Don't write the Content-Length header ourselves, WinHttpSendRequest()

2008-08-13  Tor Lillqvist  <tml@novell.com>

	* win32/gwinhttpfileoutputstream.c
	(g_winhttp_file_output_stream_write): Don't write the
	Content-Length header ourselves, WinHttpSendRequest() takes care
	of that when the dwTotalLength parameter is non-zero. Increment
	offset by the number of actual bytes sent, although I wonder if
	such a scenario is possible where less than requested would be
	sent and accepted by the server without errors.
