87cc213748 avformat/hevc: don't print parameter_set_id for any NALU 
It's not a value stored in the hvcC structure.
Fixes use of uninitialized variable errors under sanitizer when the input extradata is
already hvcC formatted, given we don't parse parameter sets for those.

080dc4cf54 avformat/tls_openssl: load default verify locations 
When no explicit CAs file is set, load the default locations,
else there is no way for verification to succeed.

This matches the behavior of other TLS backends.

c62813a057 avfilter/x86/vf_colordetect: make the AVX512 functions run only on ICL targets or newer 
For detect_range, the usage of vpbroadcast{b,w} requires the AVX512BW extension, and for
detect_alpha we don't want ZMM instructions downclocking old CPUs.

545f721b44 avfilter/vf_colordetect: add new color range detection filter 
This filter can detect various properties about the image, including
whether or not there are out-of-range values, or whether the input appears
to use straight or premultiplied alpha.

Of course, these can only be heuristics, with "undetermined" as the base
case. While we can definitely prove the existence of full range or
straight alpha colors, we can never infer the opposite.
