datapath: Add support for kernels 3.13
Add support for building the in-tree kernel datapath for
Linux kernels up to 3.13. There were some changes in the
netlink area which required adding new compatibility code
for this layer. Also, some new per-cpu stats initialization
code was added.
Based on patch from Kyle Mestery.
