Components and pieces are side data specific fields and there's a variable
amount of them.
They also need to be identified in some form, so print a type too.

It is only used by ffprobe (once) and ffplay (twice);
inlining it avoids including it unnecessarily into ffmpeg.

Do not construct the name manually from input file/stream indices.
This is a step towards avoiding the assumption that filtergraph inputs
are always fed by demuxers.
The computation is based on demuxer properties, so that is the more
appropriate place for it. Filter code just receives the desired
start time/duration.
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).

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
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.

Instead of an incorrect conversion result, trying to play a YCgCo file
with ffplay will simply error out with a "No conversion possible" error.
This commit lets ffplay properly propagate YUV metadata into the filter
graph, avoiding such issues as e.g. accidentally passing YCgCo into a
filter that can't support it. Also fixes an error related to this
missing metadata from buffersrc (since commit 2d555dc82d)

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.
It is done based on demuxer information, so that is the more appropriate
place for this code.
This is a step towards decoupling Decoder and InputStream.
