Added common prediction modules. This function adds the common prediction modules, some data structures and a config option but does not use them. It also corrects a bug in clearing down the MODE_INFO border and introduces a new element that indicates if an entry corresponds to an "in image" macro block or is part of the border.

/*
Reference frame prediction: Extended prediction and coding of reference frame where a subset of options are flagged as available at the segment level. Updated copyright notices. Switch to SAD in mbgraph code as SATD problematic for the foreground and background separation as it can ignore large DC shifts. Change-Id: I661dbbb2f94f3ec0f96bb928c1655e5e415a7de1

Adding contextual coding of mb_skip_coeff flag. Using contextual coding of the mkb_skip_coeff flag using the values of this flag from the left and above. There is a small improvement of about 0.15% on Derf: http://www.corp.google.com/~debargha/vp8_results/mbskipcontext.html Refactored to use pred_common.c by adding a new context type. Results on HD set (about 0.66% improvement): http://www.corp.google.com/~debargha/vp8_results/mbskipcontext_hd.html Incliding missing refactoring to use the pred_common utilities.
