This is possible now that the next-API is gone.

If avio_read() returns a value of bytes read that's lower than the
expected, return an error instead. And when there are zero bytes in
the prefetch buffer, return 0 in order for the frame merge bsf to
drain all potentially buffered packets.
Missed by mistake when amending and committing 9a7bdb6d71.

The current approach has two different calls to av_bsf_send_packet():
A normal one, sending a packet; and an extraordinary one just for
flushing. These can be unified into one by making use of the newly
documented fact that av_bsf_send_packet() allows to signal flushing via
empty packets (i.e. packets without data and side-data).
This also fixes CID 1455685 which resulted from the fact that the call
for flushing was not checked given that it couldn't fail.
