	* gconvert.c (open_converter): make static

	* gutf8.c (g_utf8_validate): Simplify logic a bit, maybe
	speeding it up - now we just return FALSE if we had to bail out
	for any reason before getting to the end of the string, as defined
	by a nul byte if len was -1, defined by the len otherwise. This
	also fixes a bug where nul bytes were not treated as invalid
	when the length was specified.
