    xen-xm: Generate UUID if not specified
    
    Parsing xen-xm format configuration will fail if UUID is not
    specified, e.g.
    
    virsh domxml-from-native xen-xm some-config-without-uuid
    error: internal error parsing xm config failed
    
    Initially I thought to skip parsing the UUID in xenParseXM() when
    not present in the configuration, but this results in a UUID of
    all zeros since it is never set
    
    virsh domxml-from-native xen-xm /tmp/jim/bug-773621_pierre-test
    <domain type='xen'>
      <name>test</name>
      <uuid>00000000-0000-0000-0000-000000000000</uuid>
      ...
    
    which certainly can't be correct since this is the UUID the xen
    tools use for dom0.
    
    This patch takes the approach of generating a UUID when it is not
    specified in the configuration.
