Verify that the checkpoint requested by an incremental backup exists.
Unfortunately validating whether the checkpoint configuration actually
matches the disk may not be reasonably feasible as the disk may have
been renamed/snapshotted/etc. We still rely on bitmap presence.

The virGDBusBusInit is supposed to return a reference to
requested bus type (system/session) or, if non-shared bus is
requested then create a new bus of the type. As an argument, it
gets a double pointer to GError which is passed to all g_dbus_*()
calls which allocate it on failure. Pretty standard approach.
However, since it is a double pointer we must dereference the
first level to see if the value is NULL. IOW:

In case of iterators, we adapt the existing API of iterators to glibs to
