For historical reasons, pid_t & mode_t are defined as long instead
of int for 32-bit processes in the Solaris headers, and even though
they are the same size, gcc issues -Wformat headers if you try to
print them with "%d" and "%u" instead of "%ld" & "%lu".

This should test the limits of loading 4GB files on i386 platforms, such
as the Hurd CI runner. On such platforms, `sizeof(size_t) == 4`.
This should fix the compiler warning from

The tests - one for sync, one for async - create a sparse file for
this purpose, so this should be cheap on the fileystem.
Of course, the test still allocates >4GB of memory for the data that it
returns from g_file_load_contents(), I hope the CI test runners can deal
with that.
Disable tests that require update-desktop-database when it is missing.
It requires glib to build so it will be missing when bootstrapping glib.
Refactor the ifdef for Windows and MacOS while at it and reduce number
of ifdefs.

g_file_copy_async() and g_file_move_async() are written in a way that is
not bindable with gobject-introspection. The progress callback data can
be freed once the async callback has been called, which is convenient
for C, but in language bindings the progress callback closure is
currently just leaked.
There is no scope annotation that fits how the progress callback should
be treated:
- (scope call) is correct for the sync versions of the functions, but
incorrect for the async functions; the progress callback is called
after the async functions return.
- (scope notified) is incorrect because there is no GDestroyNotify
parameter, meaning the callback will always leak.
- (scope async) is incorrect because the callback is called more than
once.
- (scope forever) is incorrect because the callback closure could be
freed after the async callback runs.
This adds g_file_copy_async_with_closures() and
g_file_move_async_with_closures() for the benefit of language bindings.

As explained in the previous commit, GNU Coreutils 9.2 changes the behaviour
of `du --bytes` to only count regular files and symlinks.
The previous commit makes the test pass with GNU Coreutils >=9.2, but the
machine running the tests may have an older version, or perhaps even a
reimplementation such as uutils. So we can't rely on the size returned by `du`
to be the consistent across systems any more.
However, the plus side of the new behaviour is that the size reported by `du`
/ `G_FILE_MEASURE_APPARENT_SIZE` is now well-defined across filesystems
(as the sum of the sizes of regular files & symlinks), so we can hardcode it.

That’s what xdgmime uses for zero-sized files (see `XDG_MIME_TYPE_EMPTY`).
Historically, GLib explicitly used `text/plain` for empty files, to
ensure they would open in a text editor. But `text/plain` is not really
correct for an empty file: the content isn’t text because there is no
content. The file could eventually become something else when written
to.
Text editors which want to be opened for new, empty files should add
`application/x-zerosize` to their list of supported content types.
Users who want to set a handler for `application/x-zerosize` on their
desktop should use
```sh
gio mime application/x-zerosize # to see the current handler
gio mime application/x-zerosize org.gnome.gedit.desktop # to set it
```

`HAVE_COCOA` should be used only in the places where we’re actually
depending on the Cocoa toolkit. It should not be used as a general way
of detecting building on a Darwin-based OS such as macOS.
Conversely, there are a few places in the code where we do want to
specifically detect the Cocoa toolkit (and others where we specifically
want to detect Carbon), so keep `HAVE_COCOA` and `HAVE_CARBON` around.

This reverts commit 476e33c3f3.
We’ve decided to remove `G_OS_DARWIN` in favour of recommending people
use `__APPLE__` instead. As per the discussion on #2802 and linked
issues,
* Adding a new define shifts the complexity from “which of these
platform-provided defines do I use” to “which platform-provided
defines does G_OS_DARWIN use”
* There should ideally be no cases where a user of GLib has to use
their own platform-specific code, since GLib should be providing
appropriate abstractions
* Providing a single `G_OS_DARWIN` to cover all Apple products (macOS
and iOS) hides the complexity of what the user is actually testing:
are they testing for the Mach kernel, the Carbon and/or Cocoa user
space toolkits, macOS vs iOS vs tvOS, etc

In case the XDG database is not initialized yet we may try to sniff a
0-length data, making our content-type routines to mark non-empty files
as `application/x-zerosize`.
This is wrong, so in case the sniff size is not set, let's just
try to read the default value. To avoid false-application/x-zerosize
results (that are not something we want as per legacy assumptions).

While it's possible to create a directory synchronously via
g_dir_make_tmp(), there's no such API that performs it asynchronously.
So implement it using GFile, using a thread to perform such task.
The interface was ready for this API but it was not provided.
So implement this, using a thread that calls the sync API for now.
Add tests.

Since commit 87e19535fe, the ETag check when writing out a file through
a symlink (following the symlink) has been incorrectly using the ETag
value of the symlink, rather than the target file. This is incorrect
because the ETag should represent the file content, not its metadata or
links to it.
Fix that, and add a unit test.

`""` is not a valid path (`stat()` on it returns `ENOENT`). Previously,
a full `GLocalFile` was being created, which ended up resolving to

`ENXIO` can be returned from `open(2)` for special files (FIFOs, device

These test all the functionality and combinations of flags I can think
of. They do not cover dynamic behaviour (for example, what would happen

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.

Expose a function that prepares an attribute query string to be passed
to g_file_query_info() to get a list of attributes normally copied with
the file. This function is used by the implementation of
g_file_copy_attributes, and it's useful if one needs to split
g_file_copy_attributes into two stages, for example, when nautilus does
a recursive move of a directory. When files are moved from the source
directory, its modification time changes. To preserve the mtime on the
destination directory, it has to be queried before moving files and set
after doing it, hence these two stages.

Sometimes this test was timing out due to the file monitor notifications
taking longer than the arbitrary 2s delay before ending the test and
checking its results at the end of `iclosed_cb()`.
Avoid that timing-dependence by ending the test when the expected file
monitor notifications are seen, or after a 10s timeout (if so, the test
is failed).
This makes the test run 4× faster in the normal case, as it’s no longer
waiting for a timeout to elapse if the file monitor notifications come
in sooner.
