This adds a way for an API user to transfer QP data and metadata without having to keep the reference to AVFrame, and without having to explicitly care about QP APIs. It might also provide a way to finally remove the deprecated QP related fields. In the end, the QP table should be handled in a very similar way to e.g. AV_FRAME_DATA_MOTION_VECTORS. There are two side data types, because I didn't care about having to repack the QP data so the table and the metadata are in a single AVBufferRef. Otherwise it would have either required a copy on decoding (extra slowdown for something as obscure as the QP data), or would have required making intrusive changes to the codecs which support export of this data. The new side data types are added under deprecation guards, because I don't intend to change the status of the QP export as being deprecated (as it was before this patch too).
