For the reasons given in the new bit of documentation, GDBusProxy should
not be used for connecting to stateless D-Bus services which may be
restarted at any point.

Include the base URI in the `g_test_bug()` calls instead. This resolves
inconsistencies between the old bug base (bugzilla.gnome.org) and the
new bug base (gitlab.gnome.org). It also has the advantage that the URI
passed to `g_test_bug()` is now clickable in the code editor, rather
than being split across two locations.

Since commit ab285899a6 ('gdbusconnection: Document main context
iteration for unsubscript'), we document when the user is guaranteed
that all resources are gone after g_dbus_connection_signal_unsubscribe().
This is not merely an implementation detail, it's something that the
user needs to be able to rely on. It is good that this is documented.
However, libnm does something different ([1]). It registers to several D-Bus
signals without providing a GDestroyNotify. After unsubscription, it schedules
another idle action with lower priority and uses that to know when
cleanup is complete. I think this is a useful alternative and should
also be guaranteed and documented to work.
Also note that this isn't just some implementation detail that currently
happens to work. GDBusConnection tightly integrates with GMainContext and it
works by scheduling idle sources with G_PRIORITY_DEFAULT priority. It needs to
schedule all events with this same priority, otherwise the ordering is not
preserved. At this point, with GDBusConnection working this way, this is no longer
something that can reasonably be any different. It's how GDBusConnection fundamentally
works, and a user must be able to rely on that. As such, this new promise isn't
something that we would want to break in the future.
Thus document it.

This fixes a bug where the family flag was ignored in lookup_data_new,
causing the resolver to call getaddrinfo with no hints set when clearly
the family hint should have been set.

An application that has been shut down is still marked as registered
even if its implementation has been already destroyed.
This may lead to unguarded crashes when calling functions that have
assumptions for being used with registered applications.
So, when an application is registered, mark it as unregistered just
before destroying its implementation and after being shut down, so that
we follow the registration process in reversed order.
