This avoids calls to get_unsigned_bits() with constants and
replaces hard to trace loops with simpler structures.

For bad input data, the decoder may access the array out of bounds. The
commit added clamp to prevent such out of bound access

Values of MODE_UPDATE_PROB and VP9_COEF_UPDATE_PROB are equal, so replacing
them with one constant. Inlining appropriate arguments for functions:
vp9_cond_prob_diff_update (encoder)
vp9_diff_update_prob (decoder)

Uses mapping tables instead of complicated modulo/division
operations for prob mapping for forward updates.
No bit-stream or output change.
