selinux: fix SEGV during switch-root if SELinux policy loaded

If you've got SELinux policy loaded, label_hnd is your labeling handle.
When systemd is shutting down, we free that handle via mac_selinux_finish().

But: switch_root() calls mkdir_p_label(), which tries to look up a label
using that freed handle, and so we get a bunch of garbage and eventually
SEGV in libselinux.

(This doesn't happen in the switch-root from initramfs to real root because
there's no SELinux policy loaded in initramfs, so label_hnd is NULL and we
never attempt any lookups.)

So: make sure that mac_selinux_finish() actually sets label_hnd to NULL, so
nobody tries to use it after it becomes invalid.

It was possible for useful data to be left in the buffer after some entries were

Fix this by enabling a handler wherever we process input data and do not exhaust data
from the input buffer (i.e. when EAGAIN was not encountered). The handler runs until
we encounter EAGAIN.

Looping over the input data is done in this roundabout way to allow the event loop

bus-proxy: complain only once about queue overflows

If the local peer does not dispatch its incoming queue, the bus-proxy will
slowly fill its outgoing queue. Once its full, it will continously
complain that it cannot forward its messages.

As it turns out, pulseaudio does have an idle background dbus connection
that is not integrated into any mainloop (and given that gdbus and
libdbus1 both support background shared connections, PA is probably not
the only example), therefore, the bus-proxy will loudly complain if it
cannot forward NameOwnerChanged events once the queue is full.

This commit makes the proxy track queue-state and complain only once the
queue runs full, not if it is already full.

A PA bug-report (and patch) has been filed, and other applications should
be fixed similarly. Hence, lets keep the error message, instead of
dropping it. It's unused resources we really want to get rid of, so

The SETTLE event is sent after systemd-logind and udev enumerations are
