* qemud/remote.c, src/remote_internal.c: Fix virDomainGetVcpus
	  in the remote case.
	* src/libvirt.c: Allow virConnectListDomains,
	  virConnectListDefinedDomains, virConnectListNetworks and
	  virConnectListDefinedNetworks to work in the case where
	  they are called with maxids/maxnames == 0.
	* src/remote_internal.c: Fix virDomainGetMaxVcpus in remote
	  case so that it copies sufficient data.
	* src/xen_unified.c: Remove autostart functions.
