Use C-style backslash escaping to sanitize non-UTF-8 strings. The functions are compatible with glib's g_strcompress() and g_strescape(). The difference is only that g_strescape() escapes all non-printable, non ASCII character as well, while nm_utils_str_utf8safe_escape() -- depending on the flags -- preserves valid UTF-8 sequence except backslash. The flags allow to optionally escape ASCII control characters and all non-ASCII (valid UTF-8) characters. But the option to preserve valid UTF-8 (non-ASCII) characters verbatim, is what distinguishes from g_strescape().
