datapath-windows: Fixes in OvsSetVportCmdHandler()

In this patch, we make a few simple fixes based on reviewing the code.
The code as such is not tested. We'll be hitting the code path soon
and might make more fixes at that time.

ofproto-dpif-xlate: Use bfd forwarding status in fast-failover groups.

Integration of each interface' status as confirmed by BFD into the
FastFailover Group table. When BFD is configured and function
bfd_forwarding() reports false, odp_port_is_alive also reports false in
order to have a watched interface report false and omit to another
backup.

Test-suite has been succesfully run, as well as testing with ICMP echo
requests and replies that traffic was succesfully rerouted over the
backup path. More extensive load-consumption tests with a function that
only checked whether (bfd->state == STATE_UP) have been succesfully
performed, but was later changed to use the larger function
bfd_forwarding() as it captures all possible exceptions and is properly
mutually excluded.

docker: Integrate docker containers with Open vSwitch.

Open vSwitch does not have native integration with Docker.
INSTALL.Docker explains how Open vSwitch can be integrated
with docker non-natively.

ovs-docker is a helper script to add network interfaces to
docker containers and to attach them as ports to OVS bridge.
This script can be further enhanced as we understand different
use cases.

lib/dpif-netdev: Integrate megaflow classifier.

Megaflow inserts and removals are simplified:

- No need for classifier internal mutex, as dpif-netdev already has a
  'flow_mutex'.
- Number of memory allocations/frees can be halved.
- Lookup code path can rely on netdev_flow_key always having inline data.

This will also be easier to simplify further when moving to per-thread
megaflow classifiers in the future.

lib/dpif-netdev: Fix EMC lookup.

Patch 0de8783a9 (lib/dpif-netdev: Integrate megaflow classifier.)
broke exact match cache lookup, but it went undetected since there are
no separate stats for EMC.

This patch fixes the problem by changing the struct netdev_flow_key
'len' member to cover only the 'mf' member, not the whole
netdev_flow_key, and ignoring the 'len' field in
netdev_flow_key_equal.  Comparison is still accurate, as the miniflow
'map' field encodes the length in the number of 1-bits, and the map is
included in the comparison.

userspace: add support for pop_eth and push_eth actions

These actions will allow L2->L3 and L3->L2 switching, and are supposed

userspace: add layer 3 flow and switching support

This commit relaxes the assumption that all packets have an Ethernet
header, and adds support for layer 3 flows.  For each packet received on
the Linux kernel datapath the l2 and l3 members of struct ofpbuf are
intialized appropriately, and some functions now expect this (notably
flow_extract()), in order to differentiate between layer 2 and layer 3
packets.  struct flow has now a new 'base_layer' member, because we
cannot assume that a flow has no Ethernet header when eth_src and
eth_dst are 0.  For layer 3 packets, the protocol type is still stored
in the eth_type member.

Switching L2->L3 and L3->L2 are both implemented by adding the pop_eth
and push_eth actions respectively when a transition is detected.  The
push_eth action puts 0s on both source and destination MACs.  These
addresses can be modified with mod_dl_dst and mod_dl_src actions.

Added new prerequisite MFP_ETHERNET for fields MFF_ETH_SRC, MFF_ETH_DST,
MFF_VLAN_TCI, MFF_DL_VLAN, MFF_VLAN_VID and MFF_DL_VLAN_PCP.
