netfilter -stable 00/08: netfilter -stable fixes

[Patrick McHardy <kaber@trash.net>]

Following are couple of netfilter fixes for -stable, fixing

- various races in nf_conntrack introduced by the conversion to use
  RCU for the conntrack hash and follow-up patch to use SLAB_DESTROY_BY_RCU
  for the conntrack slab

- direct userspace memory access in the nf_log /proc handler

- a missing initialization in the quota match, possibly causing malfunction
  on SMP

- an incorrect comparison in the rateest match

- unacknowledged data detection in TCP conntrack in combination with
  NAT helpers reducing the packet size

Please apply, thanks.
