ofproto-dpif: Fix nondeterministic flow revalidation behavior.

SLB bonds are very strange beasts.  It's taken OVS a while to figure out
how they should really work.  Way back in the mists of time, when we were
in the midst of this process, we noticed that the following could happen:

1. Local VM sends a packet to the OVS bridge.
2. OVS bridge learns VM's MAC, forwards packets to SLB bond.
3. Remote switch hasn't learned packet's destination and
   forwards packet back to other interfaces in the SLB bond.

Normally nothing bad happens in this scenario because OVS has already
learned the local port for the VM's MAC in step 2 and the rules for SLB
bonding (this is rule #2 in vswitchd/INTERNALS).  But at the time we were
implementing this, OVS didn't yet use active flows to keep MAC learning
entries alive; only new flows prevented a MAC entry from aging out.  So
in steady state (e.g. just "ping" traffic) OVS would regularly forget MAC
addresses.  If the remote switch also happened to forward a packet back to
one of the SLB bond interfaces, then OVS would learn the VM's address on
the bond, with the result that any traffic coming in from the remote switch
would be black-holed until the VM sent a new packet.  This was not good.

The fix we applied at the time was commit 2416b8ecea (bridge: Eject NORMAL
flows without a learning entry from datapath.) followed by a small
refinement in commit e96a4d8035 (bridge: Feed flow stats into learning
table.).  This fix causes flows that don't have a learning entry to be
ejected from the datapath if revalidation occurs.  This forced the next
packet in the flow to go to userspace, which in turn caused learning to
happen, fixing the problem.

However, this isn't a good solution for several reasons:

* It forces more packets to userspace, which is expensive.

* It doesn't just affect the cases where it helps, those where an
  SLB bond is actually involved.  (This could be fixed, but it is
  not worth it.)

* It means that flow installability becomes nondeterministic.  When
  the first packet shows up for a flow, we install it.  But later
  if we revalidate it, we have to uninstall it.  That doesn't make
  sense; a flow should be either installable or not installable,
  not some weird mix.

Fortunately, the situation has improved since this fix was originally
designed.  First, active flows now keep MAC learning entries alive, since
commit e96a4d8035367 (bridge: Feed flow stats into learning table.)
Second, gratuitous ARP locking, added in commit 7febb9100b (bridge: Filter
some gratuitous ARPs on bond slaves.) means that gratuitous ARPs reflected
on bond slaves don't cause confusion (this is rule #4 in
vswitchd/INTERNALS).

These improvements mean that it is no longer necessary to have this
strange special case at all.  Therefore, this commit removes it.

I found this while investigating reports from code that I added to
occasionally check that flow actions were correct.

ofproto-dpif: Flush MACs for deleted ports from every bridge.

Consider this scenario: two hypervisors HV-1 and HV-2, connected to a
common physical network over SLB bonds.  Two virtual machines VM-1 and VM-2
are both running on HV-1.  Patch ports are in use, so that each VM is not
connected to a bridge with a physical Ethernet port but is actually one
virtual "hop" away across a patch port to a second OVS bridge.  VM-2 is
running a "ping" process directed at VM-1.

Now migrate VM-1 to HV-2.  Suppose that VM-1 fails to send out a gratuitous
ARP following migration, or that the gratuitous ARPs are lost, e.g. because
they are sent before the OpenFlow controller manages to populate the flow
table with rules to allow the VM's traffic

Now we are in a situation where HV-1 has learned that VM-1 is local and
HV-2 has learned that VM-1 is on its bond; both are wrong.  One would
expect the problem to resolve itself as soon the VM-1 sends out its first
packet.  However, SLB bonds (for important reasons documented in
vswitchd/INTERNALS) are very reluctant to learn that a currently local MAC
is actually on the bond: the only ways to learn that the MAC is on the bond
are to receive a gratuitous ARP (which we won't, since they were dropped)
or for the MAC learning entry to expire after 60 seconds. This means that
VM-1 can send out as much ordinary traffic as it wants (even ARP requests
and other broadcasts) but HV-1 will drop all of it at the physical Ethernet
since it believes that VM-1 is local.

(In an ordinary setup with a single bridge, HV-1 would have unlearned the
address for VM-1 when VM-1's port was deleted, but that didn't happen
because HV-1 only learned that VM-1 was on the patch port that leads to the
integration bridge.  The patch port didn't get deleted.)

HV-2 does quickly learn that VM-1 is now local.  SLB bonds are only
reluctant to learn that something they think is local is actually on the
bond, not the reverse.

This commit attempts to work around the problem by flushing the MAC
associated with a port from *every* bridge when a port is deleted.

This commit demonstrates yet another good reason not to use SLB bonds.

Build and unit tested only.

When dpif-netdev is in use as a "dummy" datapath, the devices that are
added to it have type "dummy", but the dpif methods that report the types
of ports reported that they had type "system".  This meant that every time
the bridge code reconfigured, it would see that the ports had the wrong
