netdev-vport: Build on all platforms.
This patch removes the final bit of linux specific code which
prevents building netdev-vport everywhere. With this, other
platforms automatically get access to patch ports, and (if their
datapath supports it), flow based tunneling.

lib: Switch to flow based tunneling.
With this patch, ovs-vswitchd uses flow based tunneling
exclusively. I.E. each kind of tunnel shares a single tunnel
backer in the datapath. Tunnel headers are set by userspace using
the ipv4_tunnel datapath action. And, the configuration of
individual tunnels is now a userspace responsibility, so
netdev-vport no longer marshals and unmarshals Netlink attributes
for tunnel configuration, instead only storing the configuration
internally. There are still some significant pieces of work to do,
but the basic building blocks are there to begin testing.

tunnel: Userspace implementation of tunnel manipulation.
The kernel tunneling code currently needs to handle a large number
of operations when tunnel packets are encapsulated and
decapsulated. Some examples of this are: finding the correct
tunnel port on receive, TTL and ToS inheritance, ECN handling, etc.
All of these can be done on a per-flow basis in userspace now that
we have both the inner and outer header information, which allows
us to both simplify the kernel and take advantage of userspace's
information. Once tunnel packets are redirected into this code,
the redundant pieces can be removed from other places.

netdev: New function netdev_get_dpif_port().
In future patches, a netdev's datapath port name may not
necessarily be the same as its device name. This patch prepares for
this by making the distinction in the netdev and dpif layers.

ofproto-dpif: Install drops for flows from invalid in_ports.
Before this patch, if a packet came in on a port which userspace
doesn't know about, it would be silently dropped without installing
a drop flow. Historically, this has been fine because this
situation could only occur during transient reconfiguration
periods. However, in future, this could occur when the tunneling
code decides to reject a packet due to invalid headers. In this
case, it's preferable to drop the packet in the kernel to avoid a
high bandwidth stream of invalid packets DoSing the switch.

ofproto-dpif: Require an in_port when tracing datapath flows.
All datapath flows should have an in_port, so it doesn't make a lot
of sense to allow omitting it when tracing. If a user wants to
trace a flow which has no in_port, they can use the OpenFlow syntax
which doesn't go through ofproto_receive().
