Using the flag without param would result in using uninitialized

The daemons are wired up to shutdown in responsible to UNIX process
signals, as well as in response to login1 dbus signals, or loss of
desktop session. The latter two options can optionally preserve state
(ie running VMs).
In non-systemd environments, as well as for testing, it would be useful
to have a way to trigger shutdown with state preservation more directly.
Thus a new admin protocol API is introduced
virAdmConnectDaemonShutdown
which will trigger a daemon shutdown, and preserve running VMs if the
VIR_DAEMON_SHUTDOWN_PRESERVE flag is set.
It has a corresponding 'virt-admin daemon-shutdown [--preserve]' command
binding.

When a domain is marked for autostart, it will be started on every
subsequent host OS boot. There may be times when it is desirable to
mark a domain to be autostarted, on the next boot only.
Thus we add virDomainSetAutostartOnce / virDomainGetAutostartOnce.
An alternative would have been to overload the existing
virDomainSetAutostart method, to accept values '1' or '2' for
the autostart flag. This was not done because it is expected
that language bindings will have mapped the current autostart
flag to a boolean, and thus turning it into an enum would create
a compatibility problem.
A further alternative would have been to create a new method
virDomainSetAutostartFlags, with a VIR_DOMAIN_AUTOSTART_ONCE
flag defined. This was not done because it is felt desirable
to clearly separate the two flags. Setting the "once" flag
should not interfere with existing autostart setting, whether
it is enabled or disabled currently.
The 'virsh autostart' command, however, is still overloaded
by just adding a --once flag, while current state is added
to 'virsh dominfo'.
No ability to filter by 'autostart once' status is added to
the domain list APIs. The most common use of autostart once
will be to automatically set it on host shutdown, and it be
cleared on host startup. Thus there would rarely be scenarios
in which a running app will need to filter on this new flag.

Without this change, one can't do something like the following easily:
`virsh pool-list --all --name | xargs -I {} virsh pool-start \"{}\"`
as no pool `"foo "` (with all the spaces) actually exist.
Although the removed comment states that the additional spaces were kept
to maintain backwards compatibility, the commit [0] and the old behavior
are from 2010 when libvirt was at version 0.8.1. For the sake of sanity,
the behavior should be aligned with other parts of the CLI.

When starting a migration with --timeout, we create a thread to call the
migration API and in parallel setup a timer for the timeout. The
description of --timeout says: "run action specified by --timeout-*
option (suspend by default) if live migration exceeds timeout", which is
not really the way this feature was implemented. Before live migration
starts we first need to contact the source to get the domain definition
and send it to the destination where a new QEMU process has to be
started. This can take some (unpredictably long) time while the timeout
timer is already running. If a very short timeout is set (which doesn't
really make sense, but it's allowed), we may even end up taking the
timeout action before the actual migration had a chance to start.
With this patch the timeout is started only after we get non-zero
dataTotal from virDomainGetJobInfo, which means the migration (of either
storage or memory) really started.

It is unclear why clang warns, but gcc does not. Our plugin doesn't
actually use the inline helper in address.h that references g_memdup2,
but we get the warning regardless.
Interestingly removing the 'gmodule.h' include avoids the warning. Since
there is nothing in plugin.c that appears to need gmodule.h, removing it
should be safe & done regardless.
