......................................................................

ssl_verify_openssl: use official ASN1_STRING_ API

ASN1_STRING are now opaque types in OpenSSL 4.x — the internal data and
length fields are no longer directly accessible. Use the accessor API
instead. Accessors have been available since OpenSSL 1.1.0

The ASN1_STRING_length accessor is already in use, but not consistently
applied. Standardise on using ASN1_STRING_length and ASN1_STRING_get0_data
which allows for successful build of OpenSSL 4.x
