Subject: syslog-ng - code style fixes

- Update copyright header
- Code style fixes
- Fix indentation
- Use get_interface_ip() instead of parsing ifconfig output
- Use {start,stop,restart}_service() instead of exec()
- Use rename() instead of mv.
- Use platform_booting() to check whether system is booting
