Add pvsDomainDefineXML functions, it works only for existing domains for the present. It's too hard to convert libvirt's XML domain configuration into PVS's one, so I've decided to compare virDomainDef structures: current domain definition and the one created from XML, given to the function. And change only different parameters. Only description change implemetented, changing other parameters will be implemented later.
