New restore option 'tcp-close' was introduced. It restores all connected
TCP sockets in TCP_CLOSE state. Here we consider tcp sockets in
TCP_ESTABLISHED, TCP_FIN_WAIT2, TCP_FIN_WAIT1, TCP_CLOSE_WAIT,
TCP_LAST_ACK, TCP_CLOSING, TCP_SYN_SENT states as connected sockets.
This is consistent with current CRIU usage of these states. Thus this
option doesn't affect sockets with original states of TCP_LISTEN and
TCP_CLOSE.
