eb17bf6fd3 mpeg4_unpack_bframes: Avoid allocations and copies of packet structures 
1. Since bd90a2ec, mpeg4_unpack_bframes caches whole packets instead of
just the pointer to the buffer and the buffer's size in order to be able
to make use of refcounting to avoid copying of data; this unfortunately
introduced copies of packet structures and side data (if existing),
although the only fields that are needed are the buffer-related ones
(data, size and buf). This can be changed without compromising the
advantages of refcounting by storing a reference to the buffer.

2. This change also makes it easy to use only one packet throughout
so that an allocation and free of an AVPacket structure per filtered
packet can be saved by switching to ff_bsf_get_packet_ref.

3. Furthermore, this commit also fixes a memleak introduced in bd90a2ec:
If a stored b_frame with side data was used for a later frame, the side
data would leak when the input frame's properties were copied into the
output frame.

b288a7eb3d avformat/mpegenc: Fix memleaks and return values 
If there is an error in mpeg_mux_init() (the write_header function of
the various MPEG-PS muxers), two things might happen:

1. Several fifos might leak. Instead of freeing them, the goto fail part
of the functions freed the private data of the AVStreams instead,
although this will be freed later in free_stream() anyway.
2. And if the function is exited via goto fail, it automatically
returned AVERROR(ENOMEM), although this is also used when the error is
not a memory allocation failure.

Both of these issues happened in ticket #8284 and have been fixed.

ba191c0ce0 vp9_superframe: Avoid allocations and copies of packet structures 
Up until now, the vp9_superframe bsf used distinct packets for input and
output. But at no point in the bsf are the input and output packets used
at the same time (except during a call to av_packet_move_ref()), so that
one can avoid using two packets if one switches to ff_bsf_get_packet_ref
at the same time. This also saves one malloc+free of an AVPacket
structure per filtered packet.

6aae322120 avfilter/af_arnndn: Remove superfluous qualifier 
remove_doubling() returned a const float, but returning qualified types
is pointless anyway. This is all the more important given that  GCC 4.2.1
(and maybe other compilers, too) seems to treat this as an error as several
FATE units that don't compile any more show.
