To unify packet types among all PMDs, bit masks of packet type for
'ol_flags' are replaced by unified packet type.
To avoid breaking ABI compatibility, all the changes would be
enabled by RTE_NEXT_ABI, which is disabled by default.

v2 changes:
* Used redefined packet types and enlarged packet_type field in mbuf.

v5 changes:
* Re-worded the commit logs.

v6 changes:
* Disabled the code changes for unified packet type by default, to
  avoid breaking ABI compatibility.

v7 changes:
* Renamed RTE_UNIFIED_PKT_TYPE to RTE_NEXT_ABI.
