5e04644e31 fence_virtd: Make the libvirt backend survive libvirtd restarts 
Allow the libvirt backend plugin to survive libvirtd restarts
and crashes. Without this fix, fence_virtd will crash if its
connections to hypervisors fail.

Remove the checkpoint backend plugin, as it used CMAN and openais
checkpoints. Given nobody is using CMAN or openais anymore, the plugin

913e54c544 Current implementation of event listener in virt-serial does not support keepalive, 
it does not generate nor capable to answer to keepalive requests, which
causes libvirt connection to disconnect every 30 seconds (interval*timeout
in libvirtd.conf). Furthermore, it does not clean up filehandlers and leaves
hanging sockets. Also, if other thread opens its own connection to libvirt
(i.e. checkpoint.c), event function in virt-serial.c just updates event listener
file handler with a wrong one, what causes checkpoint.c malfunctions, fence_virtd hangs
and so on. This patch uses default event listener implementation from libvirt and
resolves theese problems.
