datapath-windows: Alg support for ftp and tftp in conntrack

This patch mainly support alg field in ct action when process
ftp/tftp traffic. Tftp with alg mainly parse the tftp packet
 (IPv4/IPv6), extract connect info from the tftp packet and
 create the related connection. For ftp, previous version has
 supported process of ftp traffic. However, previous version
 regard traffic from or to port 21 as ftp traffic, this is
 incorrect in some scenario. This version adds alg field in ct for
 ftp traffic, we could use ct(alg=ftp) to process any ftp traffic
 from/to any port.

IPv4/IPv6.

Test cases:
    1) ftp ipv4/ipv6 use alg field in the normal and nat scenario.
    2) tftp ipv4/ipv6 use alg field in the normal and nat scenario.
