'--with-smack-run-label' configuration is set, the smack label of each
CGROUP root directory should have the star (i.e. *) label. This is
mainly because current Linux Kernel set the label in this way.

However, if elogind has its own smack label and arg_join_controllers is
explicitly set or initialized by initialize_join_controllers() function,
current elogind creates the symlink in CGROUP root directory with its
own smack label as below.

(ordered alphabetically for better visibility)

This is grossly incorrect. The spec says that we're allowed to return
non-directed children, however, it does not allow us to return data
recursively in multiple parents. If we return "org", then we must not
return anything else that starts with "org/".

It is unclear, whether we can include child-nodes as a tree. Moreover, it
is usually not what the caller wants. Hence, this patch changes sd-bus to
never return introspection data recursively. Instead, only a single
child-layer is returned.

This patch relies on enumerators to never return hierarchies. If someone
registers an enumerator via sd_bus_add_enumerator, they better register
sub-enumerators if they support *TRUE* hierarchies. Each enumerator is
treated as a single layer and not filtered.
Enumerators are still allowed to return nested data. However, that data
is still required to be a single hierarchy. For instance, returning
"/org/foo" and "/com/bar" is fine, but including "/com" or "/org" in that
dataset is not.
This should be the default for enumerators and I see no reason to filter
in sd-bus. Moreover, filtering that data-set would require to sort the
strv by path and then do prefix-filtering. This is O(n log n), which
would be fine, but still better to avoid.

sd-bus: derive uid from cgroup if possible

Whenever we run in a user context, sd_bus_{default_user,open_user}() and
friends should always connect to the user-bus of the current context,
instead of deriving the uid from getuid(). This allows us running
programs via sudo/su, without the nasty side-effect of accidentally
connecting to the root user-bus.

This patch enforces the idea of making su/sudo *not* opening sessions by
default. That is, all they do is raising privileges, but keeping
everything set as before. You can still use su/sudo to open real sessions
by requesting a login-session (or loading pam_elogind otherwise).
However, in this case XDG_RUNTIME_DIR= will not be set (as usual in these
cases), hence, you will not be able to connect to *any* user-bus.

Long story short: With this patch applied, both:
        - ./busctl --user
        - sudo ./busctl --user
..will successfully connect to the user-bus of the local user.
