66d5e43b99 avformat/utils: Fix memleaks 
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.

e045be92cd avformat/utils: Assert that stream_index is valid 
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.

f83ac5fd79 avcodec/cbs_h264: Automatically free SEI payload on error 
If adding an SEI message to an access unit fails, said SEI message was
not touched, so that the caller had to free any data associated with it
that might need to be freed. But given that ff_cbs_h264_add_sei_message
can simply call cbs_h264_free_sei_payload, one can easily free
the content of the SEI payload.

This fixes a memleak when inserting a user data unregistered string for
h264_metadata fails.
