IPVS: Backup, Adding Version 1 receive capability

Browse Source 
Functionality improvements
 * flags  changed from 16 to 32 bits
 * fwmark added (32 bits)
 * timeout in sec. added (32 bits)
 * pe data added (Variable length)
 * IPv6 capabilities (3x16 bytes for addr.)
 * Version and type in every conn msg.

ip_vs_process_message() now handles Version 1 messages
and will call ip_vs_process_message_v0() for version 0 messages.

ip_vs_proc_conn() is common for both version, and handles the update of
connection hash.

ip_vs_conn_fill_param_sync()    - Version 1 messages only
ip_vs_conn_fill_param_sync_v0() - Version 0 messages only
