This will help static analysers which think that the type of
`priv->proxy_address` could potentially change between freeing
`dest_hostname` and the `g_return_if_fail()` call below, leading to the
code to continue through to `g_object_new()` and use `dest_hostname`
after freeing it.
This introduces no functional changes.

This should fix a scan-build warning that `resource` is
used-after-freeing in the final `g_resource_unref()` call in
`g_static_resource_fini()`, as `g_resources_unregister_unlocked()` has
already unreffed it.
In reality, each resource has two strong refs on it while active, so the
second unref is correct.

It is not only shorter than `not meson.is_cross_build() or
meson.has_exe_wrapper()` but also handle the case of cross compiling to
a compatible arch such as building for i386 on an amd64.

This will probably make no functional difference, but will squash two
warnings from scan-build:
```
../../../../source/glib/gio/gsocket.c:503:14: warning: Assigned value is garbage or undefined [core.uninitialized.Assign]
family = address.storage.ss_family;

../../../../source/glib/gio/gsocket.c:527:29: warning: Assigned value is garbage or undefined [core.uninitialized.Assign]
socket->priv->family = address.storage.ss_family;

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

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.

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.
Let GSocket handle the socket pair cleanup.

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.

While the assertion always turned out to be true on Linux, it frequently
caused spurious test failures on FreeBSD.
After some remote debugging, I *think* the cause is as written up in the
comment in the code in this commit. However, I cannot be certain, as the
more debugging messages I added, the harder the failure was to
reproduce; and I don’t have access to a FreeBSD machine.
This fixes failures like:
```
Bail out! GLib-GIO:ERROR:../gio/tests/converter-stream.c:1043:test_converter_pollable: assertion failed (error == NULL): Resource temporarily unavailable (g-io-error-quark, 27)
```
It’s succeeded 1000 times in a row on the FreeBSD CI now; previously
it was failing one time in three:

There’s (deliberately) a bit of race in implementing/handling
`CloseBeforeReturning()` in `gdbus-method-invocation.c`. If the server
closes the D-Bus connection early, the client may exit with `SIGTERM` if
`GDBusConnection:exit-on-close` is set. We don’t want that, as the test
is trying to check that the default handling of a D-Bus method return
after a connection has closed works.

G_GNUC_UNUSED does perfectly its job with gcc compiler but the warning
still remains with msvc compiler.
Once the unused variable removed, the finalize vfunc can be removed as
it's doing the same job as the parent function.
We must not open the fd with O_PATH|O_NOFOLLOW,
since the portal rejects that combination. Leaving
out O_NOFOLLOW is fine in this case - we know it
is a directory, we just received EISDIR.
