ofproto-dpif: Implement patch ports in userspace.
		
This commit moves responsibility for implementing patch ports from
the datapath to ofproto-dpif.  There are two main reasons to do
this.

The first is a matter of design:  ofproto-dpif both has more
information than the datapath, and is better suited to handle the
complexity required to implement patch ports.

The second is performance.  My setup is a virtual machine with two
basic learning bridges connected by patch ports.  I used
ovs-benchmark to ping the virtual router IP residing outside the
VM.  Over a 60 second run, "ovs-benchmark rate" improves from
14618.1 to 19311.9 transactions per second, or a 32% improvement.
Similarly, "ovs-benchmark latency" improves from 6ms to 4ms.

ofproto-dpif: Refresh stats before ovs-appctl dpif/dump-flows.
		
As a matter of convenience, this patch refreshes the statistics
when ovs-appctl dpif/dump-flows is called.  Hopefully this will
prevent users from being confused because statistics they were
expecting to see haven't made it from the datapath into the switch
yet.

commit 2cc3c58ee8db0dba3f01ba39f573b6e62b883247

ofproto-dpif: Scope revalidation state to dpif_backers.
		
Before this patch, the "need_revalidate" flag and the
"revalidate_set" tag_set where maintained separately for each
ofproto.  This won't work in future patches when a flow table
change in one ofproto can require revalidation in another entirely
separate ofproto.  For this reason, this patch scopes these flags
to the dpif_backers.
