    Fail if required extensions are missing

    If the required extensions are missing, we currently log an error
    that is going to be practically ignored. That said, the unfulfilled
    requirement will most definitely going to lead to other failures,
    so we might as well fail fast.

    This patch also cleans up some <barf>dns-integration nonsense</barf>
    within the ML2 framework: the extension must not be declared statically
    as it's being loaded by the extension manager, and this fixes the lousy
    unit tests we have to live with. As for the db base plugin, some cleanup
    is still overdue, but it will have to be taken care of in a follow-up
    patch.
