This is a per-file input option that adjusts an input's timestamps
with reference to another input, so that emitted packet timestamps
account for the difference between the start times of the two inputs.

Typical use case is to sync two or more live inputs such as from capture
devices. Both the target and reference input source timestamps should be
based on the same clock source.

If either input lacks starting timestamps, then no sync adjustment is made.

According to API docs avdevice_list_devices(), avdevice_list_input_sources()
and avdevice_list_input_sinks() should return the number of autodetected
devices on success. This is redundant with AVDeviceInfoList->nb_devices so it
was not noticed earlier that none of the underlying device list functions work
like that.

Let's fix it in generic code to make it in line with the API docs.

Fixes ticket #9820.

The output file (even the filesize) of the recently added
EXR tests depends on the endianness; therefore checksums
of these files must not be part of the ref file. Therefore
this commit adds an option (unused for now) to disable these
checksums on a per-test basis.

In order to avoid having to check twice, the checksum and
the filesize info are moved to immediately follow one another;
this results into updates to the ref files of all lavf-image tests.

FFmpeg removed it since it duplicated libswresample.

ts->req_sid could be set to a garbage value > 8192 on the first pass,
so keep the prior value, which is what the code did when it used a
pmt_filter variable that was part of the MpegTSContext.

…ts demuxer

I had fixed this previously, but the change must have been lost
in the move from utils.c to demux.c.

Its uses have been replaced with AV_SUBTITLE_FLAG_FORCED of
AVSubtitleRect::flags.

Attempting to upstream these changes revealed this with the
following addtional comments:
"sizeof(AVSubtitle) is part of the public ABI, no additions to it are
possible."

"[Using AVSubtitleRect::flags]
is also more correct, since in PGS for example you can have both
active rects that are forced, and those that are not, at the same
time."

They're not currently used, so they don't need to be there.
Vulkan stabilized the decode extensions less than a week ago, and their
name prefixes were changed from EXT to KHR. It's a bit too soon to be
depending on it, so rather than bumping, just remove these for now.

It was originally for a different function av_destruct_packet_nofree:
