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.

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.
When verification is enabled (using -tls_verify 1) now
the hostname will be verified properly too, while before
only other aspects of the certificate were checked.

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.

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.
The true problem happens in several previous get_vlc_symbol()
but checking that is more expensive (involving FFABS())
here its just a simple check between 2 variables we have.
