utils: add osmo_escape_str()
To report invalid characters in identifiers, it is desirable to escape any weird characters. Otherwise we might print stray newlines or control characters in the log output. ctrl_test.c already uses a print_escaped() function, which will be replaced by osmo_escape_str() in a subsequent patch. control_cmd.c will use osmo_escape_str() to log invalid identifiers.
