FreeBSD insists that <sys/types.h> be included before <netinet/in.h> and
that <netinet/in.h> be included before <arpa/inet.h>. This adds guards to
the "sparse" headers to yield a warning if this order is violated. This
commit also adjusts the order of many #includes to suit this requirement.

OVS router is basically partial copy of linux kernel FIB.
kernel routing table uses skb-mark along with usual routing
parameters. Following patch brings in support for skb-mark
to ovs-router so that we can lookup route for given skb-mark.

Device can have multiple IP address but netdev_get_in4/6()
returns only one configured IPv6 address. Following
patch fixes it.
OVS router is also updated to return source ip address for
given destination, This is required when interface has multiple
IP address configured.

This adds support for IPv6 in ovs-router and route-table. IPv4 is stored in
ovs-router using IPv4-mapped addresses.

Refactor ovs-router so that it can work with non-Linux platforms
at least in some extent, using the existing route-table code as
a fallback. Known restriction: for such platforms, "ovs/router/show"
command does not show "Cached" kernel routes.

Split the linux-specific part of ovs-router.h
into ovs-router-linux.h.
The breakage was introduced by

("route-table: Use classifier to store routing table.")

Rather than using hmap for storing routing entries we can directly use
classifier which has support for priority and wildcard entries.
This makes route lookup lockless. This help when we use route lookup
for native tunneling.
