Same funcionality is provided by stereo3d=ab[2]{l,r}:sbs[2]{l,r}.
Additional "features" are barely useful and cause crash or artifacts.

Before, this code was labeled as mmxext and enabled both for the
3dnow and the mmxext case.

The current code can fail to return the last frame if it contains
exactly the requested number of samples.

Fixes the join filter test, which previously did not include the last
408 samples in most cases.

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.
