IPVS stats are limited to 2^(32-10) conns/s and packets/s,
2^(32-5) bytes/s. It is time to use 64 bits:
* Change all conn/packet kernel counters to 64-bit and update
them in u64_stats_update_{begin,end} section
* In kernel use struct ip_vs_kstats instead of the user-space
struct ip_vs_stats_user and use new func ip_vs_export_stats_user
to export it to sockopt users to preserve compatibility with
32-bit values
* Rename cpu counters "ustats" to "cnt"
* To netlink users provide additionally 64-bit stats:
IPVS_SVC_ATTR_STATS64 and IPVS_DEST_ATTR_STATS64. Old stats
remain for old binaries.
* We can use ip_vs_copy_stats in ip_vs_stats_percpu_show
Thanks to Chris Caputo for providing initial patch for ip_vs_est.c
