videodecoder, videoencoder: support "partial" frames / slices for raw video

Submitted by Sebastian Dröge Link to original bug (#660770)
Description
Currently basevideodecoder and basevideoencoder handles everything in units of complete frames. This is suboptimal in some cases, when you could pass "partial" frames to the decoder already to reduce decoding latency, e.g. h264 NALs.
