81a454237d gwinhttpfile: Avoid arithmetic overflow when calculating a size
The members of `URL_COMPONENTS` (`winhttp_file->url`) are `DWORD`s, i.e.
32-bit unsigned integers. Adding to and multiplying them may cause them
to overflow the unsigned integer bounds, even if the result is passed to
`g_memdup2()` which accepts a `gsize`.

Cast the `URL_COMPONENTS` members to `gsize` first to ensure that the
arithmetic is done in terms of `gsize`s rather than unsigned integers.

Spotted by Sebastian Dröge.

73b293fd30 gio: Use g_memdup2() instead of g_memdup() in obvious places
Convert all the call sites which use `g_memdup()`’s length argument
trivially (for example, by passing a `sizeof()`), so that they use
`g_memdup2()` instead.

In almost all of these cases the use of `g_memdup()` would not have
caused problems, but it will soon be deprecated, so best port away from
it.

6f9b379c08 gwinhttpfile: Set display-name attribute on file info
It is not allowed to be `NULL` or unset if requested by the file
attribute matcher. Derive it from the basename. This doesn’t handle the
situation of a failed UTF-16 to UTF-8 conversion very well, but will at
least return something.

Note that the `g_filename_display_basename()` function can’t be used as
`GWinHttpFile` provides its URI in UTF-16 rather than in the file system
encoding.

This fixes a crash when using GIMP on Windows. Thanks to lillolollo for
in-depth debugging assistance.

4b0421a730 gwinhttpfile: Document constructor as potentially returning NULL
It can return NULL if the URI was badly encoded or couldn’t be handled
by Windows’ API.

d20e88fd11 gwinhttpfile.c: Fix build on Visual Studio
Visual Studio, at least the older versions, cannot use L on macros which
are defined as a constant string, plus the L must be applied to all string
literals here.  This does not look nice, but this is life...

2f575b95ac Bug 556415 - Crash on Windows 2000 in g_winhttp_vfs_init()
2008-11-12  Tor Lillqvist  <tml@novell.com>

	Bug 556415 - Crash on Windows 2000 in g_winhttp_vfs_init()

	* win32/gwinhttpvfs.h: Move the set of function pointers to
	winhttp.dll into a separate struct GWinHttpDllFuncs. Just have a
	pointer to that in the GWinHttpVfsClass.
	
	* win32/gwinhttpvfs.c: Move the lookup of functions from
	winhttp.dll into a function of its own, that stores the pointers
	in a separate GWinHttpDllFuncs variable. Add two bookeeping
	booleans lookup_done and funcs_found.

	Don't call g_io_extension_point_implement() to register the
	winhttp extension unless winhttp.dll has been successfully loaded
	and the required functions found in it.

	* win32/gwinhttp*.c: Adjust calls of the functions looked up from
	winhttp.dll correspondingly.

	Content-Length, Content-Type and Last-Modified.

	* win32/winhttp.h: Add some symbolic constants that are not
	publicly documented. Just a handful, so it should be OK to use
	information from the Windows SDK's headers.

	* 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.
