[libvirt] [PATCH] [4/6] Add the script hook support to the libvirt daemon



Add the script hook support to the libvirt daemon

It supports 3 kind of probing times, at daemon startup, when the
daemon reloads its drivers on SIGHUP and when the daemon exits

* daemon/libvirtd.c: daemon hooks for startup, reload and exit
