This is automatically enabled if the width/height expressions reference
any ref_* variable. This will ultimately serve as a more principled
replacement for the fundamentally broken scale2ref.

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.

This adds an AVOption to respect that header.

Before commit f025b8e110,
every frame-threaded decoder used ThreadFrames, even when
they did not have any inter-frame dependencies at all.
In order to distinguish those decoders that need the AVBuffer
for progress communication from those that do not (to avoid
the allocation for the latter), the former decoders were marked
with the FF_CODEC_CAP_ALLOCATE_PROGRESS internal codec cap.
Yet distinguishing these two can be done in a more natural way:
Don't use ThreadFrames when not needed and split ff_thread_get_buffer()
into a core function that calls the user's get_buffer2 callback
and a wrapper around it that also allocates the progress AVBuffer.
This has been done in 02220b88fc
and since that commit the ALLOCATE_PROGRESS cap was nearly redundant.
The only exception was WebP and VP8. WebP can contain VP8
and uses the VP8 decoder directly (i.e. they share the same
AVCodecContext). Both decoders are frame-threaded and VP8
has inter-frame dependencies (in general, not in valid WebP)
and therefore the ALLOCATE_PROGRESS cap. In order to avoid
allocating progress in case of a frame-threaded WebP decoder
the cap and the check for the cap has been kept in place.
Yet now the VP8 decoder has been switched to use ProgressFrames
and therefore there is just no reason any more for this check
and the cap. This commit therefore removes both.
Also change the value of FF_CODEC_CAP_USES_PROGRESSFRAMES
to leave no gaps.

This allows one complex filtergraph's output to be sent as input to
another one, which is useful in certain situations (one is described in
the docs).
Chaining filtergraphs was already effectively possible by using a
wrapped_avframe encoder connected to a loopback decoder, but it is ugly,
non-obvious and inefficient.
