[libvirt] [PATCH v3 04/16] util: Introduce virObjectLookupKeysGet{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.
