tls: OPENSSL_fork_[prepare|parent|child] deprecated at openssl 3.0
From https://www.openssl.org/docs/man3.0/man3/OPENSSL_fork_prepare.html:
OPENSSL_fork_prepare, OPENSSL_fork_parent, OPENSSL_fork_child have been deprecated since OpenSSL 3.0.
These methods are currently unused, and as such, no replacement methods are required or planned.
OpenSSL has state that should be reset when a process forks. For example, the entropy pool used to generate random numbers (and therefore encryption keys) should not be shared across multiple programs. The OPENSSL_fork_prepare(), OPENSSL_fork_parent(), and OPENSSL_fork_child() functions are used to reset this internal state.
OPENSSL_init_crypto(3) will register these functions with the appropriate handler, when the OPENSSL_INIT_ATFORK flag is used
