This af_unix socket is used for:
(1) sending command to lxc-start (the supervisor of the container's init)
- 'stop': used by lxc-stop to kill the container, the lxc-stop exits
when the af_unix connection is closed, so we have the guarantee the
'stop' will return after the container dies, so we can call lxc-start
right after lxc-stop.
- 'pid' : get the real pid of the init process
- 'state' : get the state of the container which is monitored by
lxc-start
(2) get a tty file descriptor using the fd passing af_unix mechanism, so
lxc-console can work.
