[libvirt] [PATCH 12/13] virsh: Introduce connection handler

[Erik Skultety]

Before any virsh command can be executed, client connection to daemon
needs to be checked, i.e. first we try to reconnect if needed and then
check the connection usability which is connection type specific. This
handler is registered as client hook.
