This patch adds libvirt_domain_send_key_api which calls to
virDomainSendKey libvirt API function to send key press events to a
domain. The PHP bindings already have libvirt_domain_send_keys function
which uses VNC to provide similar functionality but that has limited
use cases and depends on a command line VNC client as well as VNC
server being present which is not always the case.
