	* glib/gstring.c (g_string_insert/append/prepend_unichar):
	Add functions to insert a unichar as UTF-8, since this
	is reasonably common.

	* glib/gutf8.c glib/gunicode.h (g_utf8_get_char_validated):
	New function exposing iterating through possibly invalid/incomplete
	UTF-8 to unicode to the outside world.

	* glib/gutf8.c (g_utf8_get_char_extended): Fix max_len argument
	to be gssize, not gsize.
