As it turns out, we have examples of internal functions called
type_name_get_private() in the wild (especially among older libraries),
so we need to use a name for the per-instance private data getter
function that hopefully won't conflict with anything.
Previously, g_file_copy() would (on Unix) create files with the
default mode of 644. For applications which might at user request
copy arbitrary private files such as ~/.ssh or /etc/shadow, a
world-readable copy would be temporarily exposed.
This patch is suboptimal in that it *only* fixes g_file_copy()
for the case where both source and destination are instances of
GLocalFile on Unix.
The reason for this is that the public GFile APIs for creating files
allow very limited control over the access permissions for the created
file; one can either say a file is "private" or not. Fixing
this by adding e.g. g_file_create_with_attributes() would make sense,
except this would entail 8 new API calls for all the variants of
_create(), _create_async(), _replace(), _replace_async(),
_create_readwrite(), _create_readwrite_async(), _replace_readwrite(),
_replace_readwrite_async(). That can be done as a separate patch
later.

There are two benefits to this:
1) We can centralize any operating system specific knowledge of
close-vs-EINTR handling. For example, while on Linux we should never
retry, if someone cared enough later about HP-UX, they could come by
and change this one spot.
2) For places that do care about the return value and want to provide
the caller with a GError, this function makes it convenient to do so.
Note that gspawn.c had an incorrect EINTR loop-retry around close().

Non-technical users won't know that "stating" refers to stat(2), so we
just use "error when getting information" now.

- Fix various #include issues
- Change #error to #warning for the EXTERNAL authentication mechanism.
It is not clear if this should work on Win32 at all.
- Call close() before unlink() for the SHA1 keyring
- Change #error to #warning so we don't forget to do
permission checking of the .dbus-keyrings directory
- Use Win32 SID for the SHA1 auth mech
- Apparently we can't use word 'interface' as an identifier
- Implement a _g_dbus_win32_get_user_sid() function. For now it's
private. Don't know if it should be public somewhere. Maybe in
a future GCredentials support for Win32? I don't know.
- GFileDescriptorBased is not available on Win32. So avoid using
it in GLocalFile stuff. Now, Win32 still uses GLocalFile + friends
(which works with file descriptors) so expose a private function
to get the fd for an OutputStream so things still work.
- Fixup gio.symbols
- Fixup tests/gdbus-peer.c so it builds
With this, at least things compile and the gdbus-peer.exe test case
passes. Which is a great start. I've tested this by cross-compiling on
a x86_64 Fedora 13 host using mingw32 and running the code on a 32-bit
Windows 7 box.

Previous code used g_mkstemp(). But when using
G_FILE_CREATE_REPLACE_DESTINATION, no attempt was made to ensure proper
mode and flags of the created temporary file. The visible issue was that
the file was always created with mode 0600 as opposed to using 0666.
(The invisible issue was that O_RDWR was used instead of O_WRONLY.)
This implements all the GIOStream file ops for local files.
We use the "fallback to output stream" for all GFileIOStream ops.
Some helpers stuff was added to the local input and output streams
so they could be reused.

Bug 548988 - g_file_replace fails on Windows when the target file
exists already
* glocalfileoutputstream.c (g_local_file_output_stream_close): On
Windows, close the file before renaming it (in case we have been
writing to a file with a temporary name).
(g_local_file_output_stream_close, handle_overwrite_open): Use
GLocalFileStat instead of plain struct stat, for passing to
_g_local_file_info_create_etag(). Thus also use _fstati64()
instead of plain fstat() on Windows.
