How to write and read the machine hostname is something that has been handled until now by plugins; this is questionable since the method using for storing the hostname should depend only on the distro used and not on which plugins are enabled. This commit moves all hostname-related functions from plugins to the core and allows to specify the method used to load and store the hostname at build time with the --with-hostname-persist=default|suse|gentoo configure option. 'default' method stores the hostname to /etc/hostname and monitors it to detect runtime changes. When the selected method is 'suse', the hostname gets read from and written to /etc/HOSTNAME; the file /etc/sysconfig/network/dhcp is also read to detect if the hostname is dynamic and thus invalid. Both files are monitored for changes. 'gentoo' method relies on /etc/conf.d/hostname for storing the hostname.
