This cleans up the handling of modifying existing flows. There now exists OFPFC_MODIFY and OFPFC_MODIFY_STRICT commands, which have the same matching characteristics to their OFPFC_DELETE* counterparts. When adding a flow that already exists, the counters and timers are now reset (ie, its treated as a new flow). This commit also adds the "--strict" option to dpctl to allow strict matching for "mod-flows" and "del-flows".
