When the file name is too long (for example, more than 238 bytes on
ext4), this will cause the creation of the .trashinfo file to fail.
Let's shorten the .trashinfo filename in this case, after all the
trash specification only requires unique filenames (see
`Contents of a trash directory` section in
https://specifications.freedesktop.org/trash-spec/trashspec-latest.html).
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
https://gitlab.gnome.org/GNOME/glib/-/jobs/3989442:
```

They take too long to include in a normal test run. They’ll still be run

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.
GByteArray is limited to 4GB in size and the current code silently
overflows when that happens.
Replace both load_contents() and load_contents_async() implementations
with a version that uses realloc() and gsize to maintain the array.
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.

Previously it was mapped (as a default) to `G_IO_ERROR_FAILED`.
It’s the error that macOS returns when trying to connect to a socket which
is bound but not listened to. Linux returns `ECONNREFUSED` in this case.
It’s helpful if they both map to the same `GIOError` value.
This should fix the `/socket-client/connection-fail` test on macOS,
which is currently
[failing](https://gitlab.gnome.org/GNOME/glib/-/jobs/3970547) with:
```

Once the task is completed (and `g_task_return_*()` has been called),
the task is no longer needed. It would make more sense to unref it in
`complete_connection_with_error()`, where `g_task_return_*()` is called,
but that complicates other call sites significantly, so I didn’t do it.

While backporting CVE-2024-34397 fixes I noticed that this comment
claimed that the reference count is immutable after construction, which
is clearly not true. In fact the reference count is the only
mutable field.

To avoid adding a large block of macros to gdbusprivate.h, I've only
added a subset of the well-known error names. I chose to draw the
line by adding constants for the errors emitted via their string names
in GDBusConnection, but not for error names that are only mentioned
in `gdbuserror.c` or in tests.

Most D-Bus interfaces are domain-specific, but these interfaces from the
D-Bus Specification are intended to be commonly used in any context for
which they are found to be appropriate.
Most of these use `gdbusprivate.h`. One exception is that
`gio/tests/gdbus-example-*` redefine the constants locally: due to these
files' dual role as part of the unit tests and as sample code, it seems
desirable to ensure that they can still be compiled outside GLib.

These well-known flags and replies are part of the D-Bus Specification,
and also exist with the same names in libdbus header files.
Moving them into a private header means that unit tests like
gdbus-proxy-threads and gdbus-subscribe don't have to reinvent them.

Unlike the various functions to call D-Bus methods, these sort their
arguments in a non-obvious order (bus name, interface, signal, path),
presumably aiming to sort the most-likely-to-be-used arguments first.

This test was subscribing to the NameOwnerChanged signal with an
incorrect object path, so the callback would never be called. In this
particular case it doesn't actually matter, because the callback does
nothing anyway (the purpose of this particular test was to test that
the user-data is freed on unsubscription).

Almost identically to the previous commit, fix a similar latent bug in
`g_dbus_connection_export_action_group()`, which was not ready to handle
the fledgling `GActionGroupExporter` being freed early on an error
handling path.
See the previous commit message for details of the approach.
This includes a unit test.

Fixes: #3366
This latent bug wasn’t triggered until commit 3f30ec86c (or its
cherry-pick onto `glib-2-80`, 747e3af99, which was first released in
2.80.1).
That change means that `g_menu_exporter_free()` is now called on the
registration failure path by `g_dbus_connection_register_object()`
before it returns. The caller then tries to call `g_slice_free()` on the
exporter again. The call to `g_menu_exporter_free()` tries to
dereference/free members of the exporter which it expects to be
initialised — but because this is happening in an error handling path,
they are not initialised.
If it were to get any further, the `g_slice_free()` would then be a
double-free on the exporter allocation.
Fix that by making `g_menu_exporter_free()` robust to some of the
exporter members being `NULL`, and moving some of the initialisation
code higher in `g_dbus_connection_export_menu_model()`, and removing the
duplicate free code on the error handling path.
This includes a unit test.

It's an array containing the list of sanitizers in use, normally it
contains a value, but in some cases may have more than one (e.g.
'address' and 'undefined').
And so use it to avoid repeated checks
In glocalfile we're allocating some temporary strings but we don't free
them on early returns, so free them once done and unset the variables
to prevent them being used incorrectly.
It looks like that finally also valgrind notices the same leaks as
address sanitizer does. It does it more randomly but it still happens,
so better to inform about until #2309 is resolved.
