[libvirt] [PATCH v3 09/16] util: Introduce virObjectLoookupHashGet{UUID|Name}



Add a pair of accessor API's for the object elements which will return
the requested key value from the object to the caller.

It is up to the caller to check the returned key value and error if the
return value is NULL.
