Conntrack module is part of OVS datapath on Windows and lacks netlink support.
The following patches adds support in Windows datapath for accepting
netfilter-netlink messages from userspace and executing the command. The
supported commands include flushing conntrack entries and dumping them.
Netfilter's conntrack related header files have been added to Windows to limit
the userspace changes. Some of them have been intentionally left empty since
Windows datapath does not support them.
