    tools/xenstored: Use priv_domid for manual nodes and permission
    
    Usually, priv_domid == dom0_domid == 0, and that is what is expected.
    If we rename s/dom0_domid/store_domid/, it seems more likely we want to
    actually have the priv_domid as the owner.
    
    That leads to follow on changes to ensure that the priv_domid is created
    first.
