openflow-1.1+: OFPT_TABLE_MOD (part 1)

Browse Source 
Added infrastructure to support Openflow OFPT_TABLE_MOD message. This patch
does not include the flexible table miss handling code that is necessary to
support the semantics specified in OFPT_TABLE_MOD messages.

Current flow miss behavior continues to conform to Openflow 1.0.  Future
commits to add more flexible table miss support are needed to fully support
OPFT_TABLE_MOD for Openflow-1.1+.
