Because of ffio_ensure_seekback() a seek error normally should only happen if
the end of file is reached during checking for the junk run-in. Also use proper
error code.

We are protecting the checked buffer with ffio_ensure_seekback(), so if the
inner check fails with a seek error, that likely means the end of file was
reached when checking for the next frame. This could also be the result of a
wrongly guessed (larger than normal) frame size, so let's continue the loop
instead of breaking out early. It will end sooner or later anyway.

Otherwise the subsequent ffio_ensure_seekback calls destroy the buffer of the
earlier. The worst case ~66kB seekback is so small it is easier to request it
entirely.
Fixes ticket #10837, a regression since
0d17f5228f.

Its existence is a remnant of (libavcodec's) lock-manager API
which has been removed in a04c2c707d.
There is no need to use the same lock for avisynth, chromaprint
or tls, so switch to ordinary static mutexes instead.

Before this patch, the implementation of pipe: inputs/outputs would
silently fall back to stdin/stdout for any argument not successfully
parsed by strtol().
This patch introduces an explicit error for any non-numerical arguments,
which should avoid user confusion as in #10977.
New behavior:
$ cat /tmp/video.mkv | ./ffmpeg -i pipe:aa -acodec copy -vcodec copy -f matroska pipe:1 | cat >/tmp/out.mkv
[pipe @ 0x5618c7bcf740] Non-numerical argument "aa" to pipe:
[in#0 @ 0x5618c7bced00] Error opening input: Invalid argument
Error opening input file pipe:aa.
Error opening input files: Invalid argument
Based on the patch of Nils Goroll <nils.goroll@uplex.de>.

sc->data_size may contain the size of a single fragment after probing, and
using it alongside the duration of the entire stream to calculate bitrate
will result in a bogus small value.

429 and 503 codes can, and often do (e.g. all Google Cloud
Storage URLs can), return a Retry-After header with the error,
indicating how long to wait, asd either a date, or in seconds,
before retrying again. If it is not respected by, for example,
using our default backoff stratetgy instead, chances of success
are very unlikely.
Some references:
* https://datatracker.ietf.org/doc/html/rfc6585
* https://datatracker.ietf.org/doc/html/rfc7231#section-7.1.3
This adds an AVOption to respect that header.

The existing option only allows users to set the max delay for a
single attempt, rather than the total allowed delay, which is both
pretty unintitive, and only applicable when exponential backoff is
used.
The default for this option is set to 256, which is just above the
effective total delay accomplished by the the existing
reconnect_delay_max default of 120.

If the demuxer doesn't set extradata in the stream's codecpar, a
need_context_update request will delete the previously extracted extradata in
the stream's internal AVCodecContext.
As we can't ensure the old extradata is valid for the stream in its post
context update request state, try to get extradata from the new packet instead
of attempting to preserve the old in some form.

Since this is guarded behind strict unofficial, we should warn if the
user feeds a dolby vision stream to this muxer, as it will otherwise
result in a broken file.
Some files with no image items have them, and were working prior to the recent
HEIF parsing overhaul.
Ignore such boxes instead, to recover the old behavior.
