This function can cause significant delays when the mounted volume
is disconnected or just weird. Use IExtractIconW::GetIconLocation()
instead.
Theoretically, this should require COM to be initialized, but in my tests
this code worked just fine without calling CoInitializeEx().
On Windows gio runs a thread to update appinfo at startup.
If someone unloads gio (this happens when a dynamic gio module gets
unloaded by a program that doesn't use gio itself), there doesn't seem
to be a way to detect that until gio is already gone, and as soon as
gio is gone, the thread crashes, since it tries to execute instructions
that are no longer there.
Holding an extra reference to gio DLL fixes this, but it also prevents
gio from being unloaded, and there's no "weak references" for DLLs.
So we just pin gio and acknowledge that it will never be unloaded.

1) Check that schedule_call_in_idle code branch of gdbusnamewatching.c
is working to call vanished handler in the thread which had watched the name
2) Check cancellation of vanished handler if the name is unwatched before
vanished callback is dispatched.

After the recent reworking of this code it was possible for `g_close()`
to be called on `fd == -1`, which is invalid. It would have reported an
error, were errors not ignored. So it was harmless, but still best to
fix.
Simplify the error handling by combining both error labels and checking
the state of `fd` dynamically.

The variable `gconstructor_code` (which is what’s defined by
`gconstructor_as_data_h`) is not used at all inside
`glib-compile-schemas`.
This looks like a copy/paste error from the build definition for
`glib-compile-resources` below, which does need it.

In the 2.68 cycle we’d added 3 new enumerator elements. Due to the
preceding commit, they can now be annotated with
`GLIB_AVAILABLE_ENUMERATOR_IN_2_68`, which will make it a bit easier for
third party projects to notice when they’re using these symbols without
having bumped their GLib dependency.

`""` is not a valid path (`stat()` on it returns `ENOENT`). Previously,
a full `GLocalFile` was being created, which ended up resolving to
`$CWD`, through path canonicalisation. That isn’t right.
Fix it by creating a `GDummyFile` instead, and adding a unit test.

Calling `dlopen()` with `libutil.so` makes the installed tests depend on
having glibc's development files installed. To avoid this, we can work
out the runtime library name at build time and `dlopen` that instead.
This approach is [taken from libfprint][1], thanks to Marco Trevisan.

`ENXIO` can be returned from `open(2)` for special files (FIFOs, device
files and domain sockets) which are not backed by anything.
This fixes the error returned by `g_file_replace()` when trying to
replace such a file, so that it now matches the documentation.

These test all the functionality and combinations of flags I can think
of. They do not cover dynamic behaviour (for example, what would happen
if the source file is deleted by another process part-way through a call
to `g_file_replace()`).

The `G_FILE_CREATE_REPLACE_DESTINATION` flag is equivalent to unlinking
the destination file and re-creating it from scratch. That did
previously work, but in the process the code would call `open(O_CREAT)`
on the file. If the file was a dangling symlink, this would create the
destination file (empty). That’s not an intended side-effect, and has
security implications if the symlink is controlled by a lower-privileged
process.
Fix that by not opening the destination file if it’s a symlink, and
adjusting the rest of the code to cope with
- the fact that `fd == -1` is not an error iff `is_symlink` is true,
- and that `original_stat` will contain the `lstat()` results for the
symlink now, rather than the `stat()` results for its target (again,
iff `is_symlink` is true).
This means that the target of the dangling symlink is no longer created,
which was the bug. The symlink itself continues to be replaced (as
before) with the new file — this is the intended behaviour of
`g_file_replace()`.
The behaviour for non-symlink cases, or cases where the symlink was not
dangling, should be unchanged.
Includes a unit test.

When GLib code is checked out with Windows line endings (happens on Windows),
data-to-c.py embedded that line endings into generated string literal. And
then they translated to double newlines in glib-compile-resources output.
clang-cl failed to compile such files because of empty lines in the middle of
multiline macros:
#define G_MSVC_CTOR(_func,_sym_prefix) \
static void _func(void); \
To fix the issue, enable 'universal newlines' mode when reading the input in
data-to-c.py - translate both '\n' and '\r\n' to '\n'.

This will require distributions to ensure they pass
`--localstatedir=/var` correctly to Meson, but they should be doing that
already.
See https://mesonbuild.com/Builtin-options.html#directories for details
about how Meson treats `localstatedir` differently from most other `dir`
variables.

It’s unlikely that the machine ID will be invalid (it’s system
configuration), but it would be helpful to not propagate invalid IDs
further, since a lot of things rely on it.
It’s not easy to test this (it requires factoring out the code so it can
be used from a test program, or allowing it to load a machine ID from a
custom path), so I haven’t added unit tests. I’ve tested manually by
overriding the loaded machine ID.

For non-Linux UNIX systems, the label 'close_libutil:' in
'test_pollable_unix_pty()' will have no statement that goes with that
label. Just do a 'return' on non-Linux UNIX systems.
