From: Jan Ekström <jee...@gmail.com>
Use AV1DecContext's current_obu to access the original OBUs, and
feed them to videotoolbox, rather than the bare slice data passed
via decode_slice.
This requires a small addition to AV1DecContext, for keeping track
of the current range of OBUs that belong to the current frame.

v2: Use current_obu for accessing the original OBUs, rather than
trying to reassemble things from the parts passed via the
start_frame/decode_slice callbacks.
If a packet consists of one frame, we can pass the whole frame
as is, but if it consists of multiple frames, we need to pass
a limited range of OBUs corresponding to each frame at a time.
By passing all OBUs, we end up passing all OBUs to videotoolbox,
including metadata ones that we otherwise handle ourselves.
