This makes easier to import right objects in submodules (only one object). This also implement lazy connection - at first access, not at module import, which speeds up tools, which doesn't need runtime information (like qvm-prefs or qvm-service). In the future this will ease migration from xenstore to QubesDB. Also implement "offline mode" - operate on qubes.xml without connecting to VMM - raise exception at such try. This is needed to run tools during installation, where only minimal set of services are started, especially no libvirt.
