Many H.264 derivatives, like RV40 and VP8, use the H.264 prediction functions
but not the weight/loopfilter functions.
This should reduce the size of builds with one of these derivatives but without
H.264 decoding itself.

AVFilterLink.srcpic    ->  AVFilterLink.src_buf
AVFilterLink.cur_pic   ->  AVFilterLink.cur_buf
AVFilterLink.outpic    ->  AVFilterLink.out_buf

The new names are more generic and more consistent, since the struct
they contain, which was named AVFilterPicRef, has been renamed to
AVFilterBufferRef.

avfilter_copy_picref_props -> avfilter_copy_buffer_ref_props
AVFilterBufferRef.pic      -> AVFilterBufferRef.buffer

They have been renamed to allow sharing with audio.

The struct is going to be used for storing audio buffer references as
well, and the new name is more generic.

AVFilterBuffereRef in avfilter_default_get_video_buffer().

The error was being caused by the previous patch which resized
AVFilterBuffer's data and linesize arrays to 8.

The vorbis decoder doesn't handle more than one audio frame packed into
the same AVPacket, so they need to be split in the depacketizer.
