- Install logrotate configuration file and protect it from replace
- Make bc-flexisip package depends upon 'logrotate'
- Really install SystemD units in /lib/systemd/system instead of having post-install scripts to make symbolic links to /opt/belledonne-communications/share/systemd/flexisip-*
- Deb: move the 'systemctl try-restart' command into 'postins' scrpit instead of 'postrm'.
