This way a caller doesn't need to implement the logic for which (and how many) tokens to write out to stuff one macroblock worth of EOBs. Make the actual function implementations static, since they are now only used in tokenize.c; also do some minor stylistic changes so it follows the style guide a little more closely; use PLANE_TYPE where appropriate, remove old (stale) frame_type function arguments; hardcode plane type where only a single one is possible (2nd order DC or U/V EOB stuffing); support stuffing 8x8/4x4 transform EOBs with no 2nd order DC.
