commit ce925927fdcc5e41f1a8975f31405f913a6583d1
Author: Kurt Garloff <kurt@garloff.de>
Date:   Wed Feb 28 22:49:18 2024 +0100

    Adjust struct _evp_cipher_ctx_st to openssl-3.0.6+.
    
    This is only done if the version is indeed >= 3.0.6.
    It's only relevant on 32bit, as the alignment rules on 64bit
    do hide this difference.
