Comment (by nickm):

 These functions are replaced by no-ops in OpenSSL 1.1:
 {{{
 CRYPTO_cleanup_all_ex_data
 ENGINE_cleanup
 ERR_free_strings
 EVP_cleanup
 }}}

 These are replaced with variants of `OPENSSL_init_crypto()`:
 {{{
 ERR_load_crypto_strings
 OpenSSL_add_all_algorithms
 }}}

 These are replaced with variants of `OPENSSL_init_ssl()`:
 {{{
 SSL_library_init
 SSL_load_error_strings
 }}}

 These have new names:
 `EVP_CIPHER_CTX_cleanup()` becomes `EVP_CIPHER_CTX_reset()`.
 `X509_get_notAfter()` becomes `X509_get0_notAfter` or
 `X509_getm_notAfter`.
 `X509_get_notBefore()` becomes `X509_get0_notBefore` or
 `X509_getm_notBefore`.
