Support include empty config file. v5.0.173 v6.0.68 (#3768)
Browse files Browse the repository at this point in the history
## Include Empty Config File

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.
