player: separate controls for user and video controlled speed

For video sync, we want separate playback speed controls for user-
requested speed and the "correction" speed for video timing. Further, we
use this separation to make sure only a resampler is inserted if
playback speed is only changed for video sync correction.

As of this commit, this is basically inactive code. It's just
preparation for the video sync code (the following commit).
