Fix toward ONOS-960 - Signed/unsigned value mismatch for OpenFlow-related
match/action conditions

Fixed the signed/unsigned issue for the match conditions

Also:
  * Reordered some of the code in CriterionCodec.java so the order
    of handling various Criterion types follows the order as defined in
    Criterion.java
    - In the process, removed a duplicated entry for Type.MPLS_LABE
    - Fixed an issue with TCP/UDP/SCTP ports being accessed as 8-bit integers
      instead of 16-bit integers

  * Updated some of the unit tests in CriterionCodecTest.java to use
    larger integer values that could expose better potential bugs in
    the tested code.
