	Bug 523298 - win_iconv can't convert from UTF-8 to GB18030 (or vice versa)

	* glib/win_iconv.c: Fixes for code page 54936 (GB18030)
	(mbtowc_flags): New function. Check if a code page is one of those
	for which the dwFlags parameter to MultiByteToWideChar() must be
	zero. Return 0 or MB_ERR_INVALID_CHARS.
	(mbcs_mblen): New function for multi-byte (more than two bytes for
	some characters) code pages. Only handles 54936 for now.
	(make_csconv): Use it for 54936.
	(kernel_mbtowc): Use mbtowc_flags().
