Refactoring of encode loop and bitstream packing Some code re-factored / moved to allow the main pack operation inside the recode loop so that the size estimate is accurate. Deletion of some redundant code relating to one pass. Aproximate improvement over March 27 code base: Derf 0.0%, YT 0.5%, YThd 0.3% Std_hd 0.25% Change-Id: Id2d071794ab44f0b52935f6fcdb5733d09a6bb86
