I'm pretty happy with this.

The one bit that I'm concerned about is that it allows OpenFlow 1.4 to
be enabled even though there are unimplemented messages that will cause
Open vSwitch to abort if ovs-vswitchd receives one (or tries to send
one).  We need to avoid that somehow; one way would be to not allow
OpenFlow 1.4 to be enabled as long as any of those messages exist.
