systemctl,loginctl,cgls: do not ellipsize cgroup members when --full is specified
New file output.h with output flags and modes. --full parameter also for cgls and loginctl. Include 'all' parameter in flags (show_cgroup_by_path, show_cgroup, show_cgroup_and_extra, show_cgroup_and_extra_by_spec). get_process_cmdline with max_length == 0 will not ellipsize output. Replace LINE_MAX with 0 in some calls of get_process_cmdline. [zj: Default to --full when under pager for clgs. Drop '-f' since it wasn't documented and didn't actually work. Reindent a bit. ]
