    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.
