ANDROID: netfilter: adding the original quota2 from xtables-addons

Browse source 
The original xt_quota in the kernel is plain broken:
  - counts quota at a per CPU level
    (was written back when ubiquitous SMP was just a dream)
  - provides no way to count across IPV4/IPV6.

This patch is the original unaltered code from:
  http://sourceforge.net/projects/xtables-addons

  at commit e84391ce665cef046967f796dd91026851d6bbf3
