Wrap the new virConnectDomainQemuMonitorEventRegister function
added in libvirt 1.2.3. This patch copies heavily from
network events (commit 6ea5be0) and from event loop callbacks
in libvirt-override.c, since in the libvirt_qemu module, we
must expose top-level functions rather than class members.
* generator.py (qemu_skip_function): Don't generate event code.
(qemuBuildWrappers): Delay manual portion until after imports.
* libvirt-qemu-override.py (qemuMonitorEventRegister)
(qemuMonitorEventDeregister): New file.
* libvirt-qemu-override.c
