Fixes ticket #3181.

Fixes ticket #3184

It was previously int and would return error if decode_coeffs_b()
returns an error; however, that can never happen, so refactor all
that code to make all dependent functions return void also (all the
way up to decode_coeffs_sb()).

The old one didn't use segmentation. One uses segmentation in all frame
types (--aq-mode=1), and the other uses all segmentation features, but
only in inter frames (mbgraph).

This disables backward probability updates, which makes the codec more
friendly for frame-level multi-threading.
