igb: add new data structure for handling interrupts and NAPI

Browse Source 
Add a new igb_q_vector data structure to handle interrupts and NAPI.  This
helps to abstract the rings away from the adapter struct.  In addition it
allows for a bit of consolidation since a tx and rx ring can share a
q_vector.
