began stubbing out various sdn modules
added port stuff and changed some naming
Fleshed out more of the port structures, queue structures, table structures...
Began work on translating the OpenFlow Feature_reply into 'sdn' (tinyNBI) structures
Restructured some structs and functions and added a function to set the features of a port based on a ofp v1.0 feature reply's port's features.
Moved functions that relied on ofp from sdn/* to nocontrol/*. Also finished more of the port section of the datapath configuration function.
Restructured the tables to be associative, did more work with the feature reply, and added comments to prepare this project for an inactive period.
Merge branch 'akron/sdn'
