This introduces no functional changes, but reworks the array indexing so
that scan-build has a better idea about the array bounds. This squashes
the scan-build warning:
```

This will probably make no functional difference, but will squash two
warnings from scan-build:
```

It seems like a reasonable thing to warn about. Initialising the full
union to zero should avoid any possibility of undefined behaviour like
that.

This is a valid situation which can occur if the preceding

`max_priority`.

These `memcpy()` calls only happen if `g_inet_address_get_family(group)
== G_SOCKET_FAMILY_IPV4`, so the assertions should never fail.
It’s helpful for understanding the code, and for static analysis, to add
the assertions though.

Remove unused tests/timelooop.c and tests/timeloop-basic.c because
these programs are manual performance tests which are no more relevant
for glib. They were used for the writing of GMainLoop but since then
they haven't not much been used in 22 years, it is safe to remove them.
Helps issue #1434
The `struct timespec` type documented as being passed to the `futex()`
syscall actually needs to be the *kernel’s* timespec type. This will be
a different width from the userspace timespec type if running a 64-bit
userspace on a 32-bit kernel.
That mismatch will cause `g_cond_wait_until()` to return `FALSE`
immediately.
No other uses of `futex()` in GLib use the timeout argument, so they’re
all OK.
Following a detailed suggestion by Rich Felker, pass a different
timespec type into `futex()` if `__NR_futex_time64` is defined. That’s
the 64-bit time version of `futex()` which was added in kernel 5.1, and
which was only added for 32-bit kernels.

Inspired by https://gitlab.gnome.org/GNOME/glib/-/issues/2638.
This requires moving the tests to subprocesses, so that
`g_log_set_writer_func()` is only called once per process.
It also adds a test for the new error.

When I enabled unix socketpair test on win32, I left the existing
g_close(fds[1]), but _g_win32_socketpair() returns native sockets
descriptors that must be closed with closesocket() on win32.

...for certain Windows locales, since the formats accepted for
g_date_set_parse() will vary depending on the current system locale. For
instance, g_date_set_parse(gdate, "dd/mm/yy") is accepted on locales such
as zh-HK (Chinese (Hong Kong SAR)) but is rejected on zh-TW (Chinese
(Taiwan)).
One can tell from the "date format" settings in the Windows system
control panel whether there is a "dd/MM/YYYY" or "dd/MM/YY" option from the
drop-down list of date formats to display for the locale, which will indicate
whether g_date_set_parse(gdate, "dd/mm/yy") is accepted, which is true for
zh-HK but is not true for zh-TW.
If g_date_set_parse(gdate, "dd/mm/yy") is not accepted, try again with
g_date_set_parse(gdate, "yy/mm/dd") thereafter for the 2-digit-year tests.
When checking that the connection has the expected number of refs, the
test would block on a `GMainContext` iteration for up to 3s before
waking up and failing (if the refcount was still not as expected).
This check was written in the expectation that changing the refcount of
the connection would only happen due to dispatching a source on
`GMainContext` — hence the `GMainContext` would wake up as the refcount
changed.
That’s probably not actually true though. It might be the case that the
connection’s refcount is changed on from the GDBus worker thread, which
would not cause any wakeups on the main thread’s `GMainContext`.
In this case, the `GMainContext` iteration in
`assert_connection_has_one_ref()` would block for the full 3s, and then
wake up and notice the refcount is correct (then the test would
proceed).
That’s fine, apart from the fact that `test_threaded_singleton()` does
this 1000 times. If the slow case is hit on a significant number of
those test runs, the test will take around 3000s to complete, which is
significantly more than meson’s test timeout of 360s. So the test fails
with something like:
```

```
From this log, it can be seen that the sleep is happening on a different
`GMainContext` every other time, so the test *is* making progress.
Assuming this is a correct diagnosis (it’s a lot of guessing), this
commit tries to fix the test by adding a wakeup timeout to the
`GMainContext` in `assert_connection_has_one_ref()`, which will wake it
up every 50ms to re-check the exit condition.
This polling approach has been taken because it doesn’t seem feasible to
make sure that every `g_object_ref()`/`g_object_unref()` call on a
`GDBusConnection` causes the main context to wake up.
