spec: clean up libvirtd and virtlockd service mgmt
- systemctl and the %systemd_* RPM macros can take multiple unit names in the one invocation. Make use of this to avoid repeated systemd daemon reloads. - virtlockd was only properly enabled and disabled when using systemd, but when systemd RPM macros were not available (e.g. on Fedora < 18). Make sure it's enabled when systemd RPM macros are present, or when using initscripts. - Always use "reload" on virtlockd, not "condrestart". This allows it to cleanly re-execute itself without losing running state. Ignore any error should the reload fail. - Move the reloading of virtlockd and libvirtd via their initscripts into the daemon package's %postun scriptlet. These services must be restarted after all of the libvirt-daemon-driver-* packages have been upgraded during the same RPM transaction. - Add a %triggerpostun executed only when upgrading an older libvirt-daemon. As an older package would only reload libvirtd during %post, and the newer package would only reload libvirtd during %postun, such an upgrade would not reload libvirtd at all without the trigger.

LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed. Daniel Veillard <veillard@redhat.com>
Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
