core: add Manager parameter to fifo_control_loop() so it can be used from main directly
main-no-init: parameter
control-request: access check on fifoctl to avoid false error messages
analyze: reduce to a stub for now

systemd-analyze's operation is heavily dependent on querying various
unit and manager properties like timestamps from the bus. We will have
to rewrite its logic to do it in a rawer fashion, but for now let's
print out a message.
core: go back to a void control loop
socket: remove unused SMACK* options
control-request: add scaffolding for set-property
control-response-util: expand signature of cgroup_set_property() to include a switchable param
control: fix some omissions
control-response-util: set up file parsing and initialize CPUAccounting boolean option
control-response-util: set up BlockIOAccounting
control-response-util: set up MemoryAccounting
control-response-util: set up MemoryLimit
control-response-util: param, not name
control-response-util: add stub for unit_systemctl_status_print()
control-response-util: set up DevicePolicy
control-response-util: proper format for unit active state in unit_systemctl_status_print()
