MSDK does not create internal acceleration device on Linux,
So MFXVideoCORE_SetHandle() is necessary.
It has been added for ff_qsv_init_session_device().
But missed for ff_qsv_init_internal_session() due to commit

This is done so that its data is really owned by the packet.
This was already true for the current callers.

Up until now, ff_packet_list_put had a flaw: When it moved a packet to
the list (meaning, when it ought to move the reference to the packet
list instead of creating a new one via av_packet_ref), it did not reset
the original packet, confusing the ownership of the data in the packet.
This has been done because some callers of this function were not
compatible with resetting the packet.

This commit changes these callers and fixes this flaw. In order to
indicate that the ownership of the packet has moved to the packet list,
pointers to constant AVPackets are used whenever the target of the
pointer might already be owned by the packet list.

Demuxers may have allocated a packet before encountering an error and aborting.

ff_read_packet had potential memleaks:
1. If av_packet_make_refcounted fails, it means that the packet is not
refcounted, but it could nevertheless carry side data and therefore
needs to be unreferenced.
2. If putting a packet on a packet list fails, it wasn't unreferenced.

Furthermore, read_frame_internal leaked a packet's (side) data if a
context update was required and failed.

There is currently an ordinary check for this (which would lead to a
memleak), but given that no demuxer should ever return a packet with an
invalid stream_index it is more appropriate for this to be an assert.

FATE passes with this change.
