From: pasquale <pasquale@pasquale-VPCEB1A4E>
-Added the following bindings:
--virDomainGetCpuStats
--virNodeGetCpuStats
--virDomainShutdownFlags
--virDomainDestroyFlags
-Added following classes
--org/libvirt/CPUStatistic giving cpu stats in user friendly form
--org/libvirt/jna/VirUnion binding
--org/libvirt/jna/virDomainCPUStats type
--org/libvirt/jna/virNodeCPUStats type
--org/libvirt/jna/virTypedParameter biding
