MediaSample::applyPtsOffset() had a rather confusing name, so it has been changed to something more descriptive of its actual function: extendToTheBeginning(). Also, its only argument has been removed, as it's always zero. An explanation of the hack has also been added. This patch introduces no behavior changes.
