	* win32/gwinhttpfileoutputstream.c
	* win32/gwinhttpfileoutputstream.h: New files implementing
	GWinHttpVfs and related classes, a GVfs for HTTP and HTTPS URIs on
	Windows. The implementation uses the WinHttp API. Both reading and
	writing are supported, i.e. GET and PUT requests. When writing,
	each write call is done using a separate PUT request with a
	Content-Range header. Requests for file URIs and plain pathnames
	are forwarded to GLocalVfs.

	* win32/winhttp.h: Reverse engineered <winhttp.h>, borrowed from
	WINE. Used as there is no <winhttp.h> bundled with mingw, and
	requiring people to download the Windows SDK just for this one
	header is not reasonable.

	* win32/Makefile.am: Add above files.

	* giomodule.c: Call _g_winhttp_vfs_get_type() on Windows to set up
	the plumbing for the above.
