dpif-netdev: Avoid variable length array on MSVC.

MSVC does not like variable length array either.

This patch treats the following error:

ofp-actions: Support "resubmit" actions in action sets.

Fixing issue where "resubmit" action in a group action set was not
considered sufficient to retain the full action set. This patch allows
a group action set (considered terminal with OF1.4 and earlier spec)
to have the "output" action come from a different table.

getopt_long: Fix broken sequence of casts in __UNCONST macor.

Unlike the compilation mode used for OVS x64 Linux Windows long word is

Replaced _UNCONST macro with CONST_CAST to avoid the intermediate casting
to an integer.

Testing: 32 and 64 Windows builds.

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.
