This patch was designed to be generic and thus usable for all kinds of sockets. Not sure, thah this goal has been reached, but at least I tried. Key ideas: 1) sockets queue dump file have to be readed first and then packets entries with offset for it's data in image will be collected in doubly linked list by read_sockets_queue() function. Note: list will contain sockets queues for all (!) the sockets of the task. 2) socket queue can be restored by restore_socket_queue(), which selects packets from the list by passed id and use sendfile() top send them to the passed socket. It also removes packet from the list and frees it. Based on xemul@ patches.
