ofproto: Match VLAN PCP and rewrite ToS bits (OpenFlow 0.9)

Browse Source 
Starting in OpenFlow 0.9, it is possible to match on the VLAN PCP
(priority) field and rewrite the IP ToS/DSCP bits.  This check-in
provides that support and bumps the wire protocol number to 0x98.

NOTE: The wire changes come together over the set of OpenFlow 0.9 commits,
so OVS will not be OpenFlow-compatible with any official release between
this commit and the one that completes the set.
