Don't export a matrix encoding side data when there's none signaled.
And if downmixing was handled by the decoder itself, then the downmix info does
not apply to the frame.

With this, if the eac3 dependent frame doesn't have coded downmix values when
parsed by ff_eac3_parse_header(), it will inherit the coded ones from the core
ac3 frame instead of ignoring them.

A flag in the codec header determines whether opcodes 0xfd/0xfe
are to be treated as special or not. The current code has 2
implementations of the same decoding scheme, with one treating
the 2 opcodes as special, the other not.
Collapse them into a single implementation and treat these opcode
according to the flag.

The reason for the failure is that the function yuv2rgb_1_c_template was modified
in 095f8038fa. The corresponding functional test
was added in c601bb8df5. The code on loongarch was
not updated in a timely manner, resulting in the error.

not for opaque file descriptors.
The code is written to allow using syncfiles later on.

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.
