3769968afd fftools/ffprobe: fix printing side data components and pieces 
Components and pieces are side data specific fields and there's a variable

They also need to be identified in some form, so print a type too.

44620ade25 fftools/ffmpeg_mux_init: Fix attachment_filename use-after-free 
The filename is freed with the OptionsContext and therefore
there will be a use-after-free when reporting the filename
in print_stream_maps(). So create a copy of the string.

This is a regression since 8aed3911fc.
fate-lavf-mkv_attachment exhibits it (and reports a random nonsense
filename here), but this does not make the test fail (not even with
valgrind; only with ASAN, as it aborts on use-after-free).

1e7d2007c3 all: use designated initializers for AVOption.unit 
Makes it robust against adding fields before it, which will be useful in
following commits.

Majority of the patch generated by the following Coccinelle script:

@@
typedef AVOption;
identifier arr_name;
initializer list il;
initializer list[8] il1;
expression tail;
@@
AVOption arr_name[] = { il, { il1,
- tail
+ .unit = tail
}, ...  };

with some manual changes, as the script:
* has trouble with options defined inside macros
* sometimes does not handle options under an #else branch
* sometimes swallows whitespace

c619d20906 fftools/ffplay: constrain supported YUV color spaces 
SDL supports only these three matrices. Actually, it only supports these
three combinations: BT.601+JPEG, BT.601+MPEG, BT.709+MPEG, but we have
no way to restrict the specific *combination* of YUV range and YUV
colorspace with the current filter design.

See-Also: https://trac.ffmpeg.org/ticket/10839

Instead of an incorrect conversion result, trying to play a YCgCo file
with ffplay will simply error out with a "No conversion possible" error.

filter that can't support it. Also fixes an error related to this
missing metadata from buffersrc (since commit 2d555dc82d)

0d00e2e2f7 fftools/ffmpeg_dec: eliminate all remaining InputStream uses 
Previously, the demuxer would register decoder with the scheduler, using
InputStream as opaque, and pass the scheduling index to the decoder.

Now the registration is done by the decoder itself, using DecoderPriv as
opaque, and the scheduling index is returned to demuxer from dec_open().

decoder_thread() then no longer needs to be accessed from outside of
ffmpeg_dec and can be made static.

ae06111d74 fftools/ffmpeg_demux: implement -bsf for input 
Previously bitstream filters could only be applied right before muxing,
this allows to apply them right after demuxing.

6cb7295abf fftools/ffmpeg_demux: add demuxing thread private data

2ee1c6ffb2 fftools/ffmpeg_demux: set options on codec parameters rather than decoder 
This avoids the requirement to always have a decoder context.

7e33534506 fftools/ffmpeg_demux: do not set bitexact directly on the decoder 
Add it to decoder options instead, to be processed when opening the
decoder. This way it won't be overridden by flags the user might be
setting otherwise.

564a15b2ee fftools/ffplay_renderer: Add device selection support 
The device can be selected by GPU name or index. For example,

ffplay -hwaccel cuda \
	-vulkan_params device="NVIDIA GeForce RTX 3060" \
	foo.mp4

ffplay -hwaccel cuda -vulkan_params device="0" foo.mp4

Please note that select device by index only supported by hwcontext,
not by libplacebo.

90bef6390f fftools/ffmpeg_filter: log an information message about filter graph reconfigurations 
Filter graph reconfigurations can cause nontrivial issues, e.g. PTS
discontinuities, so it is better to warn the user about them.
