Bugfix: Criteria.toString() does not convert unsigned variables properly.

For example, in the response of 'flows' command, the ethType of IPv6 (0x86dd) is shown as ff..ff86dd instead of 86dd
Note: VlanId/VlanPcp still remains in signed format in this commit since:
  * VLAN tag is actually 12 bits. There should be no problem even if it is printed as signed short.
  * VLAN PCP is actually 3 bits. There should be no problem even if it is printed as signed short.
  * -1 is used in many places to indicate untagged vlan
