Subject: sign-file,extract-cert: move common SSL helper functions to a header
Date: Fri, 12 Jul 2024 09:11:14 +0200
Couple error handling helpers are repeated in both tools, so
move them to a common header.

Subject: sign-file,extract-cert: avoid using deprecated ERR_get_error_line()
Date: Fri, 12 Jul 2024 09:11:15 +0200
ERR_get_error_line() is deprecated since OpenSSL 3.0.
Use ERR_peek_error_line() instead, and combine display_openssl_errors()
and drain_openssl_errors() to a single function where parameter decides
if it should consume errors silently.

Subject: sign-file,extract-cert: use pkcs11 provider for OPENSSL MAJOR >= 3
Date: Fri, 12 Jul 2024 09:11:16 +0200
ENGINE API has been deprecated since OpenSSL version 3.0 [1].
Distros have started dropping support from headers and in future
it will likely disappear also from library.
It has been superseded by the PROVIDER API, so use it instead
for OPENSSL MAJOR >= 3.
