libxl: Add debug statements

Browse Source 
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.
