datapath-windows: Add Connection Tracking Support
Enable support for Stateful Firewall in Hyper-V by adding a Connection
Tracking module. The module has been ported over from the userspace
implementation patch of a similar name.
The current version of the module supports ct - zone, mark and label for
TCP packets. Support for other packet formats will be added in subsequent
patches.
The conntrack-tcp module is adapted from FreeBSD's pf subsystem and hence
the BSD license. It has been ported over to match OVS Hyper-V coding
style.
