Current method for constraining fragment position drift suffers from
round-off error build up.

Instead of calculating cumulative drift as a sum of input fragment
position corrections, it is more accurate to calculate drift as the
difference between current fragment position and the ideal position
specified by the tempo scale factor.

The value of coeff_per_sb_select depends on the bit rate, not on
sub_sampling.
Also remove the calculation of tmp, no longer needed.
