95568c4e31 avfilter/scale2ref: deprecate in favor of scale=rw:rh 
And remove it from the documentation.

bb80445813 avfilter/vf_scale: add optional "ref" input 
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.

c3ca90a92e avcodec/x86/vp3dsp_init: Set correct function pointer, fix crash 
Regression since fd172185580c1ccdcfb90bbfdb59fa806fad3117;
triggered by vp4/KTkvw8dg1J8.avi in the FATE suite, but not
when running fate as this code is not used when the bitexact
flag is set.

Bisecting done by ami_stuff, patch from user Mika Fischer

9fb3d640fb avcodec/av1dec: Always set ret before goto end 
Before 0f8763fbea, av1_frame_ref()
and update_reference_list() could fail and therefore needed to
be checked, which incidentally set ret. This is no longer happening,
leading to a potential use of an uninitialized value which is
also the subject of Coverity ticket #1596605.

Fix this by always setting ret before goto end; do not return
some random ancient value.

71669f2ad5 avcodec/libx264: bump minimum required version to 155 
This version is seven years old, and present in Debian oldoldstable,
Ubuntu 20.04 and Leap 15.0.

Allows cleaning up the file substantially. In particular, this is
motivated by the desire to stop relying on init_static_data.

578ac59887 lavfi/qsv: Copy metadata fields from the given input 
Currently it always copies the metadata fields from the last input when
there are multiple inputs for the filter. For example, the metadata
fields from input1 are copied to the output for overlay_qsv filter,
however for regular overlay filters, the metadata fields from input0 are
copied to the output. With this fix, we may copy the metadata fields
from input0 to the ouput as well.

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
