This is the result of checking each `Returns:` line in these files. I’ve
only considered nullability and not other (potentially missing or
incorrect) annotations.

If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.
It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.
Previously this would cause an assertion failure when checking the paths
of exported objects, as it would try to check that their paths started
with ‘//’ due to mishandling the root object case.
Includes a unit test.

The previous commit introduced a possible memory leak in cases
where we get a G_IO_ERROR_CLOSED error. Make sure to always
free an error, if we got one.

There are real world cases where emitting signals can fail, such
as if the DBus connection closes. Asserting and aborting the process
in these cases is just plain lazy.
Ignore the errors when the connection is closed, and turn the
others into warnings.

As it turns out, we have examples of internal functions called
type_name_get_private() in the wild (especially among older libraries),
so we need to use a name for the per-instance private data getter
function that hopefully won't conflict with anything.
Otherwise we might collide with an interface called Connection.

This is for the same reason that GDBusProxy has its properties
prefixed with g-.

In registration_data_export_interface(), the object_path is obtained using:
object_path = g_dbus_object_get_object_path (G_DBUS_OBJECT (data->object));
But when exporting an object uniquely, the object_path is not assigned
to the GDBusObject until after all the interfaces are exported.
Therefore, registration_data_export_interface() is trying to export
the interface on the non-unique object path, which can lead to
run-time errors if an object already exists on that path.
Instead, registration_data_export_interface() should be passed the
object_path explicitly, as is done in
g_dbus_object_manager_server_export_unlocked().

.. and add a C setter to do this. Also make the C getter return a
reference since the property may be set from another thread. Also
change the constructor to _not_ take a GDBusConnection since this is
something you almost always want to do _after_ creating it. The
API/ABI break is fine as there has never been a GLib release with this
type.
