commit 300e6d4116f956b035281ec94297dc4dc8d4e1d3 upstream.

Couple error handling helpers are repeated in both tools, so move them to a common header.

commit 467d60eddf55588add232feda325da7215ddaf30 upstream.

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.

commit 558bdc45dfb2669e1741384a0c80be9c82fa052c upstream.

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It has been superseded by the PROVIDER API, so use it instead for OPENSSL MAJOR 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.
