    libxl: Add debug statements

    Over several years of debugging reports related to VM shutdown, destruction,

    and cleanup, I've found that logging of all events received from libxl and

    logging the entry of libxlDomainCleanup has proven useful. Add the these

    debug messages upstream to aid in future debugging.
