[PATCH 08/26] remote: always invoke virStateStop for all daemons
Currently the virStateStop method is only wired up to run save for
the unprivileged daemons, so there is no functional change.
IOW, session exit, or host OS shutdown will trigger VM managed saved
for QEMU session daemon, but not the system daemon.
This changes the daemon code to always run virStateStop for all
daemons. Instead the QEMU driver is responsible for skipping its
own logic when running privileged...for now.
This means that virStateStop will now be triggered by logind's
PrepareForShutdown signal.
