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).

Everything related to the QP data is deprecated, with qp_table_buf being
an inconsistent exception. Some parts were under the deprecation guards,
some not. It probably didn't even compile.

There's no need to allocate a new packet for it.
Signed-off-by: James Almer <jamrial@gmail.com>

In cases where the mediacodec decoder consumed a partial packet,
receive_frame() would start returning EAGAIN if the rest of the
packet couldn't be flushed and no frames were immediately available.

This fixes receive_frame() to perform its normal blocking wait for
new frames before returning EAGAIN. Fixes an issue I could reproduce
fairly often on a FireOS 6 device, and reported to be happening
intermittently by two mpv users.
