this patch fix the wrong sequence for fd and timeout register. the sequence was right in dfa1e1dd for fd register, but it changed in e0622ca2. in this patch, set priv, xl_priv in info and increase info->priv ref count before virEventAddHandle. if do this after virEventAddHandle, the fd callback or fd deregister maybe got the empty priv, xl_priv or wrong ref count. after apply this patch, test more than 100 rounds passed compare to fail within 3 rounds without this patch. each round includes define -> start -> destroy -> create -> suspend -> resume -> reboot -> shutdown -> save -> resotre -> dump -> destroy -> create -> setmem -> setvcpus -> destroy.

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.
