install: add new installer implementation This new installer will replace the current code of "systemctl enable" but also be available via D-Bus. It adds a couple of new features: - Mask/Unmask calls - Reenable call - Preset call - Support for enabling units temporarily (i.e. in /run/systemd instead of /etc/systemd) - Enumeration of installed units - Support for out-of-search-path units systemctl and D-Bus are not hooked up with this yet
