_hls and hls_dispose are two coroutines, with potential race
conditions. That is, during on_hls, if the API Server being accessed is
slower, it will switch to the hls_dispose coroutine to start cleaning
up. However, when the API Server is processing the slice, a situation
may occur where the slice does not exist, resulting in the following
log:
```

Similarly, when stopping the stream, on_hls will also be called to
handle the last slice. If the API Server is slower at this time, it will
enter hls_dispose and call unpublish repeatedly. Since the previous
unpublish is still blocked in on_hls, the following interference log
will appear:
```
[2023-08-22 12:03:18.748][INFO][40][6498088c] hls cycle to dispose hls /live/stream-44572-2739617660809856576, timeout=10000000ms

[2023-08-22 12:03:18.752][WARN][40][6498088c][115] ignore the segment close, for segment is not open.
```
Although this log will not cause problems, it can interfere with
judgment.
The solution is to add an 'unpublishing' status. If it is in the
'unpublishing' status, then do not clean up the slices.
