This filter uses the AVBuffer API to allocate buffers that are never
shared at all and frees them via av_freep() (actually, it passes
pointers to AVBufferRefs to av_freep, so that only the AVBuffer
structures are freed at all (because AVBufferRef has a AVBuffer* as its
first member), not the AVBufferRef and not the underlying buffers;
and due to a wrong check the AVBuffers corresponding
to buf_org[c] with c>0 were never freed at all). This is a violation
of the AVBuffer API and causes a memleak. Fix this by avoiding the
AVBuffer API altogether.
(The FATE tests don't catch this, because they use piping to awk,
so that the error code from ffmpeg is ignored.)

This patch is analogous to 20f9727018:
It hides the internal part of AVFilter by adding a new internal
structure FFFilter (declared in filters.h) that has an AVFilter
as its first member; the internal part of AVFilter is moved to
this new structure.
