Shu Shen 2889711e46 ofproto: Openflow 1.5 support (work-in-progress) 
Work done:
- The baseline is copied over from ofproto_v1_4.py and
  ofproto_v1_4_parser.py and into ofproto_v1_5.py and
  ofproto_v1_5_parser.py respectively.
- Most of structs, enums, and pack strings in ofproto_v1_5.py has been
  updated to spec. Exception is oxs_fields has not been done yet.
- ofproto_v1_5_parser.py has not been updated except those necessary to
  allow run_tests.sh to complete successfully
- ofproto_protocol.py imports ofproto_v1_5 and ofproto_v1_5_parser now
- oxm_fields.py is updated for OFPXMC_PACKET_REGS
- Tests are updated to include Openflow v1.5 when it's obvious. But not
  much work has been done to acutally test v1.5 yet. I also found tests
  for v1.4 are scarce.

TODO:
- Add oxs_fields support. It shall be similar to oxm_fields
- Update and implement ofproto_v1_5_parser.py
- More tests, tests, tests.
