EVP_cleanup is implemented in #10834; keep its stub here so the two
changes do not define it twice.

OPENSSL_add_all_algorithms_noconf, EVP_cleanup, OPENSSL_load_builtin_modules
and CONF_modules_free return without an observable effect, as LibreSSL
2.5.4 does through the exports: the name table and the configuration
module list they fill and empty are only read by calls that are not
exported or still throw. EVP_cleanup keeps objects added by OBJ_create,
because the deferred OBJ_cleanup only runs after a cipher or digest
with an added NID was registered.

X509_STORE_CTX_get_ex_data reads the context's ex_data stack, and
X509_STORE_CTX_get1_chain copies the chain stack and raises each
certificate's reference count. UI_set_result checks a prompt or verify
result against its bounds, queuing UI_R_RESULT_TOO_SMALL or _LARGE and
marking the UI redoable, copies it, or picks a boolean answer.
PKCS12_PBE_add, OBJ_cleanup and SSL_load_error_strings return without
an observable effect, as LibreSSL 2.5.4 does while no object is added
and no error string is read.
LibreSSL 2.5.4's only built-in engine, padlock, is compiled out by
OPENSSL_NO_HW_PADLOCK in both of its portable builds, and the module
exports no call that adds an engine, so the list stays empty.
ENGINE_get_first returns null and ENGINE_load_builtin_engines and
ENGINE_cleanup do nothing. ENGINE_by_id pushes ENGINE_R_NO_SUCH_ENGINE
for an id and ERR_R_PASSED_NULL_PARAMETER for null. ENGINE_get_next,
ENGINE_init, ENGINE_finish, ENGINE_free, ENGINE_ctrl, ENGINE_ctrl_cmd
and ENGINE_load_private_key push ERR_R_PASSED_NULL_PARAMETER for a null
engine, or for a null command name in ENGINE_ctrl_cmd, and return null
or 0. Every error uses LibreSSL's function code 0xfff. A non-null
engine throws, since none can exist.
