basesink: clip stepping boundaries

Browse source 
Rounding errors with the floating point rate could make it so that we
don't end up exactly at the required stepping duration.
Use the segment clipping boundaries, which are not subject to rate
adjustements, instead to detect when we reached the stepping duration.

Add some debug info related to going to the PAUSED state.
