mpeg2: fix decoding of multiple slices with same slice_vertical_position.
...
6.3.15 says that "some slices may have the same slice_vertical_position,
since slices may start and finish anywhere". So, we can't submit the current
picture to the HW right away since subsequent slices would be missing.

decoder: properly reference count pictures.

next picture.

decoder: rework the internal VA objects API.
...
The new API simplifies a lot reference counting and makes it more
flexible for future additions/changes. The GstVaapiCodecInfo is
also gone. Rather, new helper macros are provided to allocate
picture, slice and quantization matrix parameter buffers.
