If a user hot-attaches the guest agent channel libvirt would ignore it until the restart of libvirtd or shutdown/destroy and start of the VM itself. This patch adds code that opens or closes the guest agent connection according to the state of the guest agent channel according to connect/disconnect events. To allow opening the channel from the event handler qemuConnectAgent needed to be exported.
