Some functions that lock things are void, so we just return early. Also make ossl_namemap_empty return 0 on error. Updated the docs, and added some code to ossl_namemap_stored() to handle the failure, and updated the tests to allow for failure. Fixes: #14230 Reviewed-by: Shane Lontis <shane.lontis@oracle.com> Reviewed-by: Paul Dale <pauli@openssl.org> (Merged from https://github.com/openssl/openssl/pull/14238)
