Sebastian Dröge 405b47a79a playsink: Fix gapless playback in many non-simple scenarios
Before gapless playback failed when switching between audio-only,
video-only and audio-video files, when choosing different clocks
and when the different streams had different durations.

This is now handled by a helper element, which keeps track of the
running times of all streams and synchronizes them.

Fixes bug #602437.
