    SUPPORT.md: clarify support of untrusted driver domains with oxenstored
    
    Add a support statement for the scope of support regarding different
    Xenstore variants. Especially oxenstored does not (yet) have security
    support of untrusted driver domains, as those might drive oxenstored
    out of memory by creating lots of watch events for the guests they are
    servicing.
    
    Add a statement regarding Live Update support of oxenstored.
    
    This is part of XSA-326.
