Pavel Koshevoy 0c77cdb491 libavfilter/af_atempo: Avoid round-off error build-up, ticket #2484 
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.
