The macro block mode info context originally contained an entry for each 16x16 macroblock. In VP9 each entry refers to an 8x8 region not a macro block, so the naming is misleading. This first stage clean up changes the names of 3 entries in the structure to remove the mb_ prefix. TODO clean up the nomenclature more widely in respect of mbmi and bmi.
