[libvirt] [PATCH 24/41] nodedev: introduce virtnodedevd daemon

The virtnodedevd daemon will be responsible for providing the nodedev API driver functionality. The nodedev driver is still loaded by the main libvirtd daemon at this stage, so virtnodedevd must not be running at the same time. Signed-off-by: Daniel P.
