This patch adds a new compatibility enum for use with MPLS, so that the
differing behaviour between OpenFlow 1.2 and 1.3 can be implemented in
ofproto-dpif-xlate.

It seems a little awkward to me to do this via a new OFPACT_, mostly
because there isn't currently any distinction between OF1.1 and OF1.3 in
terms of OFPACT_ definitions.  Did you consider adding a new field to
struct ofpact_push_mpls that would say whether the label should be added
before or after a VLAN tag?
